Implements

• ICollection
• ICollection<KeyValuePair<TKey, TValue>>
• IDeserializationCallback
• IDictionary
• IDictionary<TKey, TValue>
• IEnumerable
• IEnumerable<KeyValuePair<TKey, TValue>>
• IReadOnlyCollection<KeyValuePair<TKey, TValue>>
• IReadOnlyDictionary<TKey, TValue>
• ISerializable

Remarks

Using the OpcDictionary<TKey, TValue> requires an OPC UA server which defines the according non-generic type which uses specific type arguments for TKey and TValue. A client application in turn have to manually define the server defined / used combination of the generic OpcDictionary<TKey, TValue> type and its specific type arguments for TKey and TValue.

Constructors

Methods

Name	Description
RegisterTypestatic · 3 overloads	Registers the OpcDictionary<TKey, TValue> using the TKey and TValue to define a non-generic encodable data object type to create in case there a data instance is to be created for the type definition identified by the combination of OpcDictionary<TKey, TValue>, TKey and TValue (on which this method is called) within the namespace index with the number two.

Inherits members from Dictionary<TKey, TValue>.
