Generate GUID using 2 digit State Code
-
I am getting problem in generating new GUID using its constructor who takes one string argument. like this Guid regionID = new Guid(this.State.SelectedValue); state gives 2 digit state code.The error says you need 32 digit with 4 dashes string to generate GUID. any solutions ? Amit Champaneri

That's right, because GUID is basically 16 bytes separated in certain places by 4 dashes... You can not have GUID with only two bytes. If you want, you can do it like this:
byte[] guidBytes = new byte[16]; Random rand = new Random(); rand.NextBytes(quidBytes); guidBites[0] = Convert.ToByte(this.State.SelectedValue[0]); guidBites[1] = Convert.ToByte(this.State.SelectedValue[1]); Guid myGuid = new Guid(guidBytes);this should works Pilo -

I think you are confused about what a GUID actually is. A Guid is a value that is generated by the system to be Globally (as in the world) unique. You should be able to generate as many guid values as you like on your machine and so could everyone else, but every value would always be unique.

You need to try to look at the bigger picture when answering questions because most are asking questions because they've got themselves in to a bit of confusion about something. Subsequently they may not ask the best question to get the answer they need.
