示例1: foreach
string[] numericStrings = { "1293.8", "+1671.7", "28347.",
" 33113684 ", "(0)", "-0", "+1293617",
"18-", "119870", "31,024", " 3127094 ",
"00700000" };
ulong number;
foreach (string numericString in numericStrings)
{
if (UInt64.TryParse(numericString, out number))
Console.WriteLine("Converted '{0}' to {1}.", numericString, number);
else
Console.WriteLine("Cannot convert '{0}' to a UInt64.", numericString);
}输出：
Cannot convert '1293.8' to a UInt64. Cannot convert '+1671.7' to a UInt64. Cannot convert '28347.' to a UInt64. Converted ' 33113684 ' to 33113684. Cannot convert '(0)' to a UInt64. Converted '-0' to 0. Converted '+1293617' to 1293617. Cannot convert '18-' to a UInt64. Converted '119870' to 119870. Cannot convert '31,024' to a UInt64. Converted ' 3127094 ' to 3127094. Converted '0070000' to 70000.
