Examples

The following example demonstrates how to use the CodeParameterDeclarationExpressionCollection 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 CodeParameterDeclarationExpressionCollection.
CodeParameterDeclarationExpressionCollection collection = new CodeParameterDeclarationExpressionCollection();

// Adds a CodeParameterDeclarationExpression to the collection.
collection.Add( new CodeParameterDeclarationExpression(typeof(int), "testIntArgument") );

// Adds an array of CodeParameterDeclarationExpression objects
// to the collection.
CodeParameterDeclarationExpression[] parameters = { new CodeParameterDeclarationExpression(typeof(int), "testIntArgument"), new CodeParameterDeclarationExpression(typeof(bool), "testBoolArgument") };
collection.AddRange( parameters );

// Adds a collection of CodeParameterDeclarationExpression objects
// to the collection.
CodeParameterDeclarationExpressionCollection parametersCollection = new CodeParameterDeclarationExpressionCollection();
parametersCollection.Add( new CodeParameterDeclarationExpression(typeof(int), "testIntArgument") );
parametersCollection.Add( new CodeParameterDeclarationExpression(typeof(bool), "testBoolArgument") );
collection.AddRange( parametersCollection );

// Tests for the presence of a CodeParameterDeclarationExpression
// in the collection, and retrieves its index if it is found.
CodeParameterDeclarationExpression testParameter = new CodeParameterDeclarationExpression(typeof(int), "testIntArgument");
int itemIndex = -1;
if( collection.Contains( testParameter ) )
    itemIndex = collection.IndexOf( testParameter );

// Copies the contents of the collection beginning at index 0 to the specified CodeParameterDeclarationExpression array.
// 'parameters' is a CodeParameterDeclarationExpression array.
collection.CopyTo( parameters, 0 );

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

// Inserts a CodeParameterDeclarationExpression at index 0
// of the collection.
collection.Insert( 0, new CodeParameterDeclarationExpression(typeof(int), "testIntArgument") );

// Removes the specified CodeParameterDeclarationExpression
// from the collection.
CodeParameterDeclarationExpression parameter = new CodeParameterDeclarationExpression(typeof(int), "testIntArgument");
collection.Remove( parameter );

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

' Adds a CodeParameterDeclarationExpression to the collection.
collection.Add(New CodeParameterDeclarationExpression(GetType(Integer), "testIntArgument"))

' Adds an array of CodeParameterDeclarationExpression objects 
' to the collection.
Dim parameters As CodeParameterDeclarationExpression() = {New CodeParameterDeclarationExpression(GetType(Integer), "testIntArgument"), New CodeParameterDeclarationExpression(GetType(Boolean), "testBoolArgument")}
collection.AddRange(parameters)

' Adds a collection of CodeParameterDeclarationExpression 
' objects to the collection.
Dim parametersCollection As New CodeParameterDeclarationExpressionCollection()
parametersCollection.Add(New CodeParameterDeclarationExpression(GetType(Integer), "testIntArgument"))
parametersCollection.Add(New CodeParameterDeclarationExpression(GetType(Boolean), "testBoolArgument"))
collection.AddRange(parametersCollection)

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

' Copies the contents of the collection beginning at index 0 to the specified CodeParameterDeclarationExpression array.
' 'parameters' is a CodeParameterDeclarationExpression array.
collection.CopyTo(parameters, 0)

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

' Inserts a CodeParameterDeclarationExpression at index 0 
' of the collection.
collection.Insert(0, New CodeParameterDeclarationExpression(GetType(Integer), "testIntArgument"))

' Removes the specified CodeParameterDeclarationExpression 
' from the collection.
Dim parameter As New CodeParameterDeclarationExpression(GetType(Integer), "testIntArgument")
collection.Remove(parameter)

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

Remarks

The CodeParameterDeclarationExpressionCollection class provides a simple collection object that can be used to store a set of CodeParameterDeclarationExpression objects.

Constructors
