ER! most C# people can read and write VB.NET code, I'm one of them. Why can't you guys learn C#?

For ppl like us, VB.NET and C# differs in the same way as it potato differs in American and English accent...

Looking and VB.NET and C# code everyday, I forgot the difference between the two already... Tongue Tied [:S]

The difference? Consider a very simple logic to take in two numbers and compare them. Witness the resulting IL from the different compilers.

C#
.namespace CompareNumbersCSharp
{
  .class private auto ansi beforefieldinit Class1
         extends [mscorlib]System.Object
  {
    .method private hidebysig static void
            Main(string[] args) cil managed

      // Code size       68 (0x44)
      .maxstack  2
      .locals init (int32 V_0,
               int32 V_1)
      IL_0000:  ldstr      "Enter first number: "

      IL_0038:  ret

      IL_0039:  ldstr      "Second number greater."
      IL_003e:  call       void [mscorlib]System.Console::WriteLine(string)
      IL_0043:  ret
    } // end of method Class1::Main

VB

Anybody care to explain why the VB compiler, for such a simple operation, likes to box the int32 into an object reference rather than just referring to the primitive type itself?

how did you declare the variables to store the first number and second number?

Ah, I never assume that VB.NET programers can't read and write C# code. Would that go against my profession because I used to write VB code myself? I just point out to those who don't like C# and never want to learn it. To me, they are both the same family and it's always good to at least understand the other. I have to sometimes read Java code and its design and architecture which I find extremely useful in the opposite world. The more language we know, the better there is.

There are many ways to emit out the same exact IL with VB.NET as well as C#. It is just that VB.NET carries a lot of legacy weight with it and it has to appeal for the VB6 folks to move forward, thats why there are some idiosyncrancies to deal with.

If VB.NET could start on the same footing as C#, this legacy would all disappear

Just want to make some wild guess, does option strict/explicit have any impact on the IL?
Also, in VB, does Integer, Int16, Int32 make any difference?
How about this.... run the Reflector on the compiled C# and see what is the VB.NET equivalent.
