Quickly convert Comma Separated Values to Dictionary


If you are getting some sort of CSV let’s say some sort of configurations or data object or whatever the case may be, my strategy is : “If you can not deserialize ’em, structure ’em !”

And here is one of the possible scenario :

TIP :

If you’re dealing with more complex scenario, you might wanna consider using Tuple or Jagged Tuple ! ( What is it ? )

using System;
using System.Collections.Generic;
namespace ConsoleApplication1
{

  class Program
  {
    static void Main(string[] args)
    {

      //assuming the string is well formatted and follows the constraints
      //this string may be a function parameter

      string strCommaSeparatedKeyValueString = "key1=value1,key2=value2,key3=value3,key4=value4,key5=value5";

      //init
      Dictionary<string, string> paramDict = new Dictionary<string, string>();
      string key = "", val = "";

      foreach (string keyval in strCommaSeparatedKeyValueString.Split(','))
      {
        if (!string.IsNullOrEmpty(keyval) && keyval.IndexOf('=') != -1)
        {
          key = keyval.Substring(0, keyval.IndexOf("="));
          val = keyval.Substring(keyval.IndexOf("="), (keyval.Length - keyval.IndexOf("="))).Replace("=", "");
          paramDict.Add(key, val);
          Console.WriteLine("{0} ---> {1}", key, paramDict[key]);
        }
      }
    }
  }
}
