C# - Generic Action? -

I am using .NET Framework 4.0. Looking for the document for action, they compare this example to the representative of the action:

  representative of zero performance messages (string message); Public Category TestCustomDelegate {Public Fixed Zero Main () {DisplayMessage messageTarget; ...}}   
 and:  
  public class test action 1 {public static zero main () {action & lt; String & gt; MessageTarget; ...}}   
 But how do I create it by using an action instead of a representative?  
  Zero display message message & lt; T & gt; (T message); Public Category TestCustomDelegate {Public Fixed Zero Main () {DisplayMessage & lt; String & gt; MessageTarget; ...}}   
 Edit: I forgot the definition of my message, the goal declaration was added to it now.   
 
 
 Your representative will be absolutely  action & lt; T & gt; , but with a different name  
 You can use it in the same way.
