CodeExpressionCollection Class
Represents a collection of CodeExpression objects.
Assembly: System (in System.dll)
Provides a simple collection object that can represent a set of Code Document Object Model (CodeDOM) expression objects.
The CodeExpressionCollection class provides a simple collection object that can be used to store a set of CodeExpression objects.
The following example demonstrates the use of the CodeExpressionCollection class methods. 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. 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)
