Simple(?) Generics question [modified]
-
Any ideas what I'm really meant to be doing in the lines marked as "won't compile" below?
using System; namespace Test { public class MyClass : GenericsTest<> { public void DoSomething() { base.DoSomething(); } } public class GenericsTest<> where T : class { SomeHelperClass<> helper; public GenericsTest() { helper = new SomeHelperClass<>(); } public void DoSomething() { helper.DoSomething(T); // won't compile helper.DoSomething(this); // won't compile } } public class SomeHelperClass<> where T : class { public void DoSomething(T target) { } } }TIA! -- modified at 21:11 Thursday 3rd August, 2006 Bah, the lt's and gt's get nuked when posting - just imagine the double lt's and gt's are actually single.. -- modified at 21:12 Thursday 3rd August, 2006 -

Or you could check the 'Ignore HTML tags in this message (good for code snippets)' box.

T is a type. You want to pass in an instance of T. By the way, posting error messages is far more helpful that 'it won't compile'

That should compile.

That shouldn't compile. You are clearly passing the wrong type.
