C # function returns the values of a plurality of methods

Sometimes we need a function return multiple values, use the Internet more to achieve out, I personally like to use tuple method.

tuple is a tuple, up to 7 elements, need more nesting methods.

Tuple function is defined as follows:

public static Tuple<string,string> TupleFun()
        {
            string[] T = {'hello','world'};
            Tuple<string, string> tup = new Tuple<string, string>(T[0], T[2]);
            return tup;
        }

Tuple also supports multiple types of values.

public static Tuple<string,int> TupleFun()
        {
            string T = ‘hello’;
            int q = 6;
            Tuple<string, int> tup = new Tuple<string, int>(T, q);
            return tup;
        }

When calling the function, use Item * to call the elements within the tuple.

var tuple = TupleFun();
print(tuple.Item1);
print(int.Parse(tuple.Item2));
