C# winform程序用 richtextbox 控件直接保存至txt文本文件

 

System.Windows.Forms.SaveFileDialog objSave = new System.Windows.Forms.SaveFileDialog();
objSave.Filter = "(*.txt)|*.txt|" + "(*.*)|*.*";

 objSave.FileName = "文件名" + DateTime.Now.ToString("yyyyMMddHHmm") + ".txt";

 if (objSave.ShowDialog() == DialogResult.OK)
{
       this.txtDetail.SaveFile(objSave.FileName, RichTextBoxStreamType.PlainText);//重点在此句
 }
