Parameters
- format
Type: System.String
A standard or custom numeric format string (see Remarks).

Implements
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 string returned by this method is formatted with the general numeric format specifier ("G").
The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:
For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.
For more information about formatting, see Formatting Types.
The provider parameter is an IFormatProvider implementation. 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 with the NumberFormatInfo for the current culture.
Examples
The following example displays an Int16 value using each of the supported standard format strings in four different cultures.
Dim value As Int16 = 14603
Dim formats() As String = {"C", "D6", "e1", "E2", "F1", "G", "N1", _
"P0", "X4", "000000.0000", "##000.0"}
Dim providers() As CultureInfo = {New CultureInfo("en-us"), _
New CultureInfo("fr-fr"), _
New CultureInfo("de-de"), _
New CultureInfo("es-es")}
' Display header.
outputBlock.Text += String.Format("{0,24}{1,14}{2,14}{3,14}", providers(0), providers(1), _
providers(2), providers(3)) & vbCrLf
outputBlock.Text &= vbCrLf
' Display a value using each format string.
For Each format As String In formats
' Display the value for each provider on the same line.
outputBlock.Text += String.Format("{0,-12}", format)
For Each provider As CultureInfo In providers
outputBlock.Text += String.Format("{0,12} ", _
value.ToString(format, provider))
Next
outputBlock.Text &= vbCrLf
