第1个示范方法

主导提醒:第叁个示范方法:1 SqlConnection conn = new SqlConnection

率先个示范方法:

1 SqlConnection conn = new SqlConnection();

2 conn.ConnectionString = Server=127.0.0.1;User

ID=sa;Password=fdahgdrethj31313210212121;

Database=northwind;Persist Security Info=True;

3 conn.Open();

4 SqlDataAdapter da = new SqlDataAdapter(select * from 表, conn);

5 SqlCommandBuilder thisBulder = new SqlCommandBuilder(da);

6 DataSet ds = new DataSet();

7 da.Fill(ds);

8 ds.WriteXml(@C:/temp.xml);

其次个示范方法:

1 private void WriteXmlToFile(DataSet thisDataSet) 2 { 3 if (thisDataSet
== null) { return; } 4 // Create a file name to write to. 5 string
filename = myXmlDoc.xml; 6 // Create the FileStream to write with. 7
System.IO.FileStream myFileStream = new System.IO.FileStream 8
(filename, System.IO.FileMode.Create); 9 // Create an XmlTextWriter with
the fileStream. 10 System.Xml.XmlTextWriter myXmlWriter = 11 new
System.Xml.XmlTextWriter (myFileStream, System.Text.Encoding.Unicode);
12 // Write to the file with the WriteXml method. 13
thisDataSet.WriteXml(myXmlWriter); 14 myXmlWriter.Close(); 15 }
