Csharp/C Sharp/GUI Windows Form/SaveFileDialog

Call ShowDialog method to show the dialog

 

using System;
using System.Windows.Forms;
class MainClass {
    static void Main(string[] args) {
        SaveFileDialog dlg = new SaveFileDialog();
        if (dlg.ShowDialog() == DialogResult.OK) {
            Console.WriteLine(dlg.FileName);
        }
    }
}

Set CheckFileExists to true

 
using System;
using System.Windows.Forms;
class MainClass {
    static void Main(string[] args) {
        SaveFileDialog dlg = new SaveFileDialog();
        dlg.CheckFileExists = true;
        if (dlg.ShowDialog() == DialogResult.OK) {
            Console.WriteLine(dlg.FileName);
        }
    }
}

Set InitialDirectory for SaveFileDialog

 

using System;
using System.Windows.Forms;
class MainClass {
    static void Main(string[] args) {
        SaveFileDialog dlg = new SaveFileDialog();
        dlg.InitialDirectory = Application.StartupPath;
        if (dlg.ShowDialog() == DialogResult.OK) {
            Console.WriteLine(dlg.FileName);
        }
    }
}

Use Filter in SaveFileDialog to filter file extension

 
using System;
using System.Windows.Forms;
class MainClass {
    static void Main(string[] args) {
        SaveFileDialog dlg = new SaveFileDialog();
        dlg.Filter = "RichText Files (*.rtf)|*.RTF|Text Files (*.txt)|*.TXT" +
          "|All files (*.*)|*.*";
        if (dlg.ShowDialog() == DialogResult.OK) {
            Console.WriteLine(dlg.FileName);
        }
    }
}
