定義

命名空間:

System.Collections.Concurrent

組件:

System.Collections.Concurrent.dll

來源:

取得值，這個值指出 ICollection<T> 是否包含具有指定之索引鍵的項目。

 virtual bool System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<TKey,TValue>>.Contains(System::Collections::Generic::KeyValuePair<TKey, TValue> keyValuePair) = System::Collections::Generic::ICollection<System::Collections::Generic::KeyValuePair<TKey, TValue>>::Contains;

bool ICollection<KeyValuePair<TKey,TValue>>.Contains (System.Collections.Generic.KeyValuePair<TKey,TValue> keyValuePair);

abstract member System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<TKey,TValue>>.Contains : System.Collections.Generic.KeyValuePair<'Key, 'Value> -> bool
override this.System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<TKey,TValue>>.Contains : System.Collections.Generic.KeyValuePair<'Key, 'Value> -> bool

Function Contains (keyValuePair As KeyValuePair(Of TKey, TValue)) As Boolean Implements ICollection(Of KeyValuePair(Of TKey, TValue)).Contains

參數

keyValuePair

KeyValuePair<TKey,TValue>

要在 ICollection<T> 中尋找的索引鍵。

傳回

Boolean

如果 true 包含具有指定索引鍵的項目，則為 ICollection<T>，否則為 false。
