I am trying to come up with the best way to get only certain properties from a type using reflection. How can I differentiate the properties from each other?
I understand that I can use binding flags or name. But say I want only a certain four properties. Would the best way be to create a custom attribute for the ones I want then loop through all of the properties to see if they have that attribute?
I have a very simple setup, single mycontrol.ascx with assoicated mycontrol.ascx.designer.vb and mycontrol.ascx.vb file. mycontrol.ascx embeds a single reference to a custom control: "MyMenu":
<mM:myMenu id="myMenu1" runat="server" />
This has created a protected reference in the mycontrol.ascx.designer.vb file:Protected WithEvents myMenu1 As Global.CustomControls.MyMenuNow, when I breakpoint the Page_Load() event of mycontrol.ascx, and inspect the members returned from the type via:
Me.GetType().GetMembers()
I cannot any reference to myMenu1. If I look at the control with intellisence, the property is accessible: Me.myMenu1 Can anyone explain exactly what I'm missing and what I need to do to access designer created properties at runtime through reflection?
I am trying to create instance of class by using reflection in ASP.net web site. Class ClassName is defined and located in App_code folder. Following line returns null, what could be wrong.
Type type = Type.GetType("NameSpace.ClassName", false, true);
I want to retrieve private (implementation and other) methods of a class which implements an interface and also is derived from (inherits) a base class.
How can I achieve this using reflection? Is there anyother way to achieve this?
This is wat m tryin to do. I need to view these private methods and their contents, I don't want to invoke them.
Dim assembly As System.Reflection.Assembly Dim assemblyName As String assemblyName = System.IO.Path.GetFullPath("xyz.dll") assembly = System.Reflection.Assembly.LoadFile(assemblyName) assembly.GetType("myClass").Getmethods(Bindings.NonPublic) assembly.GetType("myClass").GetMethods(BindingFlags.NonPublic) isn't working
I am facing challenge of changing action attribute of html form tag. As my application is on shared hosting (medium trust) environment of godaddy server, I cannot use reflection to get control adapter of html tag page. So, I cannot use the following code in my Url Rewriting module.
[Code]....
Is there any otherway to implement the same functionality without reflection?
Using the following Webservice definition using aClientArgs as a complex type:
[System.Web.Script.Services.ScriptService] public class Controller : System.Web.Services.WebService { [WebMethod] public void save_client(aClientArgs client) { // Save client data } } Then defining aClientArgs as a sub-class: public class aArgs { public string id = null; public string name = null; } public class aClientArgs : aArgs { public string address = null; public string website = null; } Returns the following WSDL fragment for the save_client args: <save_client xmlns="http://tempuri.org/"> <client> <address>string</address> <website>string</website> </client> </save_client> When I'm expecting the following: <save_client xmlns="http://tempuri.org/"> <client> <id>string</id> <name>string</name> <address>string</address> <website>string</website> </client> </save_client>
So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?
I'm reading a bit of Pro ASP.NET MVC Framework and following a few tutorials written in the book. In the very first tutorial, creating a MVC site for dinner (PartyInvites), I encoutered this problem. While I try to reference some properties from Model class, the compilation error occured. Eg. the following code failed.
[Code]....
and the error message
Compiler Error Message: CS1061: 'object' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) I imported the Model folder into the controller too. I dunno what I'm missing here. Sorry, if it sounds a bit umm hard to understand cuz I just started picking up MVC this morning. Looking for any input.
There is a SearchPage which has a properties ErrorMessage, SuccessMessage etc. This is basically a MVP pattern so for each page(view) there is IView that contains definitions for all the properties
I am using decoratoe pattern to set these peoperties dependingon the message type. There is another Interface IBaseMessage which has a method DisplayMessage() and a class BaseMessage which implements the interface. This class has a definition of the view
I have added a static string variable inside a web page with it's class named VersionBase. The class is public, the variable is public, why can't I simply do VersionBase.MyString from anywhere inside the project like I can do with any other class?
I am interested to know what happens with unused properties of a class when an object is instantiated?
Are there performance hits for having additional unused properties? What about complex properties that are accessing the database, but I'm not using them, are they still being loaded?
I am successfully injecting base class properties with spring.net with just a class that inherits from a base abstract class. Lets say Class MyClass : MyBase, and I am successfully setting a property like this:
Where MyBaseClassProperty is a property on the base class. Now I have another abstract class between the old base class and the instantiable class and I am trying to set properties on both the abstract classes. So MyClass : MyNewBaseClass and MyNewBaseClass : MyBaseClass. I have an additional property on the new base class (MyNewBaseClassProperty) and I am trying to inject it like this:
The property on the old base class is being injected but the one on the new one is not - and I am not getting an error or anything (so I am pretty sure my config is good), that property is just null! I am on asp.net (not MVC) and the class MyClass is a user control (ascx).
In my controller have a FormViewModel which inherits from a domain class declared in dbml. In the constructor of the FormViewModel I want to do a shorthand assignment to the inherited class properties with the passed in object (ie thisPerson) without iterating through each property of the inherited class and assigning its value with corresponding property in the passing in object. Should I use super, base, this, or something else?
I am using a custom membership provider. I want to expose additional properties under User class.
So in my custom membership provider class I added few Properties (FirstName, LastName, Address, etc) and set their value in ValidateUser(). However back in aspx.cs if I type User. I do not see FirstName, LastName and Address in intellisense.
Is what I'm attempting to do even possible? Or do I need to resort to using my own custom user class? In which case I wouldn't need to use custom membership provider because I can program my custom user class to do everything that custom membership provider can do. Only thing is I would need to pass this user object in session object.
Currently I have a class that represents a document. This document needs to be displayed as HTML. I would like to have a method to call such as GetHTML() that would then call GetHTML() on any properties/sections of the document that needed to be rendered. I was initially thinking about using linq and XElement but am wondering if that may cause issues with certain tags in HTML. Would I better off using an HtmlTextWriter?
I have a vb.net class with properties defined as follows:
Private m_Property1 As String Public Property Property1() As String Get Return m_Property1 End Get Set(ByVal value As String) If IsNothing(value) Then m_Property1 = String.Empty Else m_Property1 = value End If End Set End Property
I can then set the values as follows:
classname.Property1 = "myvalue"
How do I set the value of a property that is defined dynmically eg
1) What Is The Meaning of dr.GetOrdianal In ASP.NET Class File? What Is The Purpose Of The Same? Is It Compulsory To Write dr.GetOrdinal While Fetching Any Value From Database?
And
2) What Is The Purpose of Properties (Get & Set ) In Class File? Will It Saves Our Time Of Compilation?
public class Foo { public String A {get;set;} public DateTime B {get;set;} // .. and other properties like public String Intern {get;set;} }
I'm binding that Item to a DetailsView in Editmode. (I bind a List containing a single object of Foo, becuase I do recall that I can only bind IEnumerable<> classes to the DetailView)The binding is done via a ObjectDataSource
