Is the method Where() using lambda expression returns values immediately.

  
Nope. It is deferred execution. It will return an object which contains the information to execute the query. The actual filtering happens when the enumeration of elements starts.

The enumeration could be started by using a foreach loop. (More...)

What is Lambda Expression?

  
msdn: A Lambda expression is an anonymous function that can contain expressions and statements.

The right side holds the expressions or statements

There are expression lambdas and statement lambdas (More...)

What is a Lambda expression?

  
A Lambda expression is nothing but an Anonymous Function, can contain expressions and statements. Lambda expressions can be used mostly to create delegates or expression tree types. Lambda expression uses lambda operator => and read as 'goes to' operator.

Example: myExp = myExp/10;

The => operator has the same precedence as assignment (=) and is right-associative.

Lambdas are used in method-based LINQ queries as arguments to standard query operator methods such as Where. (More...)

What is Method overloading?

  
Method overloading occurs when a class contains two methods with the same name, but different signatures. (More...)

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 If its a static method.

Its possible by inheriting from that class also.

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