A string array that contains the names of the custom attributes supported by the switch, or null if there no custom attributes are supported.
Examples
The following code sample shows an override of the GetSupportedAttributes method for a custom switch.
public class MySourceSwitch : SourceSwitch
{
int sourceAttribute = 0;
public MySourceSwitch(string n) : base(n) { }
public int CustomSourceSwitchAttribute
{
get
{
foreach (DictionaryEntry de in this.Attributes)
if (de.Key.ToString().ToLower() == "customsourceswitchattribute")
sourceAttribute = (int)de.Value;
return sourceAttribute;
}
set { sourceAttribute = (int)value; }
}
protected override string[] GetSupportedAttributes()
{
return new string[] { "customsourceSwitchattribute" };
}
}
Public Class MySourceSwitch
Inherits SourceSwitch
Private sourceAttribute As Integer = 0
Public Sub New(ByVal n As String)
MyBase.New(n)
End Sub
Public Property CustomSourceSwitchAttribute() As Integer
Get
Dim de As DictionaryEntry
For Each de In Me.Attributes
If de.Key.ToString().ToLower() = "customsourceswitchattribute" Then
sourceAttribute = Fix(de.Value)
End If
Next de
Return sourceAttribute
End Get
Set(ByVal value As Integer)
sourceAttribute = Fix(Value)
End Set
End Property
Protected Overrides Function GetSupportedAttributes() As String()
Return New String() {"customsourceSwitchattribute"}
End Function 'GetSupportedAttributes
End Class
Remarks
The default implementation for the GetSupportedAttributes method returns null. If a switch is added in a configuration file and custom attributes are specified that are not included in the string array returned by GetSupportedAttributes, a ConfigurationException is thrown when the switch is loaded.
Notes to Inheritors
When inheriting from the Switch class or a derived class, you can override the GetSupportedAttributes() method to provide custom attributes for your class.
