Problem with byte Array compare

Hi

I have two byte arrays (each with a length of 8 bytes)
an I'd like to compare them if they are equal.

The operator == shouldn't work because its not a basic Data Type
so I used the method Equal, but it also isn't working.

right know I use
if(mykey.Length!= keytocheck.Length)
return false;
for (int i = 0; i < mykey.Length; i++)
{
if (mykey != keytocheck)
return false;
}

This is working, but why I cannot use the Equal method??
Can somebody explain it to me?

regards
Norbert
 
Norbert,

Quite simply, the Equals method is not overridden to provide the
semantics you desire. You will have to perform this check, or wrap it in a
utility method if this is the result you desire.

Hope this helps.

Well, if == had been overloaded for byte arrays, that would still work
just fine.
so I used the method Equal, but it also isn't working.

right know I use
if(mykey.Length!= keytocheck.Length)
return false;
for (int i = 0; i < mykey.Length; i++)
{
if (mykey != keytocheck)

}

Because Equals hasn't been overridden to compare arrays. The above
looks fine though.
