程序无法访问程序文件中的文件

问题描述

在我的程序xPro中，我在使用c:\​​ Program Files(x86)\ xPro的目录中的文件时遇到问题.在一种形式下，它会在关闭时将数据版权授予.txt文件.每次我尝试关闭程序时，都会说拒绝对.txt文件的访问.有帮助吗?

以下是表单关闭的代码:

In my program xPro I am having problems with it using files in it''s directory in c:\Program Files(x86)\xPro. In one form it rights data to a .txt file when it closes. Everytime I try to close the program it says that access to the .txt file is denied. Any help?

Here is the code for Form Closing:

TextBox2.Text = ""
        For Each thing As Object In ListBox1.Items
            TextBox2.AppendText(Trim(thing.ToString & vbNewLine))

        Next

        Dim SR As New StreamWriter(My.Settings.MyDirectory + "\Friends.txt")
        SR.Flush()
        SR.Close()
        Dim SR2 As New StreamWriter(My.Settings.MyDirectory + "\Friends.txt")
        SR2.Write(TextBox2.Text)
        SR2.Close()

我现在确实意识到我应该添加一个Try语句，但是无论如何都不能完全解决问题.

I do now realize that I should add a Try statement but eitherway that doesn''t exactly fix the problem.
