Gotcha: use parentheses around ternary op conditional expressions

Just came across the following case in C# that puzzled me momentarily, especially since the strings involved were long enough and the expression was broken on multiple lines: bool flag = true; string test1 = flag? "xa" : "xb"; string test2 = "x" + (flag? "a" : "b"); string test3 = "x" + flag? "a" […]

Suggestion: on Duck Typing and C#/.NET

My comment at: http://visualstudio.uservoice.com/forums/121579-visual-studio-2015/suggestions/4272089-support-implicit-interfaces-for-code-reuse It would be nice indeed if one could define at the client object’s side a static interface that is a subset of the methods of a server (or serving if you prefer) object (it is only the view of the server that the client has gained knowledge of) that has been […]

Suggestion: Add support for constants in C# (and VB.net etc.) interfaces

It is rather unfortunate that C# doesn’t support constants in interfaces, whereas Java does. If IL (intermediate language) that C# usually compiles to (when not using AOT that is like in .NET Native or Xamarin iOS) doesn’t support this, then the compiler could create a special sealed class to carry the constants. Then, wherever they’re […]

Suggestion: Define once and reuse result type of method inside its body

It would be nice if one could rewrite this C# snippet: public SortedDictionary<string, UObject> GetObjects() {   SortedDictionary<string, UObject> result = new SortedDictionary<string, UObject>();   using (ReadTransaction xact = namingSchema.ReadTransaction())     foreach (ObjectName.RowType row in ObjectName.object_name_(xact))       result.Add(row.name_, row.object_);   return result; }   in a more concise form like:   public T GetObjects() where T=SortedDictionary<string, UObject> {   T result […]

Suggestion: Allow new in C# without giving Type

This is a suggestion I’ve just sent in via Visual Studio’s “Send a frown” feature: Instead of writing statements like:   List<CultureInfo> result = new List<CultureInfo>(); in C# I’d prefer to be able to write   List<CultureInfo> result = new (); inside the () one would be able to pass contructor parameters and also they […]
