Summary

总结

SqlDataReader objects allow you to read data in a fast forward-only manner.  You obtain data by reading each row from the data stream.  Call the Close method of the SqlDataReader to ensure there are not any resource leaks. 

SqlDataReader对象允许你以一种快速的只向前的方式读取数据。你从数据流中读取每一行来读取数据。调用SqlDataReader的Close方法保证资源泄漏不会发生。
