This article mainly introduces "ADO.NET technology example analysis". In daily operation, I believe many people have doubts about ADO.NET technology example analysis problems. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "ADO.NET technology example analysis". Next, please follow the editor to study!

The relationship between the two can be described in this way. The .NET Framework is the running supporting environment of ADO.NET technology, and its internal class collection includes all the class collections of ADO.NET. There are relatively many types of databases that can be operated, as long as they provide Ole Db and ODBC providers locally, respectively.

Although there may seem to be some connection between ADO.NET and ADO in terms of name, ADO.NET technology is actually a completely new technology. As for Microsoft's naming it ADO.NET, it is largely based on commercial operation considerations, because ADO technology is so popular that naming it ADO.NET will undoubtedly attract program developers who have used ADO technology. ADO.NET technology does not completely abandon the technology of ADO, so it will be easier for program developers who have studied ADO to master ADO.NET.

The so-called ADO.NET technology is a technology that enables programmers to develop database applications quickly and efficiently using Visual Studio 2005. Isn't it? In the previous chapter, we have unwittingly developed a database application using ADO.NET technology.

In fact, an ADO.NET is a collection of specific classes in the class library of the .NET Framework that can manipulate the data in the database, as shown in the figure code.

Public void CheckLog (string Log)

{

If (File.Exists (LogFile))

{

WriteLog (Log)

}

Else

{

CreateLog ()

WriteLog (Log)

}

}

Private void CreateLog ()

{

StreamWriter SW

SW = File.CreateText (LogFile)

SW.WriteLine ("Log created at:" +

DateTime.Now.ToString ("dd-MM-yyyy hh:mm:ss"))

SW.Close ()

}

Private void WriteLog (string Log)

{

Using (StreamWriter SW = File.AppendText (LogFile))

{

SW.WriteLine (Log)

SW.Close ()

}

}

At this point, the study of "ADO.NET Technology example Analysis" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
