Keterangan
Nilai numerik adalah properti karakter Unicode yang hanya berlaku untuk karakter numerik, yang mencakup pecahan, subskrip, superskrip, angka Romawi, pembilang mata uang, angka yang dilingkari, dan digit khusus skrip. Untuk informasi selengkapnya tentang karakter Unicode, lihat Standar Unicode.
Metode ini GetNumericValue(Char) mengasumsikan bahwa ch
sesuai dengan satu karakter linguistik dan memeriksa apakah karakter tersebut dapat dikonversi menjadi digit desimal. Namun, beberapa angka dalam standar Unicode diwakili oleh dua Char objek yang membentuk pasangan pengganti. Misalnya, sistem penomoran Aegean terdiri dari titik kode U+10107 hingga U+10133. Contoh berikut menggunakan ConvertFromUtf32 metode untuk membuat instans string yang mewakili AEGEAN NUMBER ONE. Seperti yang ditunjukkan oleh output dari contoh, GetNumericValue(Char) metode mengembalikan -1 jika diteruskan baik pengganti tinggi atau pengganti rendah karakter ini.
int utf32 = 0x10107; // AEGEAN NUMBER ONE
string surrogate = Char.ConvertFromUtf32(utf32);
foreach (var ch in surrogate)
Console.WriteLine($"U+{(ushort)ch:X4}: {System.Globalization.CharUnicodeInfo.GetNumericValue(ch)} ");
// The example displays the following output:
// U+D800: -1
// U+DD07: -1
Dim utf32 As Integer = &h10107 ' AEGEAN NUMBER ONE
Dim surrogate As String = Char.ConvertFromUtf32(utf32)
For Each ch In surrogate
Console.WriteLine("U+{0:X4}: {1} ", Convert.ToUInt16(ch),
System.Globalization.CharUnicodeInfo.GetNumericValue(ch))
Next
' The example displays the following output:
' U+D800: -1

Char Jika objek pada posisi index
adalah karakter pertama dari pasangan pengganti yang valid, GetNumericValue(String, Int32) metode menentukan apakah pasangan pengganti membentuk digit numerik, dan, jika ya, mengembalikan nilai numeriknya. Misalnya, sistem penomoran Aegean terdiri dari titik kode U+10107 hingga U+10133. Contoh berikut menggunakan metode untuk membuat instans ConvertFromUtf32 string yang mewakili setiap angka Aegean. Seperti yang ditunjukkan oleh output dari contoh, GetNumericValue(String, Int32) metode mengembalikan nilai numerik yang benar jika diteruskan sebagai pengganti tinggi dari angka Aegean. Namun, jika melewati pengganti rendah, itu hanya menganggap pengganti rendah dalam isolasi dan mengembalikan -1.
// 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,
System.Globalization.CharUnicodeInfo.GetNumericValue(surrogate, ctr));
Console.WriteLine();
