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();

// Adds a CodeExpression to the collection.
collection.Add( new CodePrimitiveExpression(true) );

// Adds an array of CodeExpression objects to the collection.
CodeExpression[] expressions = { new CodePrimitiveExpression(true), new CodePrimitiveExpression(true) };
collection.AddRange( expressions );

// Adds a collection of CodeExpression objects to the collection.
CodeExpressionCollection expressionsCollection = new CodeExpressionCollection();
expressionsCollection.Add( new CodePrimitiveExpression(true) );
expressionsCollection.Add( new 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 = new 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, new CodePrimitiveExpression(true) );

// Removes the specified CodeExpression from the collection.
CodeExpression expression = new CodePrimitiveExpression(true);
collection.Remove( expression );

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

' Creates an empty CodeExpressionCollection.
Dim collection As New CodeExpressionCollection()

' Adds a CodeExpression to the collection.
collection.Add(New CodePrimitiveExpression(True))

' Adds an array of CodeExpression objects to the collection.
Dim expressions As CodeExpression() = {New CodePrimitiveExpression(True), New CodePrimitiveExpression(True)}
collection.AddRange(expressions)

' Adds a collection of CodeExpression objects to the collection.
Dim expressionsCollection As New CodeExpressionCollection()
expressionsCollection.Add(New CodePrimitiveExpression(True))
expressionsCollection.Add(New CodePrimitiveExpression(True))
collection.AddRange(expressionsCollection)

' Tests for the presence of a CodeExpression in the 
' collection, and retrieves its index if it is found.
Dim testComment = New CodePrimitiveExpression(True)
Dim itemIndex As Integer = -1
If collection.Contains(testComment) Then
    itemIndex = collection.IndexOf(testComment)
End If

' 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.
Dim collectionCount As Integer = collection.Count

' Inserts a CodeExpression at index 0 of the collection.
collection.Insert(0, New CodePrimitiveExpression(True))

' Removes the specified CodeExpression from the collection.
Dim expression = New CodePrimitiveExpression(True)
collection.Remove(expression)

' Removes the CodeExpression at index 0.
collection.RemoveAt(0)
