Decimal.ToString方法详解

Int/Decimal.ToString 方法 (String, IFormatProvider) 
decimal value = 16325.62m;
string specifier;
CultureInfo culture;

// Use standard numeric format specifiers.
specifier = "G";
culture = CultureInfo.CreateSpecificCulture("eu-ES");
Console.WriteLine(value.ToString(specifier, culture));
// Displays:    16325,62
Console.WriteLine(value.ToString(specifier, CultureInfo.InvariantCulture));
// Displays:    16325.62

specifier = "C";
culture = CultureInfo.CreateSpecificCulture("en-US");
Console.WriteLine(value.ToString(specifier, culture));
// Displays:    $16,325.62
culture = CultureInfo.CreateSpecificCulture("en-GB");
Console.WriteLine(value.ToString(specifier, culture));
// Displays:    16,325.62

specifier = "E04";
culture = CultureInfo.CreateSpecificCulture("sv-SE");
Console.WriteLine(value.ToString(specifier, culture));
// Displays: 1,6326E+004   
culture = CultureInfo.CreateSpecificCulture("en-NZ");
Console.WriteLine(value.ToString(specifier, culture));
// Displays:    1.6326E+004  

specifier = "F";
culture = CultureInfo.CreateSpecificCulture("fr-FR");
Console.WriteLine(value.ToString(specifier, culture));
// Displays:    16325,62
culture = CultureInfo.CreateSpecificCulture("en-CA");
Console.WriteLine(value.ToString(specifier, culture));
// Displays:    16325.62

specifier = "N";
culture = CultureInfo.CreateSpecificCulture("es-ES");
Console.WriteLine(value.ToString(specifier, culture));
// Displays:    16.325,62
culture = CultureInfo.CreateSpecificCulture("fr-CA");
Console.WriteLine(value.ToString(specifier, culture));
// Displays:    16325,62

specifier = "P";
culture = CultureInfo.InvariantCulture;
Console.WriteLine((value/10000).ToString(specifier, culture));
// Displays:    163.26 %
culture = CultureInfo.CreateSpecificCulture("ar-EG");
Console.WriteLine((value/10000).ToString(specifier, culture));
// Displays:    163.256 %

decimal aa = Convert.ToDecimal("99999.99999");
string bb = aa.ToString("N5");
得到 bb=9,999.99999

12345.ToString("n"); //生成 12,345.00 
12345.ToString("C"); //生成 ￥12,345.00 
12345.ToString("e"); //生成 1.234500e+004 
12345.ToString("f4"); //生成 12345.0000 
12345.ToString("x"); //生成 3039 (16进制) 
12345.ToString("p"); //生成 1,234,500.00%--摘自小明Blog.
