Accepted answer
A lambda expression with an expression on the right side of the => operator is called an expression lambda. Expression lambdas are used extensively in the construction of Expresion Trees An expression lambda returns the result of the expression and takes the following basic form:

(input-parameters) => expression

The parentheses are optional only if the lambda has one input parameter; otherwise they are required. Two or more input parameters are separated by commas enclosed in parentheses:

(x, y) => x == y

Expresion Trees

Expression trees represent code in a tree-like data structure, where each node is an expression, for example, a method call or a binary operation such as x < y.

Lambda expressions are how anonymous functions are created.
The left side of the lambda operator specifies the input parameters and the right side holds an expression or a code block that works with the entry parameters. Usually lambda expressions are used as predicates or instead of delegates (a type that references a method).

Expression Lambdas
The lambda operator => divides a lambda expression into two parts. The left side is the input parameter and the right side is the lambda body.
