Graphics.CopyFromScreen 未处理Win32Exception 操作成功完成

Question

程序中只要用到CopyFromScreen就报错
 private void Form1_Paint(object sender, PaintEventArgs e)
        {
            e.Graphics.CopyFromScreen(this.Location,
        new Point(4, 4), new Size(10, 10));
        }详细错误信息：

Answer 1

同样的代码我这里没有错误你把工程rebuild一下，重新试试

Answer 2

 e.Graphics.CopyFromScreen(this.Location,
  new Point(4, 4), new Size(10, 10));是不是位置有点不对啊

Answer 3

以上说的都不行，这程序我换了几台机器测试了下，有的行有的不行，不知道什么原因。 可不可能是.net framework 装的不行?

Answer 4

把.net framework2.0及其相关的东西卸载掉就好了。
注：我电脑上装了所有版本的.net framework 不晓得是不是产生了冲突，猜测！
