示例

下面的示例演示如何使用 CodeStatementCollection 类。The following example demonstrates how to use the CodeStatementCollection class. 该示例创建类的新实例, 并使用多个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删除语句。The example creates a new instance of the class and uses several methods to add statements to the collection, return their index, and add or remove statements at a specific index point.

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

// Adds a CodeStatement to the collection.
collection->Add( gcnew CodeCommentStatement( "Test comment statement" ) );

// Adds an array of CodeStatement objects to the collection.
array<CodeStatement^>^statements = {gcnew CodeCommentStatement( "Test comment statement" ),gcnew CodeCommentStatement( "Test comment statement" )};
collection->AddRange( statements );

// Adds a collection of CodeStatement objects to the collection.
CodeStatement^ testStatement = gcnew CodeCommentStatement( "Test comment statement" );
CodeStatementCollection^ statementsCollection = gcnew CodeStatementCollection;
statementsCollection->Add( gcnew CodeCommentStatement( "Test comment statement" ) );
statementsCollection->Add( gcnew CodeCommentStatement( "Test comment statement" ) );
statementsCollection->Add( testStatement );
collection->AddRange( statementsCollection );

// Tests for the presence of a CodeStatement in the 
// collection, and retrieves its index if it is found.
int itemIndex = -1;
if ( collection->Contains( testStatement ) )
   itemIndex = collection->IndexOf( testStatement );

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

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

// Inserts a CodeStatement at index 0 of the collection.
collection->Insert( 0, gcnew CodeCommentStatement( "Test comment statement" ) );

// Removes the specified CodeStatement from the collection.
collection->Remove( testStatement );

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

// Adds a CodeStatement to the collection.
collection.Add( new CodeCommentStatement("Test comment statement") );

// Adds an array of CodeStatement objects to the collection.
CodeStatement[] statements = { 
                new CodeCommentStatement("Test comment statement"), 
                new CodeCommentStatement("Test comment statement")};
collection.AddRange( statements );

// Adds a collection of CodeStatement objects to the collection.
CodeStatement testStatement = new CodeCommentStatement("Test comment statement");
CodeStatementCollection statementsCollection = new CodeStatementCollection();
statementsCollection.Add( new CodeCommentStatement("Test comment statement") );
statementsCollection.Add( new CodeCommentStatement("Test comment statement") );
statementsCollection.Add( testStatement );

collection.AddRange( statementsCollection );

// Tests for the presence of a CodeStatement in the 
// collection, and retrieves its index if it is found.
int itemIndex = -1;
if( collection.Contains( testStatement ) )
    itemIndex = collection.IndexOf( testStatement );


// Copies the contents of the collection beginning at index 0 to the specified CodeStatement array.
// 'statements' is a CodeStatement array.
CodeStatement[] statementArray = new CodeStatement[collection.Count];
collection.CopyTo( statementArray, 0 );

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

// Inserts a CodeStatement at index 0 of the collection.
collection.Insert( 0, new CodeCommentStatement("Test comment statement") );

// Removes the specified CodeStatement from the collection.
collection.Remove( testStatement );

// Removes the CodeStatement at index 0.
collection.RemoveAt(0);
' Creates an empty CodeStatementCollection.
Dim collection As New CodeStatementCollection

' Adds a CodeStatement to the collection.
collection.Add(New CodeCommentStatement("Test comment statement"))

' Adds an array of CodeStatement objects to the collection.
Dim statements As CodeStatement() = {New CodeCommentStatement("Test comment statement"), New CodeCommentStatement("Test comment statement")}
collection.AddRange(statements)

' Adds a collection of CodeStatement objects to the collection.
Dim testStatement As New CodeStatement
Dim statementsCollection As New CodeStatementCollection
statementsCollection.Add(New CodeCommentStatement("Test comment statement"))
statementsCollection.Add(New CodeCommentStatement("Test comment statement"))

collection.AddRange(statementsCollection)

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

' Copies the contents of the collection beginning at index 0 to the specified CodeStatement array.
' 'statements' is a CodeStatement array.
Dim statementArray(collection.Count - 1) As CodeStatement
collection.CopyTo(statementArray, 0)

' Retrieves the count of the items in the collection.
Dim collectionCount As Integer = collection.Count

' Inserts a CodeStatement at index 0 of the collection.
collection.Insert(0, New CodeCommentStatement("Test comment statement"))

' Removes the specified CodeStatement from the collection.
collection.Remove(testStatement)

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