示例
下面的示例演示如何使用 CodeAttributeDeclarationCollection 类方法。
// Creates an empty CodeAttributeDeclarationCollection.
CodeAttributeDeclarationCollection collection = new CodeAttributeDeclarationCollection();
// Adds a CodeAttributeDeclaration to the collection.
collection.Add( new CodeAttributeDeclaration("DescriptionAttribute", new CodeAttributeArgument(new CodePrimitiveExpression("Test Description"))) );
// Adds an array of CodeAttributeDeclaration objects
// to the collection.
CodeAttributeDeclaration[] declarations = { new CodeAttributeDeclaration(), new CodeAttributeDeclaration() };
collection.AddRange( declarations );
// Adds a collection of CodeAttributeDeclaration objects
// to the collection.
CodeAttributeDeclarationCollection declarationsCollection = new CodeAttributeDeclarationCollection();
declarationsCollection.Add( new CodeAttributeDeclaration("DescriptionAttribute", new CodeAttributeArgument(new CodePrimitiveExpression("Test Description"))) );
declarationsCollection.Add( new CodeAttributeDeclaration("BrowsableAttribute", new CodeAttributeArgument(new CodePrimitiveExpression(true))) );
collection.AddRange( declarationsCollection );
// Tests for the presence of a CodeAttributeDeclaration in
// the collection, and retrieves its index if it is found.
CodeAttributeDeclaration testdeclaration = new CodeAttributeDeclaration("DescriptionAttribute", new CodeAttributeArgument(new CodePrimitiveExpression("Test Description")) );
int itemIndex = -1;
if( collection.Contains( testdeclaration ) )
itemIndex = collection.IndexOf( testdeclaration );
// Copies the contents of the collection, beginning at index 0,
// to the specified CodeAttributeDeclaration array.
// 'declarations' is a CodeAttributeDeclaration array.
collection.CopyTo( declarations, 0 );
// Retrieves the count of the items in the collection.
int collectionCount = collection.Count;
// Inserts a CodeAttributeDeclaration at index 0 of the collection.
collection.Insert( 0, new CodeAttributeDeclaration("DescriptionAttribute", new CodeAttributeArgument(new CodePrimitiveExpression("Test Description"))) );
// Removes the specified CodeAttributeDeclaration from
// the collection.
CodeAttributeDeclaration declaration = new CodeAttributeDeclaration("DescriptionAttribute", new CodeAttributeArgument(new CodePrimitiveExpression("Test Description")) );
collection.Remove( declaration );
// Removes the CodeAttributeDeclaration at index 0.
collection.RemoveAt(0);
' Creates an empty CodeAttributeDeclarationCollection.
Dim collection As New CodeAttributeDeclarationCollection()
' Adds a CodeAttributeDeclaration to the collection.
collection.Add(New CodeAttributeDeclaration("DescriptionAttribute", New CodeAttributeArgument(New CodePrimitiveExpression("Test Description"))))
' Adds an array of CodeAttributeDeclaration objects to the collection.
Dim declarations As CodeAttributeDeclaration() = {New CodeAttributeDeclaration(), New CodeAttributeDeclaration()}
collection.AddRange(declarations)
' Adds a collection of CodeAttributeDeclaration objects to
' the collection.
Dim declarationsCollection As New CodeAttributeDeclarationCollection()
declarationsCollection.Add(New CodeAttributeDeclaration("DescriptionAttribute", New CodeAttributeArgument(New CodePrimitiveExpression("Test Description"))))
declarationsCollection.Add(New CodeAttributeDeclaration("BrowsableAttribute", New CodeAttributeArgument(New CodePrimitiveExpression(True))))
collection.AddRange(declarationsCollection)
' Tests for the presence of a CodeAttributeDeclaration in the
' collection, and retrieves its index if it is found.
Dim testdeclaration As New CodeAttributeDeclaration("DescriptionAttribute", New CodeAttributeArgument(New CodePrimitiveExpression("Test Description")))
Dim itemIndex As Integer = -1
If collection.Contains(testdeclaration) Then
itemIndex = collection.IndexOf(testdeclaration)
End If
' Copies the contents of the collection beginning at index 0 to the specified CodeAttributeDeclaration array.
' 'declarations' is a CodeAttributeDeclaration array.
collection.CopyTo(declarations, 0)
' Retrieves the count of the items in the collection.
Dim collectionCount As Integer = collection.Count
' Inserts a CodeAttributeDeclaration at index 0 of the collection.
collection.Insert(0, New CodeAttributeDeclaration("DescriptionAttribute", New CodeAttributeArgument(New CodePrimitiveExpression("Test Description"))))
' Removes the specified CodeAttributeDeclaration from the collection.
Dim declaration As New CodeAttributeDeclaration("DescriptionAttribute", New CodeAttributeArgument(New CodePrimitiveExpression("Test Description")))
collection.Remove(declaration)
' Removes the CodeAttributeDeclaration at index 0.
collection.RemoveAt(0)
