What is Method Overriding? How to override a function in C#?

Use the override modifier to modify a method, a property, an indexer, or an event. An override method provides a new implementation of a member inherited from a base class. The method overridden by an override declaration is known as the overridden base method. The overridden base method must have the same signature as the override method.
You cannot override a non-virtual or static method. The overridden base method must be virtual, abstract, or override. (More...)

Can we call a base class method without creating instance?

Its possible by inheriting from that class also.

Its possible from derived classes using base keyword. (More...)

Difference between type constructor and instance constructor? What is static constructor, when it will be fired? And what is its use?

(Class constructor method is also known as type constructor or type initializer)
Instance constructor is executed when a new instance of type is created and the class constructor is executed after the type is loaded and before any one of the type members is accessed. (It will get executed only 1st time, when we call any static methods/fields in the same class.) Class constructors are used for static field initialization. Only one class constructor per type is permitted, and it cannot use the vararg (variable argument) calling convention. (More...)

What method removes the value from the top of a stack?

The pop() member method removes the value from the top of a stack, which is then returned by the pop() member method to the statement that calls the pop() member method. (More...)

How can you reference current thread of the method ?

"Thread.CurrentThread" refers to the current thread running in the method."CurrentThread" is a public static property. (More...)

How do I call a member method and pass a primitive type (Value Type) by reference?

Use the ref keyword when declaring the parameter of the method, for example:

public bool GetValue( ref int returnValue );

This will pass the numeric by reference.You can modify the value of returnValue within the body of GetValue and it will persist when the method call returns. (More...)
