Assert.Null

Assert.Null and Assert.IsNull test that the specified object is null. The two forms are provided for compatibility with past versions of NUnit and NUnitLite.

Assert.Null( object anObject );
Assert.Null( object anObject, string message, params object[] parms );

Assert.IsNull( object anObject );
Assert.IsNull( object anObject, string message, params object[] parms );
