在 VS 2010 SP 1 中，我为 .Net Framework 2 创建了 WinForms 应用程序。我尝试从资源中获取图标并将其分配给表单图标：

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

图标资源 icon_gray.ico 从 VS 设计器添加到我的开发人员 PC Windows 7 x86 中的 Resources.resx，带有 .NET Framework 3.5 SP1 和 .NET 4。

但是出现以下错误Windows XP SP 3 with only .NET Framework 2 SP 2

错误：

如何解决这个问题？ 编辑： 用png：

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

一切都很好

对于遇到此问题的人，请确保检查项目属性窗口中的图标以及所有表单中的图标属性。它们都必须是 32x32 才能在 Windows XP 中工作。
