示例1: foreach
string[] numericStrings = {"-3.6", "12.8", "+16.7", " 3 ", "(17)",
"-17", "+12", "18-", "987", "1,024", " 127 "};
sbyte number;
foreach (string numericString in numericStrings)
{
if (sbyte.TryParse(numericString, out number))
Console.WriteLine("Converted '{0}' to {1}.", numericString, number);
else
Console.WriteLine("Cannot convert '{0}' to an SByte.", numericString);
}输出：
Cannot convert '-3.6' to an SByte. Cannot convert '12.8' to an SByte. Cannot convert '+16.7' to an SByte. Converted ' 3 ' to 3. Cannot convert '(17)' to an SByte. Converted '-17' to -17. Converted '+12' to 12. Cannot convert '18-' to an SByte. Cannot convert '987' to an SByte. Cannot convert '1,024' to an SByte. Converted ' 127 ' to 127.
