simple not on int or uint

[Jure Bogataj]

Hello!

Why I cannot apply this operator to UINT or INT type in c# (VS 2005)?

uint MyConst;
uint SomeValue;
....
MyConst = MyConst & (!SomeValue)

Trying to erase certain bit inside MyConst. I come from Delphi world and the
translation would be
MyConst = MyConst and (not SomeValue)
where (not SomeValues) turns bits arround (0==>1, 1==>0)

How can the same thing be accomplished in c#?

best regards,
Jure

Hi Jure,
I think you want the bitwise operator ~ . Try something like this:
uint MyConst = 255;
uint SomeValue = 2;
MyConst = MyConst & ~SomeValue;

Hi,

...
MyConst = MyConst & (!SomeValue)

I think that the operator you are looking for is ~ :

MyConst = MyConst & (~SomeValue)

I think you want "~", not "!", as per:

uint seven = 7;
uint four = 4;
uint threeihope = seven & ~four;

Console.WriteLine("result = " + threeihope);
Console.ReadLine();
