GetType() and Typeof() in C#

Question

itemVal = \"0\";

res = int.TryParse(itemVal, out num);

if ((res == true) && (num.GetType() == typeof(byte)))  
    return true;
else
   return false;  // goes          


        

Answer 1

Simply because you are comparing a byte with an int

If you want to know number of bytes try this simple snippet:

int i = 123456;
Int64 j = 123456;
byte[] bytesi = BitConverter.GetBytes(i);
byte[] bytesj = BitConverter.GetBytes(j);
Console.WriteLine(bytesi.Length);
Console.WriteLine(bytesj.Length);

Output:

4
8
