the string "if (arg2 and 1)" in C ++ (arg2 - DWORD) is equal to "if (arg2 and 1 == 0)" in C # (arg2 - Uint32), right?
I am trying to translate a function from C ++ to C #, but I get an error:
Operator '&' cannot be applied to operands of type 'uint' and 'bool'
I would also be grateful if you could see further the whole function for any other errors.
C ++
DWORD Func_X_4(DWORD arg1, DWORD arg2, DWORD arg3)
{
LARGE_INTEGER result = {1, 0};
LARGE_INTEGER temp1 = {0};
LARGE_INTEGER temp2 = {0};
LARGE_INTEGER temp3 = {0};
LARGE_INTEGER temp4 = {0};
for(int x = 0; x < 32; ++x)
{
if(arg2 & 1)
{
temp1.LowPart = arg3;
temp1.HighPart = 0;
temp2.QuadPart = temp1.QuadPart * result.QuadPart;
temp3.LowPart = arg1;
temp3.HighPart = 0;
temp4.QuadPart = temp2.QuadPart % temp3.QuadPart;
result.QuadPart = temp4.QuadPart;
}
arg2 >>= 1;
temp1.LowPart = arg3;
temp1.HighPart = 0;
temp1.QuadPart *= temp1.QuadPart;
temp2.LowPart = arg1;
temp2.HighPart = 0;
temp3.QuadPart = temp1.QuadPart % temp2.QuadPart;
arg3 = temp3.LowPart;
if(!arg2)
break;
}
return result.LowPart;
}
Converted to C #
LARGE_INTEGER structure:
[StructLayout(LayoutKind.Explicit, Size = 8)]
public struct LARGE_INTEGER
{
[FieldOffset(0)]
public Int64 QuadPart;
[FieldOffset(0)]
public UInt32 LowPart;
[FieldOffset(4)]
public Int32 HighPart;
}
Functions:
public static UInt32 X4(UInt32 arg1, UInt32 arg2, UInt32 arg3)
{
LARGE_INTEGER result = new LARGE_INTEGER();
result.LowPart = 1;
result.HighPart = 0;
LARGE_INTEGER temp1 = new LARGE_INTEGER();
LARGE_INTEGER temp2 = new LARGE_INTEGER();
LARGE_INTEGER temp3 = new LARGE_INTEGER();
LARGE_INTEGER temp4 = new LARGE_INTEGER();
for (int x = 0; x < 32; ++x)
{
if (arg1 & 1 ==0)
{
temp1.LowPart = arg3;
temp1.HighPart = 0;
temp2.QuadPart = temp1.QuadPart * result.QuadPart;
temp3.LowPart = arg1;
temp3.HighPart = 0;
temp4.QuadPart = temp2.QuadPart % temp3.QuadPart;
result.QuadPart = temp4.QuadPart;
}
arg2 >>= 1;
temp1.LowPart = arg3;
temp1.HighPart = 0;
temp1.QuadPart *= temp1.QuadPart;
temp2.LowPart = arg1;
temp2.HighPart = 0;
temp3.QuadPart = temp1.QuadPart % temp2.QuadPart;
arg3 = temp3.LowPart;
if (arg2==0)
break;
}
return result.LowPart;
}
This is what I'm not sure yet:
- Is DWORD in C ++ UInt32 or Int32 in C #?
- if (integer and integer) means if (integer and integer == 0)? // the error described above is placed here.
- if (! integer) means if (integer! = 0)?
- Why can't an operator be used logically in C #, that is, it requires a logical one?
- "LARGE_INTEGER result = {1, 0}" result.lowpart 1 result.highpart 0 result.Quadpart = 1?
