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. 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.
CodeExpressionCollection collection = new CodeExpressionCollection();
// Adds a CodeExpression to the collection.
collection.Add(new CodePrimitiveExpression(
System.Convert.ToString(true)));
// Adds an array of CodeExpression objects to the collection.
CodeExpression expressions[] = { new CodePrimitiveExpression(
System.Convert.ToString(true)), new CodePrimitiveExpression(
System.Convert.ToString(true)) };
collection.AddRange(expressions);
// Adds a collection of CodeExpression objects to the collection.
CodeExpressionCollection expressionsCollection = new
CodeExpressionCollection();
expressionsCollection.Add(new CodePrimitiveExpression(
System.Convert.ToString(true)));
expressionsCollection.Add(new CodePrimitiveExpression(
System.Convert.ToString(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(System.
Convert.ToString(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.get_Count();
// Inserts a CodeExpression at index 0 of the collection.
collection.Insert(0, new CodePrimitiveExpression(System.Convert.
ToString(true)));
// Removes the specified CodeExpression from the collection.
CodeExpression expression = new CodePrimitiveExpression(System.Convert.
ToString(true));
collection.Remove(expression);
// Removes the CodeExpression at index 0.
collection.RemoveAt(0);
