Xml文件操作和文件操作(FileInfo类)

Xml文件操作和文件操作(FileInfo类)

  1. 上传文件

　2。写Xml文件

   3.  文件拷贝

            for (int i = 0; i < ListCount; i++)

            {

               //二级子目录image

                writer.WriteStartElement("image");

               //属性

                writer.WriteAttributeString("id", (i + 1).ToString());

                writer.WriteAttributeString("Thumb", listCase[i].CASE_B2.Substring(listCase[i].CASE_B2.LastIndexOf('/') + 1));

               //三级节点copy

                writer.WriteStartElement("copy");

               //节点的文本内容

               //writer.WriteString("文本内容");

               //写<[CDATA[..]]>
