Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
This class allows you to open and overwrite an existing file or create a new file.
Most of the functionality for this class is found in the FileDialog class.
.NET Compact Framework Platform Note: On the Pocket PC, if you do not specify a file name extension, the control appends the extension of the selected type from the dialog box. On Windows CE .NET, the control does not append an extension.
All platforms support the FilterIndex property which returns the index of the selected extension filter.
Example
[Visual Basic, C#, C++] The following example illustrates creating a SaveFileDialog, setting members, calling the dialog box using the ShowDialog method, and opening the selected file. The example assumes a form with a button placed on it.
[Visual Basic] Protected Sub button1_Click(sender As Object, e As System.EventArgs) Dim myStream As Stream Dim saveFileDialog1 As New SaveFileDialog() saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" saveFileDialog1.FilterIndex = 2 saveFileDialog1.RestoreDirectory = True If saveFileDialog1.ShowDialog() = DialogResult.OK Then myStream = saveFileDialog1.OpenFile() If Not (myStream Is Nothing) Then ' Code to write the stream goes here. myStream.Close() End If End If End Sub [C#] protected void button1_Click(object sender, System.EventArgs e) { Stream myStream ; SaveFileDialog saveFileDialog1 = new SaveFileDialog(); saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ; saveFileDialog1.FilterIndex = 2 ; saveFileDialog1.RestoreDirectory = true ; if(saveFileDialog1.ShowDialog() == DialogResult.OK) { if((myStream = saveFileDialog1.OpenFile()) != null) { // Code to write the stream goes here. myStream.Close(); } } } [C++] protected: void button1_Click(Object* /*sender*/, System::EventArgs* /*e*/) { Stream* myStream ; SaveFileDialog* saveFileDialog1 = new SaveFileDialog(); saveFileDialog1->Filter = S"txt files (*.txt)|*.txt|All files (*.*)|*.*" ; saveFileDialog1->FilterIndex = 2 ; saveFileDialog1->RestoreDirectory = true ; if(saveFileDialog1->ShowDialog() == DialogResult::OK) { if((myStream = saveFileDialog1->OpenFile()) != 0) { // Code to write the stream goes here. myStream->Close(); } } }
