Dictionary<TKey,TValue>.Clear Method

Definition

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Source:

Dictionary.cs

Removes all keys and values from the Dictionary<TKey,TValue>.

public:
 virtual void Clear();

public void Clear ();

abstract member Clear : unit -> unit
override this.Clear : unit -> unit

Public Sub Clear ()

Implements

Clear() Clear()

Remarks

The Count property is set to 0, and references to other objects from elements of the collection are also released. The capacity remains unchanged.

This method is an O(n) operation, where n is the capacity of the dictionary.

.NET Core 3.0+ only: this mutating method may be safely called without invalidating active enumerators on the Dictionary<TKey,TValue> instance. This does not imply thread safety.
