Question

I want to create a function with C# List datatype as a parameter.

public void foo(List<Something> obj)
{
...
}

But I want to pass anykind of List type to the function, I mean, like this

List<Class1> obj1 = new List<Class1>();
foo(obj1);

List<Class2> obj2 = new List<Class2>();
foo(obj2);

Can I do something like this? How to do this? Thanks in advance

Answer 1

use generics.

public void foo<T>(List<T> obj)
{
...
}

call like

 foo<Class1>(new List<Class1>());
 foo<Class2>(new List<Class2>());

The above can be simplified further to by making use of generics type inference

 foo(new List<Class1>());
 foo(new List<Class2>());
