定義

命名空間:
System.Activities.Presentation.Model
組件:
System.Activities.Presentation.dll

判斷字典是否包含指定的索引鍵/值組。

 virtual bool System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<System.Activities.Presentation.Model.ModelItem,System.Activities.Presentation.Model.ModelItem>>.Contains(System::Collections::Generic::KeyValuePair<System::Activities::Presentation::Model::ModelItem ^, System::Activities::Presentation::Model::ModelItem ^> item) = System::Collections::Generic::ICollection<System::Collections::Generic::KeyValuePair<System::Activities::Presentation::Model::ModelItem ^, System::Activities::Presentation::Model::ModelItem ^>>::Contains;
bool ICollection<KeyValuePair<ModelItem,ModelItem>>.Contains (System.Collections.Generic.KeyValuePair<System.Activities.Presentation.Model.ModelItem,System.Activities.Presentation.Model.ModelItem> item);
abstract member System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<System.Activities.Presentation.Model.ModelItem,System.Activities.Presentation.Model.ModelItem>>.Contains : System.Collections.Generic.KeyValuePair<System.Activities.Presentation.Model.ModelItem, System.Activities.Presentation.Model.ModelItem> -> bool
override this.System.Collections.Generic.ICollection<System.Collections.Generic.KeyValuePair<System.Activities.Presentation.Model.ModelItem,System.Activities.Presentation.Model.ModelItem>>.Contains : System.Collections.Generic.KeyValuePair<System.Activities.Presentation.Model.ModelItem, System.Activities.Presentation.Model.ModelItem> -> bool
Function Contains (item As KeyValuePair(Of ModelItem, ModelItem)) As Boolean Implements ICollection(Of KeyValuePair(Of ModelItem, ModelItem)).Contains

參數

item
KeyValuePair<ModelItem,ModelItem>

要尋找的索引鍵/值組。

傳回

Boolean

如果字典包含指定的索引鍵/值組，則為 true；否則為 false。

實作

Contains(T)
