示例

下面的示例演示如何使用CodeExpressionCollection类方法。The following example demonstrates the use of the CodeExpressionCollection class methods. 该示例创建类的新实例, 并使用方法将语句添加到集合, 返回其索引, 并在特定索引点添加或移除特性。The example creates a new instance of the class and uses the methods to add statements to the collection, return their index, and add or remove attributes at a specific index point.

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

// Adds a CodeExpression to the collection.
collection->Add( gcnew CodePrimitiveExpression( true ) );

// Adds an array of CodeExpression objects to the collection.
array<CodeExpression^>^expressions = {gcnew CodePrimitiveExpression( true ),gcnew CodePrimitiveExpression( true )};
collection->AddRange( expressions );

// Adds a collection of CodeExpression objects to the collection.
CodeExpressionCollection^ expressionsCollection = gcnew CodeExpressionCollection;
expressionsCollection->Add( gcnew CodePrimitiveExpression( true ) );
expressionsCollection->Add( gcnew CodePrimitiveExpression( true ) );
collection->AddRange( expressionsCollection );

// Tests for the presence of a CodeExpression in the 
// collection, and retrieves its index if it is found.
CodeExpression^ testComment = gcnew CodePrimitiveExpression( true );
int itemIndex = -1;
if ( collection->Contains( testComment ) )
   itemIndex = collection->IndexOf( testComment );

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

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

// Inserts a CodeExpression at index 0 of the collection.
collection->Insert( 0, gcnew CodePrimitiveExpression( true ) );

// Removes the specified CodeExpression from the collection.
CodeExpression^ expression = gcnew CodePrimitiveExpression( true );
collection->Remove( expression );

// Removes the CodeExpression at index 0.
collection->RemoveAt( 0 );
// Creates an empty CodeExpressionCollection.
CodeExpressionCollection collection = new CodeExpressionCollection();
