![]() ![]() ![]() But how can we know that without doing this experiment? We can therefore deduce that point1 and point2 each contain their own copy of a Point object, whereas pen1 and pen2 contain references to the same Pen object. For example: Point point1 = new Point(20, 30) Ĭonsole.WriteLine(point1.X) // 20 (does this surprise you?)Ĭonsole.WriteLine(pen1.Color) // Blue (or does this surprise you?)Īs you can see, both the Point and Pen objects were created the exact same way, but the value of point1 remained unchanged when a new X coordinate value was assigned to point2, whereas the value of pen1 was modified when a new color was assigned to pen2. Reference type, you could run into some surprises. If you don’t know whether the object you’re using is a value type or “gotcha” for those trying to learn C# programming. Instantiates the object and assigns it to a variable. Made by the programmer who wrote the object, not by the programmer who In C Sharp programming, however, that decision is Programmers of C++, and many other languages, are accustomed to being inĬontrol of whether the values they assign to variables are simply values Common C# Programming Mistake #1: Using a reference like a value or vice versa While most of the mistakes discussed in this article are C# specific, some are also relevant to other languages that target the CLR or make use of the Framework Class Library (FCL). This tutorial describes 10 of the most common C# programming mistakes made, or problems to be avoided, by C# programmers and provide them with help. However, a lot of C# coders unwittingly (or carelessly) throwĪway the benefits of this detection, which leads to some of the issuesĭiscussed in this C# tutorial. Place in languages which are more liberal with their enforcement of type This can save a lot of time in C Sharp programming, compared to tracking down the cause of puzzling errors which can occur long after the offending operation takes Their locations pinpointed quite accurately.
