Hi,

I am using an app.config file

XML

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

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

C#

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

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

Can any one guess why it is happening.

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.]
