Thiết chiếu tại NET cho các API SQL Trước khi bạn có thể sử dụng các API trong ứng dụng NET. Của bạn., Bạn cần tạo một tham chiếu đến thư viện đặc biệt bạn sẽ sử dụng. Các thư viện bạn sẽ được sử dụng là thư viện COM | Setting References in .NET for the SQL APIs Before you can use the APIs within your .NET application you need to create a reference to the particular library you are going to use. The libraries you will be using are COM libraries therefore you will not have certain benefits of using the .NET Framework such as some of the performance gains. However you can still use the libraries. Hopefully if and when the libraries are updated to the framework you will be able to convert your code over to use them. To access the necessary libraries choose Add Reference from the Project menu. Click on the COM tab to display possible COM libraries. Next click Select after highlighting the following libraries Microsoft DTSPackage Object Library and Microsoft SQLDMO Object Library. Click OK to close the dialog box. At that point if you open the Object Browser you can expand the Interop.SQLDMO library and even highlight the SQL Server object to see the properties and methods available. This is shown in Figure 7.4. Figure 7.4. The objects displayed here are now available for use in your applications. As you work through the following How-Tos the various collections objects properties and methods that you will be using will be listed as you need them. So many objects are available that it would take multiple pages to display the whole trees of the SQL-DMO and SQL-DTS object .
