Getting The ASCII Value of a character in a C# string

Question

Consider the string:

string str="A C# string"; 

What would be most efficient way to printout the ASCII value of each character in str using C#.

Answer 1

Just cast each character to an int:

for (int i = 0; i < str.length; i++)     Console.Write(((int)str[i]).ToString()); 

Answer 2

Here's an alternative since you don't like the cast to int:

foreach(byte b in System.Text.Encoding.UTF8.GetBytes(str.ToCharArray()))     Console.Write(b.ToString());
