Dataset is ADO. net. dataset can be regarded as a database in memory, and dataset is a set of independent data from the database. the so-called independence means that dataset is still available even if the data link is disconnected or the database is closed. dataset uses XM

The process of self-study by DataReader or dataset?_

Ado. NET provides two primary classes for reading data. Through this article we can learn how to choose between the two. I often hear people ask this question: "Should I use a DataReader class or a DataSet class in a ASP.net Web application?" "I often see this misconception in many articles and newsgroup postings that DataReader (SqlDataReader or OleDbDataReader abbreviations) are better than datasets. Sometimes I also see the opposite story. In fact

Use of the DataSet class in C #

The DataSet class is one of the most core members of ADO, and is the most frequently exposed class for developing database applications based on the. NET Platform programming language. Each dataset has a lot of datatables and relationships. Relationship should also be a kind of table, especially, this table is only used to contact two data tables. Each DataTable has many DataRows and Datacols, and also incl

The difference between a DataReader and a DataSet

Excerpt from: http://www.cnblogs.com/zhjjNo1/archive/2009/08/26/1554420.htmlThe first kind of explanationThe biggest difference between the DataReader and the DataSet is that when DataReader is used, it always occupies SqlConnection (commonly known as: non-disconnected), and when you operate the database online, Any operation on SqlConnection throws an DataReader exception. Because DataReader only loads one piece of data in memory at a time, the memor

On the DataSet object in ASP.

When we operate on the database, we always take the data out of the database, then put it in a "container", and then the data from the "container" is displayed in the foreground, and the role of this container is a dataset is the most common and important, It can be said that datasets play a role in the database and the foreground.Let's talk about the use of datasets.
