.NET C# Tip- Use tuple to return multiple values

As we know tuple is a lightweight data structure. Here we’ll discuss one use case for using tuples.

When we want to return more than one value instead of out parameter, we can use a tuple.

Note: If we have to return multiple values, then we should return a single entity (view model) that has all the return values as properties.

Let us jump to an example.

public class TupleExample
    {
        public (string field1, string field2) FindMethod()
        {            
            string field1 = string.Empty;
            string field2 = string.Empty;

            //There is some logic to get details and return field1 and field2
            field1 = "field1".
            field2 = "field2".
            return (field1, field2).
        }
    }


TupleExample tupleExample = new TupleExample().
var returnValue = tupleExample.FindMethod().
Console.WriteLine($"Use Tuple to return multiple values. \n Return value1- {returnValue.field1}  \n Return value2- {returnValue.field2}");

Output
