我正在开发win应用程序，用于从系统位置检索图像并将其转换为文本文件并保存到系统位置，这是我的工作.我要在安装后接受app.config文件的更改.在此，用户修改app.config文件的参数值(此处是用户选择的驱动器地址)，这意味着在不进行编译的情况下，exe会接受该远程系统中的更改.示例iam在一个系统中创建了一个winapp设置文件和部署对象.
之后，他在那时更改了app.config文件参数(此文件包含系统驱动器位置)，我的应用程序接受该驱动器地址并执行iamge进程.

我对系统中的固定位置有一个想法.但是我想在安装后接受用户的选择.我的代码是(这是从总代码中得到的平安):

I am developing win application for retrive the image from system location and converting into text file and save into system location this is my work. i want to accept the changes of app.config file after instalation.here user modify the app.config file parameter value(here mention the drive address thatis user choice) ,that means with out compilation the exe accept changes in that remote system.for example iam created one winapp setup file and deployee in one system.
aftrer he change the app.config file parameter(this containing system drive location) at that time my application accept that drive address and do iamge process.

I have an idea for fixed location in system. But I want to accept user choice at after instalation. My code is (this is peace of from total code):

    using (stream)
    {
        using (StreamWriter writer = new StreamWriter(stream))
        {
            document.Save(writer);

    }
