示例

下面的代码示例演示如何使用 DesignerVerbCollection 类。该示例创建类的新实例，并使用多种方法将语句添加到集合、返回其索引，以及在特定索引点添加或删除属性。

// Creates an empty DesignerVerbCollection.
DesignerVerbCollection^ collection = gcnew DesignerVerbCollection;

// Adds a DesignerVerb to the collection.
collection->Add( gcnew DesignerVerb( "Example designer verb",gcnew EventHandler( this, &Class1::ExampleEvent ) ) );

// Adds an array of DesignerVerb objects to the collection.
array<DesignerVerb^>^ verbs = {
   gcnew DesignerVerb( "Example designer verb", gcnew EventHandler( this, &Class1::ExampleEvent ) ),
   gcnew DesignerVerb( "Example designer verb", gcnew EventHandler( this, &Class1::ExampleEvent ) )};
collection->AddRange( verbs );

// Adds a collection of DesignerVerb objects to the collection.
DesignerVerbCollection^ verbsCollection = gcnew DesignerVerbCollection;
verbsCollection->Add( gcnew DesignerVerb( "Example designer verb", gcnew EventHandler( this, &Class1::ExampleEvent ) ) );
verbsCollection->Add( gcnew DesignerVerb( "Example designer verb", gcnew EventHandler( this, &Class1::ExampleEvent ) ) );
collection->AddRange( verbsCollection );

// Tests for the presence of a DesignerVerb in the collection,
// and retrieves its index if it is found.
DesignerVerb^ testVerb = gcnew DesignerVerb( "Example designer verb", gcnew EventHandler( this, &Class1::ExampleEvent ) );
int itemIndex = -1;
if ( collection->Contains( testVerb ) )
         itemIndex = collection->IndexOf( testVerb );

// Copies the contents of the collection, beginning at index 0,
// to the specified DesignerVerb array.
// 'verbs' is a DesignerVerb array.
collection->CopyTo( verbs, 0 );

// Retrieves the count of the items in the collection.
int collectionCount = collection->Count;

// Inserts a DesignerVerb at index 0 of the collection.
collection->Insert( 0, gcnew DesignerVerb( "Example designer verb", gcnew EventHandler( this, &Class1::ExampleEvent ) ) );

// Removes the specified DesignerVerb from the collection.
DesignerVerb^ verb = gcnew DesignerVerb( "Example designer verb", gcnew EventHandler( this, &Class1::ExampleEvent ) );
collection->Remove( verb );

// Removes the DesignerVerb at index 0.
collection->RemoveAt( 0 );

// Creates an empty DesignerVerbCollection.
DesignerVerbCollection collection = new DesignerVerbCollection();

// Adds a DesignerVerb to the collection.
collection.Add( new DesignerVerb("Example designer verb", new EventHandler(this.ExampleEvent)) );

// Adds an array of DesignerVerb objects to the collection.
DesignerVerb[] verbs = { new DesignerVerb("Example designer verb", new EventHandler(this.ExampleEvent)), new DesignerVerb("Example designer verb", new EventHandler(this.ExampleEvent)) };

int collectionCount = collection.Count;

// Inserts a DesignerVerb at index 0 of the collection.
collection.Insert( 0, new DesignerVerb("Example designer verb", new EventHandler(this.ExampleEvent)) );

// Removes the specified DesignerVerb from the collection.
DesignerVerb verb = new DesignerVerb("Example designer verb", new EventHandler(this.ExampleEvent));
collection.Remove( verb );

// Removes the DesignerVerb at index 0.
collection.RemoveAt(0);
