Introducing two simple sample codes for database generation xml

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");

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 }
