Answer 1

SaveFileDialog saveFileDialog = new SaveFileDialog();
if (saveFileDialog.ShowDialog() == DialogResult.OK)

}

我的代码：
if (this.saveFileDialog1.ShowDialog()  == DialogResult.OK )
{ 
             //MessageBox.Show(sFileName);
              //写入文件
                string sFileName;
              FileStream fs;
              StreamWriter sw; 
              sFileName = this.saveFileDialog1.FileName;
              fs = new FileStream(sFileName,FileMode.Create);
              sw = new StreamWriter(fs,System.Text.Encoding.Default); ...
               //写入文件
                sw.WriteLine(dr.GetValue(4).ToString() );        
              sw.Close();
              fs.Close();
}
