How to implement switch statement in C# ?

A switch statement in C, C#, and C++ allows you to execute different code blocks based on the value of a variable. It evaluates an expression and compares its value to a series of constant cases. If a match is found, the corresponding code block is executed. If no case matches, the optional 'default' case is executed. This provides a structured and efficient way to handle multiple possible outcomes, often replacing a series of if-else statements.
 

Switch statement executes a set of logic depending on the value of a given parameter.

The types of the values a switch statement operates on can be booleans, enums, integral types, and strings.

Following is the example.

switch( strName)
{
  case "james":  strResult="male"; break;
  case "jane": strResult="female"; break;
  default: strResult = "unkonwn"; break;
}
