I have no problem getting a custom profile class to work as it should in Asp.Net MVC 2, C# -- as long as I am content that the profile info is serialized as xml.The question is how to get it to serialize as Binary, rather than xml -- Is that possible?in the web.config...
<profile defaultProvider="MIProvider" inherits="Models.MbrProfile" automaticSaveEnabled="false">
<providers>
<clear />

How do I get at the data after doing a .sortable serialize? Here is my code :

I have an ASP.NET 1.1 form gathering data on a public-facing site, within a DMZ. The data is represented by a serializable class. My problem is that I need to serialize, encrypt and transmit the data to a Web Service running on an internal server - the service logic should then decrypt and deserialize the data before writing the XML to a shared folder.
Can someone point me in the right direction? What's the most straightforward way of doing this?

I am facing an critical problem in Enum serialization in WCF. Here is the scenario: I have an enum like this...
[Serializable] [DataContract(Namespace = "http://www.geniusdoc.portal.com/serivces/2011/v1/GdService", Name = "AppointmentMode")] public enum AppointmentMode : int { // 1: Email, 2: Phone [EnumMember(Value = "1")] None = 1, [EnumMember(Value = "2")] Email = 2, [EnumMember(Value = "3")] Phone = 3 }
Here I decorated each enum value with [EnumMember], so that I can use the Enum as Data Contract in WCF.
And, AppointmentMode will be saved as INTEGER in database. So I need to serialize this Enum to its value. So I have specified value to each member like... [EnumMember(Value = "1")]
Problems:
If I use the above code as it is...SvcUtil not considering Enum Text, and generating the Enum in Proxy as below...
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "4.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="AppointmentMode", Namespace="http://www.geniusdoc.portal.com/serivces/2011/v1/GdService")] public enum AppointmentMode: int { [System.Runtime.Serialization.EnumMemberAttribute(Value="1")] _1 = 1, [System.Runtime.Serialization.EnumMemberAttribute(Value="2")] _2 = 2, [System.Runtime.Serialization.EnumMemberAttribute(Value="3")] _3 = 3, }
If I remove the Value from [EnumMember(Value = "1")], while deserialization is considering Enum Text, and giving results as below
<AppointmentMode>None</AppointmentMode>
Expected result:
1. Enum in the Client proxy should be same original Enum.
2. Enum Deserialization should consider EnumValue, such a way that it will return
<AppointmentMode>1</AppointmentMode>
How to get this done?

View 9 Replies I'm learning ASP.NET MVC 2 I want to create a wizard-type application. I was reading you can accomplish this with the help of Html.Serialize method in ASP.NET MVC Futures assembly (To help preserve state as you step through views).
I haven't seen that this is even part of MVC 3.0 as well. how certain this feature will be included for sure in the future? I'm a little wary of relying on it being there.
Using the following code:
Private Sub MakeMeSomeXmlBeforeRyanGetsAngry()
Dim db As New MyDBDataContext
Dim customer = From c In db.Customers Select c
Dim dcs As New DataContractSerializer(GetType(Customer))
Dim sb As StringBuilder = New StringBuilder
Dim writer As XmlWriter = XmlWriter.Create(sb)
dcs.WriteObject(writer, customer)
Dim xml As String = sb.ToString
Response.Write(xml)
End Sub
I am attempting to serialize my linq collection of customers. But it keeps throwing
Type 'System.Data.Linq.DataQuery`1[MyDB.Customer]' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. See the Microsoft .NET Framework documentation for other supported types.
My issue is that I have already marked the dbml Serialization Mode to UniDirectional and when I check the dbml codebehind all of the DataContract()> and DataMember()> elements are there.
I am not sure how to proceed. I have tried adding various dataloadoptions and setting deferredloading to false, but no luck.
I am using Flexigrid in my project to add a button on the grid toolbar I can use code like this:
"buttons":[
{"name":"Modifica","bclass":"edit","onpress":"doCommand"},
{"name":"Elimina","bclass":"delete","onpress":"doCommand"}
],
Anyway the "onpress" attribute shall contain a reference to a js callback and so this field shall not be enclosed within quotation marks.
I am using the class JavaScriptSerializer (in the System.Web.Script.Serialization namespace) to do the serialization.
How I have to declare the variable to make JavaScriptSerializer serialize like this?
"buttons":[
{"name":"Modifica","bclass":"edit","onpress":doCommand},
{"name":"Elimina","bclass":"delete","onpress":doCommand}
],

View 3 RepliesI am trying to serialize an object that has a public member of type ArrayList. If I am reading
this correctly, an ArrayList is a serializeable member. My class looks like this:
[DataContract(Name="Family")]
public class Family
{
private int _FamilyID;
[DataMember]
[Code]....
But then I'm serializing more of the properties than I want. I would be happy to either a) figure out how to get DataContractJsonSerializer to serialize my ArrayList or b) get JavaScriptSerializer to have the effect of honoring a datacontract. I understand that JavaScriptSerializer is depricated so I suppose DataContractJsonSerializer is the way to go if possible.
