app.config读取问题 [英] app.config reading problem

问题描述

我正在使用app.config文件

Hi,

I am using an app.config file

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
        <add key="test" value="Hi"/>
  </appSettings>
</configuration>

在一个类库项目中，我想访问它的值.
我正在使用

and in a class library project I want to access the value of it.
I am using

string str = new System.Configuration.AppSettingsReader().GetValue("test", typeof(System.String)).ToString();

但是appsettings部分中没有给出该测试的信息.

任何人都可以猜测为什么会发生这种情况.

But it giving that test is not there in the appsettings section.

Can any one guess why it is happening.

推荐答案

您不能在Class-Library Project中使用App.Config. Class-Library Project可以引用该项目的App.Config/Web.Config文件(Windows/Web等)，并在其中添加作为参考.

您可以将appSettings的key保留在Final/Output(Windows/Web等)项目的App.Config/Web.Config文件中，然后进行访问.

已更新-

下面的链接对此主题进行了讨论，当然，除了引用已引用Class-Library项目的Project的App.Config/Web.config设置外，它当然没有提供任何具体的解决方案.

You cannot use App.Config in Class-Library Project. Class-Library Project can refer to App.Config/Web.Config file of the Project(Windows/Web etc.) in which it is added as a reference.

You may keep that key of appSettings in the App.Config/Web.Config file of your Final/Output(Windows/Web etc.) Project, and then access it.

Updated -

Below link has a discussion on this topic, which certainly does not provide any concrete solution other than referencing App.Config/Web.config settings of the Project in which Class-Library project has been referenced.

Edit - Have a look at one more discussion thread on this topic. [Spelling corrections.]

试试这个

try this

string str = ConfigurationManager.AppSettings["test"].ToString();
