C Sharp Programming/Keywords/else

Keywords else __TOC__ The else keyword identifies a else clause of an if statement with the following syntax: if-statement ::= "if" "(" condition ")" if-body "else" else-body condition ::= boolean-expression if-body ::= statement-or-statement-block else-body ::= statement-or-statement-block An else clause immediately follows an if-body. It provides code to execute when the condition is false. Making the else-body another if statement creates the common cascade of if, else if, else if, else if, else statements: using System; public class IfStatementSample { public void IfMyNumberIs() { int myNumber = 5; if (myNumber == 4) Console.WriteLine("This will not be shown because myNumber is not 4."); else if(myNumber < 0) { Console.WriteLine("This will not be shown because myNumber is not negative."); } else if(myNumber%2 == 0) Console.WriteLine("This will not be shown because myNumber is not even."); else { Console.WriteLine("myNumber does not match the coded conditions, so this sentence will be shown!"); } } } The above example only checks whether myNumber is less than 0, if myNumber is not 4. It in turn only checks whether myNumber%2 is 0, if myNumber is not less than 0. Since none of the conditions are true, it executes the body of the final else clause.
