c# 解压文件的 解压之后没有存进数据库 没有看的解压之后 文件

   Stream stream = HttpContext.Current.Request.InputStream;
            account = HttpContext.Current.Request.Params["Account"];
            if (account == null || account == "")
            {
                account = "unknown";
            }
            desZipFilePrefix = ServiceHelp.getDesZipFileName(account);
            fileSuffixNme = ".rar";
            //读取文件流将文件保存到服务器的特定目录下
            compressFilePath = OperateZipFile.writeCompressFile(stream, desZipFilePrefix + fileSuffixNme);
            if (Directory.Exists(System.Web.HttpContext.Current.Server.MapPath("DesFile")) == false)
            {
                Directory.CreateDirectory(System.Web.HttpContext.Current.Server.MapPath("DesFile"));
            }
            deCompressFilePath = Path.Combine(System.Web.HttpContext.Current.Server.MapPath("DesFile"), desZipFilePrefix);
            OperateZipFile.UnRar(deCompressFilePath, compressFilePath, desZipFilePrefix + fileSuffixNme);

            //解析shapefile文件
            FeatureShapeFileParse featureShapeFileParse = new FeatureShapeFileParse();
            featureShapeFileParse.filePathForShp = featureShapeFileParse.getShpPath(deCompressFilePath);
            featureShapeFileParse.filePathForShx = featureShapeFileParse.getShxPath(deCompressFilePath);
            featureShapeFileParse.filePathForDbf = featureShapeFileParse.getDbfPath(deCompressFilePath);
            List<ShpFileData> shpFileDataList = featureShapeFileParse.readShpFile();
           List<DbfFileData> dbfFileDataList = featureShapeFileParse.readDbfile();

           if (dbfFileDataList == null)
           {
               new Normal_AdminlogsDAL().SaveMapServiceLog(" 解压失败，或者文件为空");
               return;
           }

            SurveyFeatureAddRequest surveyFeatureAddRequest = getSurveyFeatureAddRequest(shpFileDataList, dbfFileDataList);

           string featureSql = string.Format(" INSERT INTO [PRO_PollingCheckLog]([P_ProID],[P_UserID],[P_CheckLogName],[P_StartTime],[P_EndTime],[P_Attributes],[P_LayerName],[P_FeatureName],[P_PicURI],[P_MediaURI],[P_Note],[P_StatusID],[P_CreateUserName],[P_CreateTime]) VALUES ('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}','{8}','{9}','{10}','{11}','{12}',getdate() ) ;",

            if (exerst > 0)
            {
                //删除解压后的临时文件
                deleteTempFile();

            }
            else {
                new Normal_AdminlogsDAL().SaveMapServiceLog("插入失败");//Test

 dbfFileDataList 总是等 null

解决方案

你的压缩文件是什么类型，单独执行解压缩是否正确，或者报什么错误。

解决方案二：

c# 压缩解压文件

解决方案三：

OperateZipFile.UnRar 调用失败了
估计你传入的参数格式可能不正确等，所以失败了

解决方案四：

应该是参数不正确。。。。。。。
