What have you tried, so far? To define simple I must refer to C++ (I really hope it's OK because I am trying to learn these languages at the same time). In C++ you only use cin to store a character in a char variable, then implicitly typecast the char to an int. The version I am using right now in C# is too complex in my opinion: CODE Console.WriteLine("Please enter a character:"); string input = Console.ReadLine(); uint i; foreach (char c in input) { i = Convert.ToUInt32(c); System.Console.WriteLine("{0}'s ASCII integer value is {1}.", c, i); } First of all, it utilizes a string that is "broken down" into its char components which are then converted to integers. I am looking for a procedure similar to the one described above in C++. This post has been edited by Zeddicus: 16 Aug, 2008 - 02:18 PM

Should you use it in a special way in order to assign the value to a char? And if I do a explicit typecast like (char) Console.ReadKey, the application throws an exception.

Try:

csharp

Console.WriteLine("Please enter a character:");
uint charInt = 0;

while ((charInt = (uint)Console.Read()) != 13)
{
       System.Console.WriteLine("{0}'s ASCII integer value is {1}.", (char)charInt, charInt);
}
