I try, when I press save in SaveFileDialog
I do something. I trying fix but always something wrong.
SaveFileDialog dlg2 = new SaveFileDialog();
dlg2.Filter = "xml | *.xml";
dlg2.DefaultExt = "xml";
dlg2.ShowDialog();
if (dlg2.ShowDialog() == DialogResult.OK)
{....}
But I have error on OK - which say:
Error: 'System.Nullable' does not contain a definition for 'OK' and no extension method 'OK' accepting a first argument of type 'System.Nullable' could be found (are you missing a using directive or an assembly reference?)
I try fix with this code:
DialogResult result = dlg2.ShowDialog(); //here is error again
if (result == DialogResult.OK)
{....}
Now error is on DialogResult say: 'System.Windows.Window.DialogResult' is a 'property' but is used like a 'type'
I assume that you are referring to WPF
not Windows Form
Here is example of using SaveFileDialog
//configure save file dialog box
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.FileName = "Document"; //default file name
dlg.DefaultExt = ".xml"; //default file extension
dlg.Filter = "XML documents (.xml)|*.xml"; //filter files by extension
// Show save file dialog box
Nullable<bool> result = dlg.ShowDialog();
// Process save file dialog box results
if (result == true)
{
// Save document
string filename = dlg.FileName;
}
Other Example:
In WPF
you have to handle conflict between DialogResult
Enumeration and Window.DialogResult
Property
Try using fully qualified name to refer the enumeration:
System.Windows.Forms.DialogResult result = dlg2.ShowDialog();
if (result == DialogResult.OK)
{....}
