C# & Databases - Creating a unique identifer
Creating a new GUID in C# is not as straightforward as one would think. Calling the constructor of System.Guid() will produce a GUID of all zeroes. Using System.Guid.NewGuid() will produce the desired effect of a new, unique identifier.
1 2 // produces a "blank" GUID: '00000000-0000-0000-0000-000000000000' 3 System.Guid blankGuid = new System.Guid(); 4 5 // produces a new, unique GUID: '96d36892-6eed-400c-91f8-a194f3522fae' 6 System.Guid desiredGuid = System.Guid.NewGuid();
