The following code example removes all the CustomError objects from the CustomErrorCollection collection. Refer to the code example in the CustomErrorCollection class topic to learn how to get the collection.
// Using the Clear method.
if (!customErrorsSection.SectionInformation.IsLocked)
{
// Execute the Clear method.
customErrorsCollection.Clear();
configuration.Save();
}
' Using the Clear method.
If Not customErrorsSection.SectionInformation.IsLocked Then
' Execute the Clear method.
customErrorsCollection.Clear()
configuration.Save()
End If
The result of updating the configuration file after calling the Clear method is dependent upon the ConfigurationSaveMode chosen. To update the configuration file, you use one of these two overloads: Save and Save.
If you use the Save.method, the following conditions apply.
If you pass a Full or Modified parameter value, then a
clear
element is inserted into theclientTarget
section of the configuration file at the current hierarchy level.If you pass the Minimal parameter value, a series of
remove
elements are added to the clientTarget Element (ASP.NET Settings Schema) of the configuration file at the current hierarchy level. Each removes all references to anadd
element defined in a parent configuration file at a higher level in the hierarchy. When you use Minimal, there is one additional property on the collection that affects what gets serialized to the configuration file: EmitClear, which isfalse
by default. The following conditions apply.If the EmitClear set to
true
,clear
element is inserted into theclientTarget
section of the configuration file at the current hierarchy level. This removes all references to theadd
elements defined in the parent configuration files at higher levels in the hierarchy.If the EmitClear flag is set to
false
, theclear
element is removed from theclientTarget
section of the configuration file at the current hierarchy level, if it exists.
The Clear method actually deletes the add
elements defined in the clientTarget
section of the configuration file at the current hierarchy level. It also removes all references to the add elements defined in the parent configuration files at higher levels in the hierarchy.
Note
The add
elements are not deleted from the clientTarget
section of the parent configuration files.
