Question

i tried converting this code from c#

a += (uint)(url[k + 0] + (url[k + 1] << 8) + (url[k + 2] << 16) + (url[k + 3] << 24));

to vb,net i get this

a += CUInt(url(k + 0) + (url(k + 1) << 8) + (url(k + 2) << 16) + (url(k + 3) << 24))

an i get this error

Operator ‘<<‘ is not defined for types ‘Char’ and ‘Integer’.

Can anyone help me with a correction

EDIT

uint a, b;

a = b = 0x9E3779B9;

url = string

Answer 1

Your main problem seems to be that C# will allow bit-shifting on a char whereas VB does not.

So you would need something like (untested)

 CUInt( ... + (CUint( url(k + 1) ) << 8) + ... )

But it does look like a rather weak HashCode.
