Strange behavior when setting the icon of a window.

[hansolox1]

The following program simply sets the icon of a form called form1. When I
get the name of the embedded icon using GetManifestReso urceNames(), I store
the name in a string variable called s. The value of s is "test2.icon1.ic o".
This program will compile and run just fine from visual studio .net 2003
using .net 1.1 and also will compile and run just fine using csc form1.cs
/resource:icon1. ico.

Now, I created a new string called s2 and just simply stored the value
"test2.icon1.ic o" in it. When I use s2 instead of s as a parameter to
GetManifestReso urceSteam, the program will compile and run just fine in
Visual Studio 2003 but when compiled from the command line using cs form1.cs
/resource:icon1. ico, the GetManifestReso urceString() method does not return a
valid string. This is really strange because the s and s2 strings are
identical.

Is this a bug or am I missing something?

Here is the code:
using System;
using System.Drawing;
using System.Collecti ons;
using System.Componen tModel;
using System.Windows. Forms;
using System.Data;
using System.Reflecti on;
using System.IO;
using System.Diagnost ics;

namespace test2
{
public class Form1 : System.Windows. Forms.Form
{
private System.Componen tModel.Containe r components = null;

public Form1()
{
InitializeCompo nent();
}

protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Disp ose();
}
}
base.Dispose( disposing );
}

private void InitializeCompo nent()
{
this.Load += new System.EventHan dler(this.Form1 _Load);
}

static void Main()
{
Application.Run (new Form1());
}

private void Form1_Load(obje ct sender, System.EventArg s e)
{
Stream imgStream = null;
Assembly a = Assembly.GetExe cutingAssembly( );
string [] resNames = a.GetManifestRe sourceNames();
foreach(string s in resNames)
{
if(s.EndsWith(" .ico"))
{
string s2 = "test2.icon1.ic o";
imgStream = a.GetManifestRe sourceStream(s2 );

if( !(null==imgStre am) )
{
System.Drawing. Icon ico = new Icon(imgStream) ;
this.Icon = ico ;
}
}
}
}
}
}

This code is stored in Form1.cs and added to a project called test2. It
also needs an embedded icon file called icon1.ico.

If this program is executed with:

imgStream = a.GetManifestRe sourceStream(s2 );

The program will work from Visual Studio 2003 but not at a command line
using csc to compile.

If this program is executed with:

imgStream = a.GetManifestRe sourceStream(s) ;

The program will execute properly from Visual Studio 2003 and at a command
line using csc.

Thanks for the help.

If anyone is interested, the behavior noted is because the
/resource:icon1. ico command line parameter to csc embeds the icon in the
executable program as icon1.ico but Visual Studio embeds the icon as
test2.icon1.ico . This is why the EndsWith() worked for csc and Visual Studio
but the use of test2.icon1.ico failed when compile by csc.
