MessageFilterTable<TFilterData>.TryGetValue Method

Checks whether a filter is stored in the filter table.

Namespace:  System.ServiceModel.Dispatcher
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public bool TryGetValue(
	MessageFilter filter,
	out TFilterData data
)

Parameters

filter
Type: System.ServiceModel.Dispatcher.MessageFilter
The filter that is used as a key to retrieve the data.
data
Type: TFilterData%
The data associated with the filter.

Return Value

Type: System.Boolean
true if there is a filter in the filter table that has data associated with it; otherwise false.

Implements

IDictionary<TKey, TValue>.TryGetValue(TKey, TValue)

This method is an efficient way to check whether a filter is in the filter table because when the filter is not present, it returns false instead of throwing an exception. If you try to retrieve the filter from the table and it is not there, an exception is thrown.
