C# Switch Statements

Use the switch statement to select one of many code blocks to be executed.

switch(expression) 
{
 case a:
  // code block
  break;
 case b:
  // code block
  break;
 default:
  // code block
  break;
}

This is how it works:

• The switch expression is evaluated once
• The value of the expression is compared with the values of each case
• If there is a match, the associated block of code is executed
• The break and default keywords will be described later in this chapter

Being a reference to the method, a delegate in C# works like a function pointer in C and C++. As compared to a function pointer, a delegate in C# is objected-oriented, secured, and type-safe.

Delegate => action, as lambda
