如何将DataGridView的数据保存为XML文件 急~~~

Question

高手们指点下谢谢....

Answer 1

用DataSet转XML，DataSet由DataGridView的Datasource得到。
        //将DataSet转换为xml文件
        public static void ConvertDataSetToXMLFile(DataSet xmlDS,string xmlFile)
        {
            MemoryStream stream = null;
            XmlTextWriter writer = null;            try
            {
                stream = new MemoryStream();
                //从stream装载到XmlTextReader
                writer = new XmlTextWriter(stream, Encoding.Unicode);                //用WriteXml方法写入文件.
                xmlDS.WriteXml(writer);
                int count = (int)stream.Length;
                byte[] arr = new byte[count];
                stream.Seek(0, SeekOrigin.Begin);
                stream.Read(arr, 0, count);                //返回Unicode编码的文本
                UnicodeEncoding utf = new UnicodeEncoding();
                StreamWriter sw = new StreamWriter(xmlFile);
                sw.WriteLine("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
                sw.WriteLine(utf.GetString(arr).Trim());
                sw.Close();
            }
            catch( System.Exception ex )
            {
                throw ex;
            }
            finally
            {
                if (writer != null) writer.Close();
            }
        }
