Question

How can we add list or multiple values for a single key in web.config?

For example: I have key named "xyz" it has a list of values, that is , val1, val2, val3 etc.

And this can be obtained in my code as other keys are accessible.

Answer 1

Add in web config as comma separated valued like

<add key = "xyz" value="val1, val2, val3"/>

access them as

  string[]  xyzValues = System.Configuration.ConfigurationManager.AppSettings["xyz"].Split(",");

Answer 2

You can use the appsettings tag

<appSettings>
  <add key="xyz" value="val1;val2;val3" />
</appSettings>

C# Code

string[] values = ConfigurationManager.AppSettings["xyz"].Split(';');
