Question

I have my generic class and two methods that accept as argument a delegate (generic or not)

public sealed class MyClass<TResult>
{
   public MyClass ContinueWith(ThreadInfo.Parameterized arg)
   {
   }

   public MyClass<TResult> ContinueWith<TResult>(ThreadInfo<TResult>.Parameterized arg)
   {
   }
}

Where:

public sealed class MyClass
{
}

I have the Compiler Warning (level3) CS0693 but if I remove <TResult> from the second method:

public MyClass<TResult> ContinueWith(ThreadInfo<TResult>.Parameterized arg)

I can’t use this method anymore, if I try I get a compiler error because the compiler thinks I want to use the first method.

How can I solve this problem?

Answer 1

Well it sounds like you really want:

public MyClass<TResult> ContinueWith(ThreadInfo<TResult>.Parameterized arg)

In other words, using the TResult parameter declared at the type level.

If you really want it to be a generic method (i.e. introducing a new type parameter) you have to give it a different name:

public MyClass<T2> ContinueWith<T2>(ThreadInfo<T2>.Parameterized arg)

(It’s possible that you may want to return a MyClass<TResult> here, or something similar – we don’t really know what you’re trying to achieve, which makes it hard to give detailed help.)
