System.Globalization Namespace   NumberFormatInfo Class

---

Sets or retrieves the number of digits in each group to the left of the decimal in numeric values.

[ VB ]
public Property NumberGroupSizes As Integer ( ) 

[ C# ]
public int [ ] NumberGroupSizes {get; set;}

[ C++ ]
public: __property int get_NumberGroupSizes ( );
public: __property void set_NumberGroupSizes ( int __gc [ ] );

[ JScript ]
function get NumberGroupSizes ( ) : int [ ];
public function set NumberGroupSizes ( int [ ] );

The number of digits in each group to the left of the decimal in numeric values. The default for InvariantInfo is a one-dimensional array with only one element, which is set to 3.

Exception Type	Condition
ArgumentException	The property is being set and the array contains an entry that is less than 0 or greater than 9. -or- The property is being set and the array contains an entry, other than the last entry, that is set to 0.
InvalidOperationException	The property is being set and the NumberFormatInfo is read-only.

Every element in the one-dimensional array must be an integer from 1 through 9. The last element can be 0.

The first element of the array defines the number of elements in the least significant group of digits immediately to the left of the NumberDecimalSeparator. Each subsequent element refers to the next significant group of digits to the left of the previous group. If the last element of the array is not 0, the remaining digits are grouped based on the last element of the array. If the last element is 0, the remaining digits are not grouped.

For example, if the array contains { 3, 2 }, the digits will be grouped similar to "1,23,456.00". If the array contains { 3, 2, 0 }, the digits will be grouped similar to "1234,56,789.00".

The below shows the NumberGroupSizes used for each of the available cultures.
