示例1: Main
//引入命名空間
using System;
public class GetNumericValueSample {
public static void Main() {
string str = "input: 1";
Console.WriteLine(Char.GetNumericValue('8')); // Output: "8"
Console.WriteLine(Char.GetNumericValue(str, 7)); // Output: "1"
}
}示例2: for
// Define a UTF32 value for each character in the
// Aegean numbering system.
for (int utf32 = 0x10107; utf32 <= 0x10133; utf32++) {
string surrogate = Char.ConvertFromUtf32(utf32);
for (int ctr = 0; ctr < surrogate.Length; ctr++)
Console.Write("U+{0:X4} at position {1}: {2} ",
Convert.ToUInt16(surrogate[ctr]), ctr,
Char.GetNumericValue(surrogate, ctr));
Console.WriteLine();
}輸出：
