In VB.NET, it is entirely possible to pass an integer as a string parameter

  • 0

In VB.NET, it is entirely possible to pass an integer as a string parameter to a method without calling .ToString() – it’s even possible to call .ToString without the ()’s. The code will run without a problem, VB will interpret the integer as a string without having been told to.

In C#, these would cause compilation errors – you are required to call .ToString() and to call it correctly in that situation before it will compile.

Is there a way to make the VB compilation process check for the same things as the C# compilation process? Would it be best practice in a mixed team to force this check?

    There are several compiler options you can switch on, Option Strict will do most of what you want i.e. will not allow you to pass an integer for a string.
    You set it on the Compile tab for your projects settings, or you can just put Option Strict On at the top of a class/module file.

    However things like being able to call o.ToString instead of o.ToString() are part of the language semantics, you can’t do anything about that.

    If you REALLY want something that compiles just like C#, then you have to use C#.
    Sorry 🙁

    Hope this helps
