获取一个值，该值指示 ICollection<T> 是否包含具有指定键的元素。

 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

参数

keyValuePair
KeyValuePair<TKey,TValue>

要在 ICollection<T> 中定位的键。

返回

Boolean

如果 true 包含具有指定键的元素，则为 ICollection<T>；否则为 false。

实现
