C# bitwise rotate left and rotate right

Question

What is the C# equivalent (.NET 2.0) of _rotl and _rotr from C++?

Answer 1

// if you are using string

string str=Convert.ToString(number,2);

str=str.PadLeft(32,'0');




//Rotate right


str = str.PadLeft(33, str[str.Length - 1]);

str= str.Remove(str.Length - 1);

number=Convert.ToInt32(str,2);



//Rotate left


str = str.PadRight(33, str[0]);

str= str.Remove(0,1);

number=Convert.ToInt32(str,2);
