Would this need to be dynamically capable so that Hello_World could equal any size string delimited with "_"?

Spitting the string based on the "_" delimeter:

string[] splitList = "Hello_World".Split('_');

Open in new window


Re-assembling the string based on index:

string resultString = string.Format("{0}_{1}", splitList[1], splitList[0]);

Open in new window


Doing this from memory so I cant check syntax as well as usual.

Try This, a bit of linq but worthy the solution, Now your text can be dynamic:-
            string value = "Hello_World_Test_Test1_test2";
            var arrStrings = value.Split('_').Reverse().ToArray();

            Console.WriteLine(string.Join("_", arrStrings));

Open in new window
