Remarks
This instance 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 and whose GetFormat method returns a NumberFormatInfo object that provides formatting information.
If provider is null 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 displays the string representation of an Int32 value using CultureInfo objects that represent several different cultures.
Dim value As Integer = -16325
' Display value using the invariant culture.
outputBlock.Text &= value.ToString(CultureInfo.InvariantCulture) & vbCrLf
' Display value using the en-GB culture.
outputBlock.Text &= value.ToString(New CultureInfo("en-GB")) & vbCrLf
' Display value using the de-DE culture.
outputBlock.Text &= value.ToString(New CultureInfo("de-DE")) & vbCrLf
' This example displays the following output:
' -16325
' -16325
' -16325
int value = -16325;
// Display value using the invariant culture.
outputBlock.Text += value.ToString(CultureInfo.InvariantCulture) + "\n";
// Display value using the en-GB culture.
outputBlock.Text += value.ToString(new CultureInfo("en-GB")) + "\n";
// Display value using the de-DE culture.
outputBlock.Text += value.ToString(new CultureInfo("de-DE")) + "\n";
// This example displays the following output:
// -16325
// -16325
// -16325
