[解决办法]
using System.Runtime.InteropServices;

private void button1_Click(object sender, EventArgs e)
{
pictureBox1.Image = Icon.FromHandle(
ExtractIcon(Handle, @ "c:\temp\temp.exe ", 0)).ToBitmap();
}

用下列方法进行调用:
/// <summary>
/// 取得应用程序的ICON图标
/// </summary>

/// <param name= "path "> 应用程序的路径 </param>
/// <returns> 返回ICON图标 </returns>
public static Icon GetSmallIcon(string path)
{
SYSPul.userFun.FileInfo.FileInfomation _info = new SYSPul.userFun.FileInfo.FileInfomation();
SYSPul.userFun.FileInfo.GetFileInfo(path, 0, ref _info, Marshal.SizeOf(_info), (int)(SYSPul.userFun.FileInfo.GetFileInfoFlags.SHGFI_ICON | SYSPul.userFun.FileInfo.GetFileInfoFlags.SHGFI_SMALLICON));
try
{
return Icon.FromHandle(_info.hIcon);
}
catch
{
return null;
}
}

只需要要调用GetSmallIcon(string path)这个方法,传入一个路径就OK了,比如:DLL文件/EXE文件等,都可能可得到它所用的ICO图标的.
