.net - Cast generic type parameter to a specific type in C#

Question

If you need to cast a generic type parameter to a specific type, we can cast it to a object and do the casting like below:

void SomeMethod(T t)
{
    SomeClass obj2 = (SomeClass)(object)t;
}

Is there a better way to achieve this, rather than casting it to an object and then to a specific type?

Problem:

I have a generic function which accepts a generic type parameter, inside the function based on a type checking I do some operations like below:

    void SomeMethod(T t)
    {
        if (typeof(T).Equals(typeof(TypeA)))
        {
            TypeA = (TypeA)(object)t;
            //Do some operation
        }
        else if (typeof(T).Equals(typeof(TypeB)))
        {
            TypeB = (TypeB)(object)t;
            //Do some operation
        }
    }

Answer 1

You can use Convert.ChangeType

SomeClass obj2 = (SomeClass)Convert.ChangeType(t, typeof(SomeClass));

Although, keep in mind that this will throw an exception if a cast is invalid.
