NumberFormatInfo.CurrencyGroupSizes Property

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets or sets the number of digits in each group to the left of the decimal in currency values.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Property CurrencyGroupSizes As Integer()
public int[] CurrencyGroupSizes { get; set; }

Property Value

Type: array<System.Int32[]
The number of digits in each group to the left of the decimal in currency values. The default for InvariantInfo is a one-dimensional array with only one element, which is set to 3.

Exceptions

Exception Condition
ArgumentNullException

The property is being set to nulla null reference (Nothing in Visual Basic).

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 object is read-only.

Remarks

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 CurrencyDecimalSeparator string. 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, 4, 5 }, the digits are grouped similar to "$55,55555,55555,55555,4444,333.00". If the array contains { 3, 4, 0 }, the digits are grouped similar to "$55555555555555555,4444,333.00".

Class Example


   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)

      ' Gets a NumberFormatInfo associated with the en-US culture.
      Dim nfi As NumberFormatInfo = New CultureInfo("en-US").NumberFormat

      ' Displays a value with the default separator (".").
      Dim myInt As Int64 = 123456789012345
      outputBlock.Text += String.Format(myInt.ToString("C", nfi)) & vbCrLf

      ' Displays the same value with different groupings.
      Dim mySizes1 As Integer() = {2, 3, 4}
      Dim mySizes2 As Integer() = {2, 3, 0}
      nfi.CurrencyGroupSizes = mySizes1

      nfi.CurrencyGroupSizes = mySizes2
      outputBlock.Text += String.Format(myInt.ToString("C", nfi)) & vbCrLf
