OpenFileDialog中的异常

问题描述

你好会员，
我在使用OpenFileDialog时遇到异常，以下是代码

hello members,
i m getting an exception while working with OpenFileDialog,following is the code

private void btnBrowse_Click(object sender, EventArgs e)
       {
           OpenFileDialog f = new OpenFileDialog();
           if(f.ShowDialog()==DialogResult.OK)
           {
               txtDoc.Text = f.FileName;
           }
       }

异常消息是:

必须先将当前线程设置为单线程单元(STA)模式，然后才能进行OLE调用.确保您的Main函数上已标记STAThreadAttribute.仅当将调试器附加到进程时，才会引发此异常.


请帮助我...为什么我要得到这个消息...我已经包含了所有必需的名称空间...

and the exception message is:

Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process.


plz help me...why m i getting this msg...i have included all the necessary namespaces...
