Exceptions
| Exception | Condition |
|---|---|
| FormatException | format includes an unsupported specifier. Supported format specifiers are listed in the Remarks section. |
Remarks
The format parameter can be either a standard or a custom numeric format string. All standard numeric format strings other than "R" (or "r") are supported, as are all custom numeric format characters. If format is nulla null reference (Nothing in Visual Basic) or an empty string (""), the return value of this method is formatted with the general numeric format specifier ("G").
The provider parameter is an object that implements the IFormatProvider interface. Its GetFormat method returns a NumberFormatInfo object that provides culture-specific information about the format of the string that is returned by this method. The object that implements IFormatProvider can be any of the following:
A CultureInfo object that represents the culture whose formatting rules are to be used.
A NumberFormatInfo object that contains specific numeric formatting information for this value.
A custom object that implements IFormatProvider.
If provider is nulla null reference (Nothing in Visual Basic) or a NumberFormatInfo object cannot be obtained from provider, the return value is formatted using the NumberFormatInfo object for the thread current culture. For information about the thread current culture, see Thread.CurrentCulture.
The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

Examples
The following example uses the standard "N" format string and four different CultureInfo objects to display the string representation of a byte value to the console.
Dim byteValue As Byte = 250
Dim providers() As CultureInfo = {New CultureInfo("en-us"), _
New CultureInfo("fr-fr"), _
New CultureInfo("es-es"), _
New CultureInfo("de-de")}
For Each provider As CultureInfo In providers
outputBlock.Text &= String.Format("{0} ({1}) & vbCrLf", _
byteValue.ToString("N2", provider), provider.Name)
Next
' The example displays the following output:
' 250.00 (en-US)
' 250,00 (fr-FR)
' 250,00 (es-ES)
' 250,00 (de-DE)
byte byteValue = 250;
CultureInfo[] providers = {new CultureInfo("en-us"),
new CultureInfo("fr-fr"),
new CultureInfo("es-es"),
new CultureInfo("de-de")};
foreach (CultureInfo provider in providers)
outputBlock.Text += String.Format("{0} ({1})",
byteValue.ToString("N2", provider), provider.Name) + "\n";
// The example displays the following output:
// 250.00 (en-US)
// 250,00 (fr-FR)
// 250,00 (es-ES)
// 250,00 (de-DE)
