应用程序启动时如何加载文件的内容 [英] How Do I Load Contents Of A File When The Application Start

问题描述

我希望应用程序从应用程序启动时加载文件内容。您将不得不假设要加载设置的文件名为Settings.ini;并且与应用程序的exe文件位于同一目录中。使用Assembly.GetExecutingAssembly（）获取exe文件的位置。当用户单击确定按钮时，它还必须保存到exe文件位置中的settings.ini文件。



[OP代码]

I want an application to load the file contents from when the application starts. you will have to assume that the file to load the settings from is named Settings.ini; and is located in the same directory as the application's exe file. using Assembly.GetExecutingAssembly() to get the location of the exe file. When the user clicks the Ok button, it must also save to the settings.ini file in the exe files location.
