RegexStringValidatorAttribute Class

Declaratively instructs the .NET Framework to perform string validation on a configuration property using a regular expression. This class cannot be inherited.

Namespace:  System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)

<AttributeUsageAttribute(AttributeTargets.Property)> _
Public NotInheritable Class RegexStringValidatorAttribute _
	Inherits ConfigurationValidatorAttribute
Dim instance As RegexStringValidatorAttribute

You use the RegexStringValidatorAttribute to decorate a configuration property, which will instruct the .NET Framework to validate the property using the RegexStringValidator and pass to it the value of the decorating parameters.

You may apply RegexStringValidatorAttribute objects to property types only.

The following example shows how to decorate the properties of a custom ConfigurationSection object using the RegexStringValidatorAttribute object.

<ConfigurationProperty("alias2", _
DefaultValue:="alias.txt", _
IsRequired:=True, _
IsKey:=False), _
RegexStringValidator("\w+\S*")> _
Public Property Alias2() As String 
        Return CStr(Me("alias2"))
    End Get 
    Set(ByVal value As String)
        Me("alias2") = value
    End Set 
End Property
