Need some help converting VB.NET code to C#

Question

I have a CRC class written in VB.NET. I need it in C#. I used an online converter to get me started, but I am getting some errors.

byte[] buffer = new byte[BUFFER_SIZE];
iLookup = (crc32Result & 0xff) ^ buffer(i);

On that line, the compiler gives me this error:

Compiler Error Message: CS0118: 'buffer' is a 'variable' but is used like a 'method'

Any ideas how I could fix this?

Thanks!

Answer 1

Change buffer(i) to buffer[i]

Answer 2

Change buffer(i) to buffer[i] as VB array descriptors are () and C# array descriptors are [].

Answer 3

Use brackets instead of parentheses.

iLookup = (crc32Result & 0xff) ^ buffer[i];

Answer 4

buffer[i];  //not buffer(i)

you used parenthesis instead of brackets.

Answer 5

You need square brackets instead of round ones at the end of the second line.

^ buffer[i];

Answer 6

You want to change the () to []. Array indexing in C# is done using square brackets, not parentheses.

So

iLookup = (crc32Result & 0xff) ^ buffer[i];

Answer 7

it should be

iLookup = (crc32Result & 0xff) ^ buffer**[i]**

Answer 8

I assume there are some lines missing between these two? Otherwise, you are always going to be doing an XOR with zero...

"buffer" is a byte array, and is accessed with the square brackets in C#. "buffer(i);" looks to the C# compiler like a method call, and it knows you have declared it as a variable. Try "buffer[i];" instead.
