.NET 2中资源的奇怪问题

Question

In VS 2010 SP 1 I've created WinForms application for .Net Framework 2. And I try to get icon from resources and assign it to form icon:

this.Icon = global::tester.Properties.Resources.icon_gray;

Icon resource icon_gray.ico was added from VS designer to Resources.resx in my developer PC Windows 7 x86 with .NET Framework 3.5 SP1, and .NET 4.

But got the below error in Windows XP SP 3 with only .NET Framework 2 SP 2

Error :

How to fix this? Edit: With png:

pictureBox1.Image = global::tester.Properties.Resources.icon_gray1;

everything is fine

Answer 1

For those who have encountered this problem, make sure you check the icon in the project properties window and also, the icon property in all of you forms. They all have to be 32x32 in order to work in Windows XP.
