[RESOLVED] Some small doubts while reading other posts

[akhileshbc]

Hi..

While I was reading some posts, I got stuck at certain lines.

1. Public Class IP_ADAPTER_INFO
       Public [Next] As IntPtr
   '......

   Why the square brackets ?

2. Dim Count As Integer = RichTextBox.Text.Split(","c).Length

   What's the use of character c in above code?

Thanks...

Edit:
Ooops. I posted in the wrong section

1. they are used to tell the compiler that these are not the predefined words but user defined variables

2. to conver the string into character

Yes, Next is predefined, a for-Next loop would be very sorry without it

For <some statement>
'//method body
Next

Ah! Didn't thought about that one

I was trying to migrate from VB6 to .Net. So, before that I flushed my memory.

Sorry for my stupid question.

As said, square brackets allow you to use a name (for methods, variables, properties, etc) that is usually reserved for keywords. Other examples are Public, Private, Class, Sub, etc.

As for your second point, the c indicates that it is a character literal and not a string literal of length 1. Even though a character and a 1-letter string are in all usual senses the same, in .NET they are simply two different classes. I would like to correct aashish_9601's answer though: there is no conversion taking place.

Dim a = "x"
Dim b = "x"c

In this code, a is a String and b is a Char.
The C# equivalent would be

var a = "x";
var b = 'x';

Since ' is reserved for comments in VB they had to find a different way to distinguish string and char literals, and they chose for a 'c' suffix.
