How can i get the numeric representation of a string in C#? To be clear, I do not want the address of the pointer, I do not want to parse an int from a string, I want the numeric representation of the value of the string.
The reason I want this is because I am trying to generate a hash code based on a file path (path) and a number (line). I essentially want to do this:
String path;
int line;
public override int GetHashCode() {
return line ^ (int)path;
}
I'm up to suggestions for a better method, but because I'm overriding the Equals() method for the type I'm creating (to check that both object's path and line are the same), I need to reflect that in the override of GetHashCode.
Edit: Obviously this method is bad, that has been pointed out to me and I get that. The answer below is perfect. However, it does not entirely answer my question. I still am curious if there is a simple way to get an integer representation of the value of a string. I know that I could iterate through the string, add the binary representation of that char to a StringBuffer and convert that string to an int, but is there a more clean way?
Edit 2: I'm aware that this is a strange and very limited question. Converting in this method limits the size of the string to 2 chars (2 16 bit char = 1 32 bit int), but it was the concept I was getting at, and not the practicality. Essentially, the method works, regardless of how obscure and useless it may be.
If all you want is a HashCode, why not get the hashcode of the string too? Every object in .net has a GetHashCode() function:
public override int GetHashCode() {
return line ^ path.GetHashCode();
}
