FrozenDictionary<TKey,TValue>.ICollection<KeyValuePair<TKey,TValue>>.Contains 方法

定义

命名空间:

System.Collections.Frozen

程序集:

System.Collections.Immutable.dll

Source:

FrozenDictionary.cs

确定 ICollection<T> 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

参数

item

KeyValuePair<TKey,TValue>

要在 ICollection<T> 中定位的对象。

返回

Boolean

如果在 true 中找到 item，则为 ICollection<T>；否则为 false。

实现

Contains(T)
