converting a byte array to an integer

[Guest]

Hello Everyone,

How can I convert an array of bytes to an integer so for example, I have
this

a[0]= "00001010"
a[1]="11111111"
a[2]="01110011"

How can I convert this to an integer in .net

Thanks

If you indeed have byte[] then you can use BitConverter.ToInt32.

If you have strings in binary radix you will need some decoding.

Snippet:


private static string DIGITS = "0123456789ABCDEF";
private static int FromAny(string s, int radix)
{
int res = 0;
char[] sa = s.ToCharArray();
for (int i = 0; i < s.Length; i++) {
res = res * radix + DIGITS.IndexOf(sa);
}
return res;
}
public static int FromBin(string s)
{
return FromAny(s, 2);
}

This is an array of strings, not bytes. It's pretty easy to convert though:

you can use something like this function below or just use
Convert.ToInt32(a[0], 2)

private static int BinaryStringToInt(string Value)
{
int ret = 0;
for(int i = 0; i < Value.Length; i++)
{
ret <<= 1;
if(Value.Substring(i, 1) == "1") ret++;
}
return ret;
}

As these are binary strings, I'd simply use
Convert.ToInt32("00001010", 2).
