[C#] In C#, this property is the indexer for the PropertyDictionary class.
public object this[object key] { get; set; }| Parameter | Type | Description |
|---|---|---|
| key | System.Object | The property key for which to search. |
Property Value
- System.Object:
The value of the property with the specified key.
Keys
Gets the collection of property keys that have been registered in this dictionary.
public ReadOnlyCollection<object> Keys { get; }Property Value
- System.Collections.ObjectModel.ReadOnlyCollection<System.Object>:
The collection of property keys that have been registered in this dictionary.
Methods
Add(Object, Object)
Adds a property to the dictionary.
public void Add(object key, object value)| Parameter | Type | Description |
|---|---|---|
| key | System.Object | A key that identifies the property. |
| value | System.Object | The property value. |
ContainsKey(Object)
Returns whether the dictionary contains a property with the specified key.
public bool ContainsKey(object key)| Parameter | Type | Description |
|---|---|---|
| key | System.Object | The property key for which to search. |
Returns
- System.Boolean:
trueif the dictionary contains a property with the specified key; otherwise,false.
GetOrCreateSingleton<TValue>(PropertyDictionary.Creator<TValue>)
Returns a property value if found; otherwise, uses a specified delegate to create a new instance.
public TValue GetOrCreateSingleton<TValue>(PropertyDictionary.Creator<TValue> creator)- Type Parameters:
-
TValue-The type of property value.
| Parameter | Type | Description |
|---|---|---|
| creator | PropertyDictionary.Creator<TValue> | A delegate that is used to create a new value instance if the property is not yet found. |
Returns
- TValue:
The singleton property value.
Remarks
This overload uses the TValue Type as the property key for which to search.
GetOrCreateSingleton<TValue>(Object, PropertyDictionary.Creator<TValue>)
Returns a property value if found; otherwise, uses a specified delegate to create a new instance.
public TValue GetOrCreateSingleton<TValue>(object key, PropertyDictionary.Creator<TValue> creator)- Type Parameters:
-
TValue-The type of property value.
| Parameter | Type | Description |
|---|---|---|
| key | System.Object | The property key for which to search. |
| creator | PropertyDictionary.Creator<TValue> | A delegate that is used to create a new value instance if the property is not yet found. |
Returns
- TValue:
The singleton property value.
Remove(Object)

-
TValue-The type of property value.
| Parameter | Type | Description |
