可以用SaveFileDialog1对话框加上对文件数据操作的类来实现,,用richtextbox自己的属性方法也能行!我以前做过一个记事本程序就是那样的!

添加一个SaveFileDialog,在保存excle选择时候添加
SaveFileDialog1.show()
用法跟OpenFileDialog相同
保存文件的步骤为:
关闭流,特别是写入流
关闭并保存文件
示例代码如下:
Imports System.Windows.Forms
Imports System.IO
Imports System.Text
Sub SaveFileDemo()
'打开文件。如果文件不存在则创建新的文件
Dim myFile As New IO.FileStream("d:\data.txt", _
FileMode.OpenOrCreate, _
FileAccess.Write)
'在文件末尾添加一行
Dim tw As New StreamWriter(myFile)
myFile.Seek(0, SeekOrigin.End)
tw.WriteLine("白刃格斗英雄连英模部队方队亮相阅兵")
'关闭流
tw.Close()
'关闭文件并保存文件
myFile.Close()
End Sub
