CultureInfo.CompareInfo Property

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

Gets the CompareInfo object that defines how to compare strings for the culture.

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

Syntax

'Declaration
Public Overridable ReadOnly Property CompareInfo As CompareInfo

public virtual CompareInfo CompareInfo { get; }

Property Value

Type: System.Globalization.CompareInfo
The object that defines how to compare strings for the culture.

Remarks

The user might choose to override some of the values associated with the current system culture. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. The CultureInfo object that represents the current culture reflects these customizations.

Examples

The following example creates es-ES and es-ES_tradnl CultureInfo objects, uses the CompareInfo property to retrieve their CompareInfo objects, and tests the CompareInfo objects for equality. It indicates that the two CompareInfo objects are not equal.

Imports System.Globalization

   Public Sub Demo(outputBlock As System.Windows.Controls.TextBlock)
      outputBlock.FontFamily = New FontFamily("Courier New")
      ' Instantiate es-ES culture with international and traditional sort orders.

      Dim esTrad As New CultureInfo("es-ES_tradnl")

      ' Retrieve respective CompareInfo objects.
      Dim compEsIntl As CompareInfo = esIntl.CompareInfo
      Dim compEsTrad As CompareInfo = esTrad.CompareInfo

      ' Display information on CultureInfo objects.
