C# inheritance generic classes with constraints

Question

So, I have a interface:

interface A<SomeType>
{
    SomeType Abc(SomeType);
    .....
}

and I have an class:

class B<ShouldBeClassA<AnyType>> 
     where ShouldBeClassA<AnyType> : A<AnyType>
{ ShouldBeClassA<AnyType> someVariable; .....}

But this is causes syntax error's, what i want, is to force someVariable to be derivative of

A<AnyType>

so i can do that:

class B......
{
    ....
    void Method()
    {
        someVariable.Abc(anyTypeVariable);
    }
 ......}

Can u pls tell me, how to fix that?

Here is the actual code:

public interface IGenericTeacher<Genome<GenomeType>>
    where Genome<GenomeType> : IGenome<GenomeType>
{

    /// <summary>
    /// Pass the tests and save the results.
    /// </summary>
    void PassTests();

    /// <summary>
    /// Passing generation, according to the results.
    /// </summary>
    void PassGeneration();

}


public interface IGenome<GenomeType>
{
   .......

where ShouldBeClassA<AnyType>> : A<AnyType> has an extra >, that's your syntax error. — Sergey Kalinichenko

C# does not have templates. It has Generics. The generic type argument can be constrained, which is what where is. Ive suggested an edit to the title and tags to reflect this. — pinkfloydx33

Your interface should be:

public interface IGenericTeacher<T> where T : IGenome<T>
{
    //...
}
