在asp.net的一个click事件中,我使用如下代码:
Stream myStream;
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.InitialDirectory = "c:\\";
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
openFileDialog1.FilterIndex = 2;
openFileDialog1.RestoreDirectory = true;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
if ((myStream = openFileDialog1.OpenFile()) != null)
{
// Insert code to read the stream here.
myStream.Close();
}
}
在openFileDialog1.ShowDialog() 这里报错说:
在可以调用 OLE 之前,必须将当前线程设置为单线程单元(STA)模式。请确保您的 Main 函数带有 STAThreadAttribute 标记。 只有将调试器附加到该进程才会引发此异常。
