示例

The following code example loads an existing package that has two connections. It iterates through the connection managers in the package and prints out the values for various properties, including the HostType. The CreationName is one way to differentiate the underlying connection type that is being hosted.

    class Program

            string mySample = @"C:\Program Files\Microsoft SQL Server\90\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx";
            
            // Create an application and load the sample.
            Application app = new Application();
            Package pkg = app.LoadPackage(mySample, null);
            Connections myConns = pkg.Connections;
            int connCount = myConns.Count;

            // the values for various properties.
