Return multiple values from a method C# with Example

Tuples can be used to return multiple values from a method without using out parameters. In the following 
example AddMultiply is used to return two values (sum, product). 
void Write() 
{ 
var result = AddMultiply(25, 28); 
Console.WriteLine(result.Item1); 
Console.WriteLine(result.Item2); 
} 
Tuple AddMultiply(int a, int b) 
{ 
return new Tuple(a + b, a * b); 
} 
Output: 
53 
700 
Now C# 7.0 offers an alternative way to return multiple values from methods using value tuples More info about 
ValueTuple struct.
