Can you define and call a method inside another method?

Question

And if you can define and call a method inside another method, then can you still call that method outside that method?
E.g
static void
Main (strings[] args)
{
int Inside_Method()
{
//Some code;
}
}
Inside_Method() ;

Answer 1

You can create local functions since C# 7.

You can also use lambdas as inner functions. C# even supports closures with the use of local functions or lambdas.

Here's a simple example of an inner / local function:
