1、SaveFileDialog

            OpenFileDialog openfile = new OpenFileDialog();
            //初始顯示文件目錄
            //openfile.InitialDirectory = @"";
            openfile.Title = "請選擇要發送的文件";
            //過濾文件類型
            openfile.Filter = "文本文件|*.txt|可執行文件|*.exe|STOCK|STOCK.txt|所有文件類型|*.*";
            if (DialogResult.OK == openfile.ShowDialog())
            {
                //將選擇的文件的全路徑賦值給文本框
                textBox1.Text = openfile.FileName;
            }
      

2、SaveFileDialog

 

 SaveFileDialog savefile = new SaveFileDialog();
            //如果文件名未寫后綴名則自動添加     *.*不會自動添加后綴名
            savefile.AddExtension = true;
            savefile.Filter = "可執行文件|*.exe|文本文件|*.txt|STOCK|STOCK.txt|所有文件|*.*";
            if(DialogResult.OK==savefile.ShowDialog())
            {
