Property Value

Type: System::String
The string that separates groups of digits to the left of the decimal in percent values. The default for InvariantInfo is ",".


The property is being set to nullptr.


The property is being set and the NumberFormatInfo is read-only.

The following example demonstrates the effect of changing the PercentGroupSeparator property.

using namespace System;
using namespace System::Globalization;
int main()

   // Gets a NumberFormatInfo associated with the en-US culture.
   CultureInfo^ MyCI = gcnew CultureInfo( "en-US",false );
   NumberFormatInfo^ nfi = MyCI->NumberFormat;

   // Displays a value with the default separator (S", ").
   Double myInt = 1234.5678;
   Console::WriteLine( myInt.ToString( "P", nfi ) );

   // Displays the same value with a blank as the separator.
   nfi->PercentGroupSeparator = " ";
   Console::WriteLine( myInt.ToString( "P", nfi ) );

This code produces the following output.
123, 456.78 %
123 456.78 %
