vb.net-to-c#

(this is related to this other question ) If you define an Interface where there is a Property with only a getter (= ReadOnly in VB.NET), why can you define the setter in implementing classes with C# but not with VB ? I would have thought it was defined at .NET level, and not language-specific. Example: for this interface 'VB.NET Interface SomeInterface 'the interface only say that implementers must provide a value for reading ReadOnly Property PublicProperty As String End Interface or //C# code interface IPublicProperty { string PublicProperty { get; } } This is a correct implementation in C#

In VB.NET I often Catch…When : Try … Catch e As ArgumentNullException When e.ParamName.ToUpper() = "SAMPLES" … End Try Is there a C# equivalent to Catch…When ? I don't want to resort to using an if statement inside a catch if possible. This functionality was announced for C# 6. It is now possible to write try { … } catch (MyException e) when (myfilter(e)) { … } You can download the preview of Visual Studio 2015 now to check this out, or wait for the official release. cruizer There's no equivalent to Catch…When in C#. You will really have to resort to an if statement inside your catch , then

I am trying to convert the example provided in MSDN article Creating Dynamic Data Entry User Interfaces to C#, but am stuck at the following code: CType(dq, IUIBuildingBlock).QuestionText = reader("QuestionText") How do I convert the above VB.NET statement to C#? In C#, you can specify a cast by putting the type you want to cast to in parenthesis in front of the reference variable that you want to cast ( (type)instance ). So, to cast the object ( dq ) to the type IUIBuildingBlock , you could use the following code: ((IUIBuildingBlock)dq).QuestionText = reader("QuestionText"); (Note that this

I'm working on becoming as familiar with C# as I am with VB.NET (the language used at my workplace). One of the best things about the learning process is that by learning about the other language you tend to learn more about your primary language--little questions like this pop up: According to the sources I've found, and past experience, a field in VB.NET that is declared as WithEvents is capable of raising events. I understand that C# doesn't have a direct equivalent--but my question is: fields without this keyword in VB.NET cannot raise events, is there a way to create this same behavior in

Which are the equivalent of the following operators from VB.Net to C#?
