无法读取Web.Config中的appSettings值 [英] Can't read appSettings value from Web.Config

问题描述

我在我的web.config以下内容：

I have the following in my web.config:

<configuration>
    <appSettings>
        <add key="PsychMon" value="true"/>
    </appSettings>
 . . .
</configuration>

我在我的代码隐藏下面的代码：

I have the following code in my codebehind:

  System.Configuration.Configuration webConfig = 
System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(null) ; 

然而，当我看着webConfig，webConfig.AppSettings.Settings.Count = 0。

However, when I look at webConfig, webConfig.AppSettings.Settings.Count = 0 .

为什么不读应用程序设置？

Why is it not reading the app setting?

我想要做的是能拿到通过设置：

What I want to do is be able to get the setting by using:

          System.Configuration.KeyValueConfigurationElement psych = 
webConfig.AppSettings.Settings["PsychMon"];

我使用C＃3.5，VS 2008

I am using c# 3.5, vs 2008

推荐答案

你为什么不只是写这个？

Why don't you just write this ?

string value = 
    System.Web.Configuration.WebConfigurationManager.AppSettings["PsychMon"];
