大家好，

当我按一下按钮以调用打开的对话框时，出现以下错误

有关调用的详细信息，请参见此消息的末尾
即时(JIT)调试，而不是此对话框.

该代码在我的系统中运行正常，可能是JIT问题卸载JIT并尝试相同的代码. 这段代码可以在我的机器上完美运行...
这可能是您电脑中的其他问题....

解决方案

The code is working fine in my system,it might be a problem with JIT.Uninstall JIT and try the same code.

please provide the piece of code, not only the error.

private void button1_Click(object sender, EventArgs e)
{
            OpenFileDialog openfiledialog = new OpenFileDialog();
            openfiledialog.Filter = "xml files|*.xml";
            openfiledialog.Multiselect = false;
            DialogResult dr;
            dr = openfiledialog.ShowDialog();
            if (dr == DialogResult.OK)
            {
                MessageBox.Show("You have clicked ok");
            }
}

This code is perfectly running on my machine...
It may be other problem in your pc....
