这个是源码：是在一个窗体中拖入一个exe文件可以获取，你可以修改一下
[DllImport("Shell32.dll")]//引入"Shell32.dll"

}
答案补充
public static void GetIcon(string path)
{
SHFILEINFO info = new SHFILEINFO(true);
int cbFileInfo = Marshal.SizeOf(info);
SHGFI flags;
flags = SHGFI.Icon | SHGFI.SmallIcon | SHGFI.UseFileAttributes;
SHGetFileInfo(path, 256, out info, (uint)cbFileInfo,flags);
答案补充
MessageBox.Show(info.attributes.ToString());
MessageBox.Show(info.hIcon.T oString());
MessageBox.Show(info.iIcon.ToString());
MessageBox.Show(info.szDisplayName);
MessageBox.Show(info.szTypeName);
}

icon图标库}
答案补充
void Form1_DragDrop(object sender, System.Windows.Forms.DragEventArgs e) {
string path = ((System.Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString();
this.pictureBox1.Image = GetIcon(path, false).ToBitmap();
}
终于Over了，受不了问问了
