Casting question

[AMP]

Hello,
I have:
ushort length= 4;
ushort len;
And I get an error here:
length = len + 4;

Error 6 Cannot implicitly convert type 'int' to 'ushort'. An explicit
conversion exists (are you missing a cast?)

Thanks Mike

Try:

length = (ushort)(len + 4);

Basically, there's no operator which adds two ushorts together - they
just get promoted to ints and then the addition is performed, resulting
in an int.

You'll need to cast the result, as Arne says.

However, if you can use += instead, you don't need the extra cast:

ushort x = 5;
ushort y = 10;

x += y;
