Solution 1

try like this

JavaScript

$.ajax({
           type: "POST",
           url: './ControllerName/ActionName',
           data: {},
           dataType: "json",
           async: true,
           success: function (result) {
               alert(result);
           }
       });

Very very simple

if you have paste this code in home controller and ur iis is listening as http://localhost:54371 then it is

http://localhost:54371/Home/ReverseTheString/?input=test

interesting if you put a null string check like follows

public string ReverseTheString(string input)
      {
          if (string.IsNullOrWhiteSpace(input))
          {
              return "string is empty";
          }
          char[] arr = input.ToCharArray();
          System.Array.Reverse(arr);
          return new string(arr);
      }

then try this too

http://localhost:58455/Home/ReverseTheString/test

for multiple

public string ReverseTheString(string input, string input2, int age)
      {
          if (string.IsNullOrWhiteSpace(input))
          {
              return "string is empty";
          }
          char[] arr = input.ToCharArray();
          System.Array.Reverse(arr);
          return new string(arr);
      }

http://localhost:58455/Home/ReverseTheString/?input=first&input2=2nd&age=3
