Reading a key from the Web.Config using Configurat

Question

I am trying to read the keys from the Web.config file in a different layer than the web layer (Same solution)

Here is what I am trying:

string userName = System.Configuration.ConfigurationManager.AppSettings["PFUserName"];
string password = System.Configuration.ConfigurationManager.AppSettings["PFPassWord"];

And here is my appSettings in the Web.config file:

<configuration>
   ....
   <appSettings>
      <add key="PFUserName" value="myusername"/>
      <add key="PFPassWord" value="mypassword"/>
   </appSettings>
   ....
</configuration>

When I debug the code username and password are just null, so it is not getting the value of the keys.

What am I doing wrong to read these values?

Answer 1

Full Path for it is

System.Configuration.ConfigurationManager.AppSettings["KeyName"]

Answer 2

There will be two Web.config files. I think you may have confused with those two files.

Check this image:

In this image you can see two Web.config files. You should add your constants to the one which is in the project folder not in the views folder

Hope this may help you

Answer 3

If the caller is another project, you should write the config in caller project not the called one.

Answer 4

  var url = ConfigurationManager.AppSettings["ServiceProviderUrl"];

Answer 5

Also you can try this line to get string value from app.config file.

var strName= ConfigurationManager.AppSettings["stringName"];

Answer 6

Sorry I've not tested this but I think it's done like this:

var filemap = new System.Configuration.ExeConfigurationFileMap();            
System.Configuration.Configuration config =  System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(filemap, System.Configuration.ConfigurationUserLevel.None);

//usage: config.AppSettings["xxx"]
