我如何从app.config文件中读取

问题描述

我有一个app.config文件，我有一个网址，其列为

I have a app.config file that I have a url in and its listed as

<appSettings>
     <add key="web" value="http://URL HERE"/>
  </appSettings>

然后在我有的文件中



ChatMessengerService.Messenger messenger = new ChatMessengerService.Messenger（）;





messenger.Url = System.Configuration.ConfigurationManager.AppSettings [web];

bool loginSucces = messenger.Login（用户名，sha1HashStr）;





然而它不读，但如果我硬编码它会工作得很好



任何帮助都会很好。

then in a file I have

ChatMessengerService.Messenger messenger = new ChatMessengerService.Messenger();


messenger.Url = System.Configuration.ConfigurationManager.AppSettings["web"];
bool loginSucces = messenger.Login(username, sha1HashStr);


however its not reading but if I hardcoded the url it will work just fine

Any help would be nice.

推荐答案

<configuration>
  <appSettings>
    <add key="web" value="http://URL HERE" />
  </appSettings>
</configuration>

然后使用System.Configuration添加以下引用

;

最后在你的代码中你必须这样写，

messenger.Url = ConfigurationManager.AppSettings [web];

Then add the following reference
using System.Configuration;
And finally in your code section you have to write like this,
messenger.Url = ConfigurationManager.AppSettings["web"];
