Question : C# and NUnit Framework

I have the  class below--UserInfo. I can insert the following code into main method:to test my class
however I need to use the NUnit Framework to test it (the web-site www.nunit.org). I have attached the NUnit_UserInfo.txt file - I'm using the NUnit Framework to test. Am I using NUnit Framework correctly?? What would be the best approach?? Thanks

b1 = new UserInfo("Bill Smith", "BSMITH");
b2 = new UserInfo("Bill Smith", "BSMITH");
System.Console.WriteLine( b1.Equals(b1) ); // prints true
System.Console.WriteLine( b1.Equals(b2) ); // prints true
