    My advice - don't change the code, and hope your "very senior developer" doesn't have a CP account.

      While comparing my changes with the server source code, just saw with my two eyes this great piece of code which checks if an nullable int is null or not :

      private bool IsHasValue(int? a)
      {
      if (a== null)
      {
      return false;
      }
      return true;
      }

      The code is written by very senior developer on my team with huge years of experience in c# :laugh:

      A consultant friend of mine who has been programming far longer than I have—he started programming on the early Macs and helped write the first music notation software for the Mac—doesn't see why C# should need to use .SubString() to get the left/right most characters from a string and instead wrote these. I don't really have a problem with this sort of thing. I just don't see the point, but that's just me.

          public string LeftStringFunction(string sValue, int iMaxLength)
          {
              //Check if the value is valid
              if (string.IsNullOrEmpty(sValue))
              {
                  //Set valid empty string as string could be null
                  sValue = string.Empty;
              }
              else if (sValue.Length > iMaxLength)
              {
                  //Make the string no longer than the max length
                  sValue = sValue.Substring(0, iMaxLength);
              }
      
              //Return the string
              return sValue;
          }
      
          public string RightStringFunction(string sValue, int iMaxLength)
          {
              //Check if the value is valid
              if (string.IsNullOrEmpty(sValue))
              {
                  //Set valid empty string as string could be null
                  sValue = string.Empty;
              }
              else if (sValue.Length > iMaxLength)
              {
                  //Make the string no longer than the max length
                  sValue = sValue.Substring(sValue.Length - iMaxLength, iMaxLength);
              }
      
              //Return the string
              return sValue;
          }

        You see that large number at the top left of this website? A large fraction of those are actually sockpuppets with John pulling the strings. Don't be surprised if the 'persona' of your senior colleague appears out of nowhere. Best Wishes, -David Delaune

          Looks like somebody's trying to reinvent VB6's Left$ and Right$, neither of which throw an exception if you specify a length that's longer than the string. :)

            Left$ would be GwBasic (not VB6 where the $s were dropped) :-)

              Not just reinventing it, but reinventing it to be less efficient. The actual HasValue implementation just checks an internal flag that's set to true when a value is assigned.

                  Well obviously checking for false (in the calling code) is so much better than checking for null. Plus, if the int isn't null (contains a value) then you get the wonderful True back and true just makes you feel good. :laugh:

                      Remimds me of the code generated by a compiler I once knew: This was in the days of the superminis, very much CISC. This machine (called ND-500) had a "LoadIndex [register] [indexvalue] [min] [max]" instruction: If the value at [indexvalue] was not between [min] and [max], a exception was generated. This compiler could (optionally) verify all array indexing, using this instruction, but not quite in the straightforward way that you might think. A disassembly showed something like this LOAD R4, indexvalue COMP R4, min JUMPLT error COMP R4, max JUMPGT error % everything is OK, go ahead ... error: LOADINDEX R4, R4, 0, -1 % no legal range, will unconditionally generate exception Generating six instructions to replace a single one can be meaningful, but hardly when one of the six is the instruction you want to replace... I was working in the company making both the CPU and the compiler, so I went to the compiler guy for an explanation. He insisted that since index check was an option, it should not change any code generated, only add code: The index check is like a debugging aid that you might turn off in a production build, and the production version should be exactly the code you debugged, minus the debug features. With the option off, the first instruciton (LOAD R4, indexvalue) was generated. Turn it on, and you get the five additional instructions. Needless to say: Even though his argument sort of sounds plausible, I strongly disagreed with him. First, index checking is not a debug feature; you keep it on in the production version. Second: Given an option set, the compiler should be free to the best code for that selection of options, ignoring other option sets (think of optimization options!) After much arguing, he agreed to rather generate LOAD R4, indexvalue LOADINDEX R4, R4, min, max ... two instructions is better than six. But he stuck to his principles: I never got him to generate a singel LOADINDEX.

                          If Right$() and Left$() make some other code easier to parse. Good for him. It seems like those should be static or some sort of extension method. What is "this" in those methods?

                            Looks like somebody's trying to reinvent VB6's Left$ and Right$, neither of which throw an exception if you specify a length that's longer than the string. :)

                              While comparing my changes with the server source code, just saw with my two eyes this great piece of code which checks if an nullable int is null or not :

                              private bool IsHasValue(int? a)
                              {
                              if (a== null)
                              {
                              return false;
                              }
                              return true;
                              }

                              The code is written by very senior developer on my team with huge years of experience in c# :laugh:

                              Does it predate the Nullable data type being added to the framework?

                                the parameter is itself a Nullable and i know this is the latest code that we are working on in .NET 4.0 using C# 6 language in it.

                                  You could consider telling the senior dev about the .HasValue property; knowledge share. Also, the correct English for "... an nullable ..." is "... a nullable ...". :)

                                    senior is aware of that, but i am not getting why this method was authored in first place :) I will discuss for sure sometime that.

                                          There's the problem right there -- they're not used to thinking of base, simple types as classes. Ask them what they think an int? is, and they'll probably tell you it's a pointer to an int. Pointers aren't classes that can have functions. Took me a while to get used to the concept too.

                                          I live in Oregon, and I'm an engineer.
