仅传递定义其他泛型的一种泛型类型

Question

I have the following method:

public void SomeMethod<TParser, T1, T2> () where TParser : IParser<T1, T2>, new() 
{
   ...
}

and an IParser<T1, T2> interface and a class which implements it:

public interface IParser<T1, T2>
{
   ...
}

public class Parser : IParser<string, int>
{
   ...
}

Now my questions is would it be possible to only pass TParser to the method, since there is a constraint set which kinda defines T1 and T2 . So would it be possible to do something like the following:

SomeMethod<Parser>();

I would guess it isn't possible, but would there be something similar?

Answer 1

What you can do is to define a non-generic version of your interface. And derive your generic interface from it and use non-generic version as a constraint. And if you have parameters of type T1 and T2 this won't be useful.

internal interface IParser
{
... // if you can define any. or it can be empty also
}

public interface IParser<T1, T2> : IParser
{
   ...
}

And change your method signature to this :

public void SomeMethod<TParser> () where TParser : IParser new() 
{
   ...
}
