Gotcha: use parentheses around ternary op conditional expressions
25 Αυγούστου 18 03:42 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

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
16 Νοεμβρίου 15 12:52 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

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
23 Αυγούστου 15 01:12 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

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 […]

HowTo: Call C# method from class that has same name as namespace
06 Ιουλίου 14 03:25 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

In the C# compiler error case shown above, CaptionsGrid class exists in namespace ClipFlair.CaptionsGrid so in the code we have “using ClipFlair.CaptionsGrid;” at the top of the file where we want to call the “SaveAudio” static method of CaptionsGrid class. But then we get the error “The type or namespace name ‘…’ does not exist […]
