    Hey Guys, I have a string consisting of zeros and ones like 10101010 I want to read each letter then convert it to code and use it ... I've checked the function Split() but it requires a character, and as u see mine doesn't have any. Regards, K

      Just use - ToCharArray()

      string strTest = "1100110101";
      char[] cList = strTest.ToCharArray();

        Try using the Substring method of a string.

          Hi Abhinav, Isn't string.ToCharArray() a better way than using string.SubString()?

          Thanks, Ram

            This is okay unless you don't want to allocate more memory in the process. Using string.Substring() would be a viable alternative. (I still marked your response as a "good answer". :) )

              I have to ask - what does the string represent? A series of flags? If so, you could convert it to an integer, and then access it with logical AND (&) and logical OR (|) operators. Math operations are always faster/more efficient than string operations. To convert the string to an int, do this:

              string myString = "10101010";
              int flags = Convert.ToInt32(myString, 2);

              At that point, you can do this:

              int myVal = 4;
              if ((myVal & flags) == myVal)
              {
              // do something if 4 is a set value
              }

                I have access to each character of my string ! :D each character is a code, I'm trying to store days for a class so for instance its 1000000, it means its only Saturday, or 1010100 means it's on Saturday, Monday and Wednesday. Regards, K

                      Well, then you can do that more cleanly if you want...

                      [Flags]
                      public enum DayFlags
                      {
                      Saturday = 64,
                      Sunday = 32,
                      Monday = 16,
                      Tuesday = 8,
                      Wednesday = 4,
                      Thursday = 2,
                      Friday = 1
                      }

                      public static bool IsFlagSet(this DayFlags en, DayFlags flag)
                      {
                      return ((int)en & (int)flag) != 0;
                      }

                      DayFlags days = (DayFlags)Convert.ToInt32(str, 2);

                      if (days.IsFlagSet(DayFlags.Sunday)) { ... }
