Checking type parameter of a generic method in C#

Question

Is it possible to do something like this in C#:

public void DoSomething(T t)  
{
    if (T is MyClass)
    {
        MyClass mc = (MyClass)t 
               


        

Answer 1

Starting with C# 7, you can do this in a concise way with the is operator:

public void DoSomething(T value)  
{
    if (value is MyClass mc)
    {
        ...
    }
    else if (value is List lmc)
    {
        ...
    }
}
