Threading and static methods in C#

Question

Here is a meaningless extension method as an example:

public static class MyExtensions
{
    public static int MyExtensionMethod(this MyType e)
    {
        in         


        

Answer 1

Yes, that's a correct assessment. x is a method-local variable, and won't be shared between invocations of MyExtensionMethod.

Answer 2

Quite simply, yes. A static method only means that the method can be called without an object. The local variables within the method are still local.

Answer 3

Yes, each thread gets its own separate local variable. This function will always return 2 even if called by multiple threads simultaneously.
