xml文件实现一次性导入功能(泉州需求)

1.Import.ashx.cs文件代码内容：

 public void ProcessRequest(HttpContext context)
        {
			context.Response.Clear();
			string username = context.Request.QueryString["username"];//操作人
            HttpFileCollection postedFile = context.Request.Files;
            //判断是否有数据
            if (postedFile != null && postedFile.Count > 0)
            {
                int length = postedFile[0].ContentLength;//文件大小
                string filename = System.IO.Path.GetFileNameWithoutExtension(postedFile[0].FileName);//文件名，不包括扩展名
				string path = HttpContext.Current.Server.MapPath("/XmlFiles/");//文件存放路径
				if (!System.IO.Directory.Exists(path))
					System.IO.Directory.CreateDirectory(path);//创建文件夹
				string allfile = path + filename + DateTime.Now.ToString("yyyy-MM-dd") + ".xml";//文件路径+文件名 
				postedFile[0].SaveAs(allfile);//保存文件内容 

				if (length > 0 && length < 512000)//文件最大允许500k
                {
                    string type = System.IO.Path.GetExtension(postedFile[0].FileName);//文件类型
					
					if (type == ".xml")
					{
						//读取文件
						QzSpecialisticDAL dal = new QzSpecialisticDAL();
						QZ_IMPORT_LOG log = new QZ_IMPORT_LOG();
						try
						{
							XmlDocument xmlDoc = new XmlDocument();
							//加载xml 
							xmlDoc.Load(allfile); //path+filename为文件路径

							//读取指定的节点
							#region 1.配送台账：读取QZ_DISPATCH_DETAILS节点

							QZ_DISPATCH_DETAILS details = dal.GetModels<QZ_DISPATCH_DETAILS>(xmlDoc,"/QZ_SPECIALISTIC/QZ_DISPATCH_DETAILS");
							dal.InsertXmlData(details.DetailList,username,out log);

							log.IMPORT_NAME = "配送台账";//导入界面
							if (!dal.AddImportLog(log))
							{
								string res1 = "{"status" : "success","msg": "配送台账日志插入错误上传失败！"}";
								context.Response.Write(res1);
								return;
							}
							#endregion

							#region 2.零售台账：读取QZ_SPECIALISTIC_SALEDETAILS节点

							QZ_SPECIALISTIC_SALEDETAILS sales = dal.GetModels<QZ_SPECIALISTIC_SALEDETAILS>(xmlDoc,"/QZ_SPECIALISTIC/QZ_SPECIALISTIC_SALEDETAILS");
							dal.InsertXmlData(sales.DetailList,out log);

							log.IMPORT_NAME = "零售台账";//导入界面 
							if (!dal.AddImportLog(log))
							{
								string res1 = "{"status" : "success","msg": "零售台账日志插入错误上传失败！"}";
								context.Response.Write(res1);
								return;
							}
							#endregion

							string res = "{"status" : "success","msg": "上传成功！"}";
							context.Response.Write(res);
						}
						catch (Exception e)
						{
							string res = "{"status" : "error","msg": "文件格式错误上传失败！"}";
							context.Response.Write(res);
							return;
						} 
					}
					else
					{
						string res = "{"status" : "error","msg": "只允许上传.xml类型的文件！"}";
						context.Response.Write(res);
						return;
					}
                }
                else
                {
                    string res = "{"status" : "error","msg": "文件过大！"}";
                    context.Response.Write(res);
                    return;
                }
            }
        }

InsertXmlData方法，实现入库校验操作：

public void InsertXmlData<T>(List<T> models,string username,out QZ_IMPORT_LOG logmodel) where T : new()
		{
			QZ_IMPORT_LOG log =new QZ_IMPORT_LOG();
			int sum = models.Count;
			int j = 0;
			string mismessage = "";
			string[] s = models.ToString().Split(new char[] { '.' },StringSplitOptions.RemoveEmptyEntries);
			string model = s[s.Length - 1].Replace("]","").Trim();

			if (models != null)//判断节点下是否有子节点 
			{
				//循环遍历detail结点下的子结点    
				foreach (T submodel in models)
				{
					//校验Id是否重复  
					string id = submodel.GetType().GetProperty("ID").GetValue(submodel,null).ToString();
					if (ExixtsID(model,id))
					{
						if (OracleHelper.Insert<T>(submodel))//插入数据库
						{
							j++;//成功上传条数 
						}
						else
						{
							//上传失败
							mismessage += "id=" + id + "数据插入错误，上传失败；";
						}
					}
					else
					{
						//上传失败
						mismessage += "id=" + id + "已导入；";
					}
				} 
				//录入上传日志数据
				log.IMPORT_DATE = DateTime.Now;//导入时间 
				log.IMPORT_TABLENAME = model;//导入表名
				log.IMPORT_NUM = sum;//导入总条数
				log.IMPORT_NUM_OK = j;//导入成功条数
				log.REMARK = mismessage;//未成功错误信息  
				log.OPERATOR = username;//操作人
			}
			logmodel = log;
		}

public T GetModels<T>(XmlDocument xmlDoc,string singleNode) where T : new()
		{
			XmlNode xmlNode = xmlDoc.SelectSingleNode(singleNode);
			StringReader stream = new StringReader(xmlNode.OuterXml);
			string xml = stream.ReadToEnd();
			return XmlDeserialize<T>(xml,Encoding.UTF8); 
		}

public T XmlDeserialize<T>(string s,Encoding encoding) where T : new()
		{
			if (string.IsNullOrEmpty(s))
				throw new ArgumentNullException("s");
			if (encoding == null)
				throw new ArgumentNullException("encoding");

			XmlSerializer mySerializer = new XmlSerializer(typeof(T));
			using (MemoryStream ms = new MemoryStream(encoding.GetBytes(s)))
			{
				using (StreamReader sr = new StreamReader(ms,encoding))
				{
					return (T)mySerializer.Deserialize(sr);
				}
			}
		}
