Error while using OpenFileDialog(). <<URGENT>> RRS feed

  • Question

  • Hi,

     

    I am having an aspx page from which, on a button click an open file dialog should open up from which i can select a file.

    i wrote the following code on the button's click event.

    OpenFileDialog _filedialog = new OpenFileDialog();

                _filedialog.InitialDirectory = @"C:\";
                _filedialog.Title = "Add Preview Image";
                _filedialog.Filter = "Image files|*.jpeg;*.jpg;*.bmp;*.png";
                _filedialog.RestoreDirectory = true;
                if (_filedialog.ShowDialog() == DialogResult.OK)
                {
                    txtPromoPreviewImagePath.Text = _filedialog.FileName;
                }

     

    Now, when i run the project and click the button, hoping to see the open dialog file browser window, i see this following error.

    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.

    PLEASE HELP.. !

    Thanks, Manu
