判斷字典是否包含特定值。

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

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

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

參數

item

KeyValuePair<TKey,TValue>

要在字典中尋找的物件。

傳回

Boolean

如果在字典中找到 item 則為 true，否則為 false。
