定義

命名空間:

System.Net.Http

組件:

System.Net.Http.dll

判斷 ICollection<T> 是否包含特定值。

 virtual bool System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<System.String,System.Object>>.Contains(System::Collections::Generic::KeyValuePair<System::String ^, System::Object ^> item) = System::Collections::Generic::ICollection<System::Collections::Generic::KeyValuePair<System::String ^, System::Object ^>>::Contains;

bool ICollection<KeyValuePair<string,object>>.Contains (System.Collections.Generic.KeyValuePair<string,object> item);

abstract member System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<System.String,System.Object>>.Contains : System.Collections.Generic.KeyValuePair<string, obj> -> bool
override this.System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<System.String,System.Object>>.Contains : System.Collections.Generic.KeyValuePair<string, obj> -> bool

Function Contains (item As KeyValuePair(Of String, Object)) As Boolean Implements ICollection(Of KeyValuePair(Of String, Object)).Contains

參數

item

KeyValuePair<String,Object>

要在 ICollection<T> 中尋找的物件。

傳回

Boolean

如果在 true 中找到 item，則為 ICollection<T>，否則為 false。

實作

Contains(T)

備註

這個成員是明確介面成員實作， 只有在 HttpRequestOptions 執行個體轉換成 ICollection<T> 介面時，才能使用這個成員。
