Answer 1

你的意思是SaveFileDialog？

从MSDN示例中,稍加修改:

using (SaveFileDialog dialog = new SaveFileDialog())
{
    dialog.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"  ;
    dialog.FilterIndex = 2 ;
    dialog.RestoreDirectory = true ;

    if (dialog.ShowDialog() == DialogResult.OK)
    {
        // Can use dialog.FileName
        using (Stream stream = dialog.OpenFile())
        {
            // Save data
        }
    }
}

Answer 2

Answer 3

我在 C# 中做一个记事本应用程序我遇到了这个场景来保存文件，试试这个。它会完美地工作

 private void saveAsToolStripMenuItem_Click(object sender, EventArgs e)
    {

        SaveFileDialog saveFileDialog1 = new SaveFileDialog();

        saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
        saveFileDialog1.FilterIndex = 2;
        saveFileDialog1.RestoreDirectory = true;

        if (saveFileDialog1.ShowDialog() == DialogResult.OK)
        {


            System.IO.StreamWriter file = new System.IO.StreamWriter(saveFileDialog1.FileName.ToString());
            file.WriteLine(richTextBox1.Text);
            file.Close();
        }



    }
