ASP.net best way to Return Multiple Values from a Function

From .NET Framework 4 Tuple class has been introduce to create combination of heterogeneous objects .Its can used to group different types of items (objects ) and indicate this group as single object.

Tuple is a class and once you create the Tuple, you cannot change the types of the items or the values assigned in the creation. This makes the Tuple more like a struct.

However this enable much safe way to return distinct number of    multiple elements to be returned for a function .

Example function(return Boolean and string )
public class Class1
    {
 public static Tuple<Boolean, String> ExampleFunction(string parameterVal)
        {
  Boolean retunValue1= false;
 string retunValue2 = "";
.......
 return Tuple.Create(retunValue1, retunValue2 );

}
}



Calling Function and Retrieve return Values 



 var retTuple = Class1.ExampleFunction(parameterVal);

          Boolean retriveValue1  =      retTuple.Item1;
         String      retriveValue2  =      retTuple.Item2;
