C# - Cannot Implicitly Convert Type System.Collection.Generic.IEnumberable

Mar 8, 2010

I'm receiving this error in my Linq statement ---

Cannot implicitly convert type 'System.Collections.Generic.IEnumerable' to 'hcgames.ObjectClasses.ShoppingCart.ShoppingCartCartAddon'. An explicit conversion exists (are you missing a cast?)

From this query

ShoppingCartItems items = Cart.GetAllItems();
ShoppingCartCartAddons addons = Cart.GetAllAddons();
var stuff = from x in items
select new ShoppingCartItem()
{
ProductID = x.ProductID,
Quantity = x.Quantity,
Name = x.Name,
Price = x.Price,
Weight = x.Weight,
Addons = (from y in addons
where y.ShoppingCartItemID == x.ID
select y)
};

Cannot Implicitly Convert Type 'System.Web.HttpPostedFile' To 'System.Web.HttpPostedFileBase'?

Jun 18, 2010

I have this method which does not build, it errors with the message:

Cannot implicitly convert type 'System.Web.HttpPostedFile' to 'System.Web.HttpPostedFileBase'
I really need this to be of type HttpPostedFileBase instead of HttpPostedFile, I have tried boxing and it does not work:
foreach (string inputTagName in HttpContext.Current.Request.Files)
{
HttpPostedFileBase filebase =HttpContext.Current.Request.Files[inputTagName];
if (filebase.ContentLength > 0)
{
if (filebase.ContentType.Contains("image/"))
{
SaveNonAutoExtractedThumbnails(doc, filebase);
}
}

Cannot Implicitly Convert Type 'System.Exception' To 'string'

Aug 11, 2010

I want to log all errors happened in my App to sql db. I'm passing all exception properties like (ex.Message, ex.Source, ex.StackTrace, ex.TargetSite and ex.InnerException) to stored procedure.

The problem is that when I try to pass the ex.InnerException as string to stored procedure I got this error:

Cannot implicitly convert type 'System.Exception' to 'string'

I tried ex.InnerException.ToString() and Convert.ToString (ex.InnerException) but no success.

Custom Server Controls :: Using The Generic Type 'System.Collections.Generic.IEnumerable' Requires '1' Type Arguments

I'm trying to create a control out of a class I found, and one of the overridden functions is the following:

protected override void PerformDataBinding(IEnumerable data)

However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.

Iterating System.Collection.Generic.List.Add Does Not Work As Expected?

Mar 7, 2010

I was building an application for a project with .NET 3.5 and I noticed a weird behaviour of the List.Add method:

I have built my own class to organize data pulled from a database, and I use a while cycle to iterate through it.

However, when I List.Add(item), the whole content of the list is substituted with the last content pulled.

An example:

Suppose you have 3 users in a DB, each one identified with an ID and a username:

| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |

and you have a "Users" class defined as

public class Users
{
private Int32 iD;
private String username;
public Int32 ID
{
get { return iD; }
set { iD = value; }
}
public String Username
{
get { return username; }
set { username = value; }
}
}

So you write this function:

[... SQL definitions - sdr is a SqlDataReader ...]
List<Users> userlist = new List<Users>();
if (sdr.HasRows) //There are users
{
Users user = new Users();
while (sdr.Read())
{
user.ID = sdr.GetInt32(0);
user.username = sdr.GetString(1);
userlist.Add(user);
}
}

What you expect (I expect) is userlist containing:

| ID | username |
| 1 | John |
| 2 | Fred |
| 3 | Paul |

What I actually get is, instead

| ID | username |
| 3 | Paul |
| 3 | Paul |
| 3 | Paul |

C# - Converting An IEnumberable<string> To IEnumberable<ListItem>

Jan 19, 2011

I'm getting this error which while trying to use the yield return feature in C#. The error appears on the select inside visual studio and I don't really understand it. In my mind I'm converting a string to a ListItem and then returning the lot as an IEnumerable. My understanding of yield return and IEnumerable might very well be off the mark. The commented code is the old school way of doing it which does work properly.

MVC Generic Base View Class / Error Parsing Attribute 'something': Type 'System.Web.Mvc.ViewPage'

Feb 5, 2010

I can have a base class for views in an MVC project like this:

public class BaseViewPage : System.Web.Mvc.ViewPage
{
public string Something { get; set; }
}

And then in the ASPX I can do this:

<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage" %>

This works fine; the problem is when I try to do the same with the generic version:

public class BaseViewPage<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class
{
public string Something { get; set; }
}

When I try to use this from the ASPX, like this:

<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage<SomeClass>" %>

I get the error message:

Error parsing attribute 'something': Type 'System.Web.Mvc.ViewPage' does not have a public property named 'something'.

Notice how it tries to use System.Web.Mvc.ViewPage rather than my BaseViewPage class. To make it more interesting, if I remove the "Something" attribute from the Page directive and put some code in the generic version of BaseViewPage (OnInit for example) the class is actually called / used / instantiated.

So, am I doing something wrong or is this a limitation.

Can't Convert System / Use Its Own Pre Defined Type?

Jan 14, 2010

So, I've been programming for a number of years. Finding some intricately asinine issues w/ ASP.NET and VB.NET as I learn them. How about this one:

[Code]....

The issue is not Date1
The issue is Date2.

No kidding. I had to String.Format Date1 for some odd reason, even though I'd already validated it. And, yes, I tried to parse and convert Date1 but I kept gettting the typical "Argument 'Date2' cannot be converted to type 'Date'." error. (Did you catch the copy & paste? I didn't edit it from my existing error, but Date2 should be Date1.) Yeah, that's the error I'm getting now with the above ...

"Argument 'Date2' cannot be converted to type 'Date'."

Date2 is a system defined type. Why can't the system convert and/or simply use it's own pre-defined type?
