What is C# equivalent of Python's functools.partial?

Question

In python we have a functools.partial mechanism. What would be a valid C# equivalent?

For those unfamiliar with the concept, I am looking for the general case, but it could be anything, even:

def add(a: int, b: int):
    return a + b

add_to_one = partial(add, 1)
add_to_one(2)  # This will return 3
