示例1: Main
//引入命名空間
using System;
public class ByteConversion
{
public static void Main()
{
string[] byteStrings = { null, string.Empty, "1024",
"100.1", "100", "+100", "-100",
"000000000000000100", "00,100",
" 20 ", "FF", "0x1F" };
foreach (var byteString in byteStrings)
{
CallTryParse(byteString);
}
}
private static void CallTryParse(string stringToConvert)
{
byte byteValue;
bool success = Byte.TryParse(stringToConvert, out byteValue);
if (success)
{
Console.WriteLine("Converted '{0}' to {1}",
stringToConvert, byteValue);
}
else
{
Console.WriteLine("Attempted conversion of '{0}' failed.",
stringToConvert);
}
}
}輸出：
