A Boolean that indicates whether the collection can be accessed by name, description, ID, or index.

namespace ExtendedProperties_Testing
{
class Program

// The package is one of the SSIS samples.
string mySample = @"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";
// Create the application, and load the sample.
Application app = new Application();
Package pkg = app.LoadPackage(mySample, null);
// Get the extended properties collection from the package.
ExtendedProperties myExtProps = pkg.ExtendedProperties;
// Use the ID.
Boolean hasGUID = myExtProps.Contains("{F3B7314E-DB1E-4CCA-A856-2E617A1B3265}");
Console.WriteLine("The extended property contains that GUID? {0}", hasGUID);
Console.WriteLine();
