比较开放通用参数与开放通用接口类型

Question

Is it possible (in c# ) to compare an open generic parameter eg T in:

public void CompareMethod<T>() { ... }

with the type of an open generic interface (or class)?
Here is an example interface:

public interface IExample<T> { }

And then somehow inside the method compare them like this:

public void CompareMethod<T>()
{
    if (typeof(IExample<>) == typeof(T))
    {
        //execute
    }
}

The if body won't execute when called the method like this:

CompareMethod<IExample<object>>();

It is important that I don't know in advance what closed types will be entered in the open generic parameter of the CompareMethod .

Answer 1

You need to call GetGenericTypeDefinition() on T to be able to compare it with IExample<> :

public void CompareMethod<T>()
{
    if (typeof(T).IsGenericType && 
        typeof(T).GetGenericTypeDefinition() == typeof(IExample<>)) {
    {
        //execute
    }
}
