C#实现打印（反射）

C#实现打印（反射）

前端：

function printTask(obj) { var rowData = $("#tb").DataTable().row($(obj).parents('tr')[0]).data(); var url = "/Material/PrintContract"; var inputs = ''; $('

后台：

public FileResult PrintContract(string conid){ MemoryStream ms = new FileHelper().PrintContractNew(mesContract, detailsEntity, pnEntity.FirstOrDefault(), cuInfo, filiale, cuInuser, sysUser, dtReturn); return File(ms, "application/pdf");}

public MemoryStream PrintContractNew(MesContract mesContract, IList mesContractDetails, MesPn pnEntity, CuInfo cuInfo, DataFiliale filiale, IList cuInusers, SysUser sysUser, DataTable dtReturn) { string filePath = ""; //根据合同类型需要走两个分支，采购根据供应商调用不同的模板 string contractType = mesContract.MesType; if (contractType == "采购") { string supplierName = mesContract.MesCuid; if (supplierName == "SUP501") //商飞公司 filePath = HttpContext.Current.Server.MapPath("~/Files/Modal/ShanFeiProcurementContract.docx"); else //采购的其他公司 filePath = HttpContext.Current.Server.MapPath("~/Files/Modal/ProcurementContract.docx"); } else //送修和索赔合同 filePath = HttpContext.Current.Server.MapPath("~/Files/Modal/SendRepair.docx"); //判断文件是否存在 if (!File.Exists(filePath)) return null; Document document = new Document(filePath); if (contractType == "采购") { if (mesContractDetails != null || mesContractDetails.Count > 0) { // TODO 代码瞎写，采购中每项都来自，自己的选项中， foreach (var item in mesContractDetails) item.MesCurrency = mesContract.MesCurrency; PrintPurchse(document, mesContractDetails); //TODO 给税率赋值，瞎写，这个税率等于总税率 mesContract.WengvJdjpjxrq = mesContractDetails[0].WengvZtpbBlfr; } } else PrintUnPurchse(document, mesContractDetails, dtReturn); string emergencyLevel = GetSortedDictionaryValue(mesContract.MesEmer, GetEmergencyLevelType());//获取紧急程度 mesContract.WengvJslz = emergencyLevel; string tranSportType = GetSortedDictionaryValue(mesContract.MesTransport, GetTranSportType());//运输方式 mesContract.WengvYxhvbzzdg = tranSportType; string payName = GetByEnglisConverToChine(dtPay, mesContract.MesPaymentmet, "BM_CODE", "BM_ABBR");//付款方式 mesContract.WengvUgfunxeyrh = payName; string currencyName = GetByEnglisConverToChine(dtCurrency, mesContract.MesCurrency, "RMB_CODE", "RMB_CNAME"); //币种 mesContract.WengvHayznxnk = currencyName; string moneyCapital = ConvertToChinese(mesContract.MesSum.ToString());//小写转大写 mesContract.MesMoneyCapital = moneyCapital; ReKey(document.Range, mesContract); //合同信息 ReKey(document.Range, cuInfo);//客户公司信息 ReKey(document.Range, filiale);//打印甲方公司 CuInuser cuInuser = cuInusers.FirstOrDefault(); if (cuInuser == null) cuInuser = new CuInuser(); ReKey(document.Range, cuInuser);//客户公司的人员信息 if (sysUser == null) sysUser = new SysUser(); ReKey(document.Range, sysUser);//用户信息 return GetMeoryStreamByFileStream(filePath, document); }

private static void ReKey(Range range, object model) { if (model == null) return; Type t = model.GetType(); PropertyInfo[] pi = t.GetProperties(); foreach (PropertyInfo p in pi) { var v = p.GetValue(model, null); string va = ""; if (v != null) { if (v.GetType() == typeof(DateTime) || v.GetType() == typeof(Nullable)) { va = DateTime.Parse(v.ToString()).ToString("yyyy-MM-dd"); } else { va = v.ToString(); } } FindReplaceOptions op = new FindReplaceOptions(); op.FindWholeWordsOnly = false; range.Replace("$" + p.Name + "$", va, op); //range.Replace("$" + p.Name + "$", va); } }

private static MemoryStream GetMeoryStreamByFileStream(string filePath, Document doc) { if (!File.Exists(filePath)) return null; using (FileStream stream = File.OpenRead(filePath)) { if (stream == null) return null; MemoryStream ms = new MemoryStream(); doc.Save(ms, SaveFormat.Pdf); ms.Flush(); ms.Seek(0, SeekOrigin.Begin); return ms; } }

生成table：

private Table PrintMesContractDetail(Document document, IList mesContractDetails) { try { Table tb = (Table)document.GetChild(NodeType.Table, 1, true); int i = 1; foreach (var item in mesContractDetails) { //序号、件号、名称、数量、单位、 状态、不含税单价、含税单价、含税总价、币种、交货期、证书、备注 string[] colunValues = new string[] { //TODO 其他列用不用判断 i.ToString(),//序号 item.MesPno, //件号 item.MesProductname,//名称 item.MesCount, //数量 GetByEnglisConverToChine(dtUnit,item.MesUnit,"BM_CODE","BM_CNAME"),//单位 "NE",//状态 item.MesNottxaprice.ToString(),//不含税单价 item.MesTxaprice.ToString(),//含税单价 item.MesTxaprice.ToString(),//含税单价 GetByEnglisConverToChine(dtCurrency,item.MesCurrency,"RMB_CODE","RMB_CNAME"),//币种 item.MesDeliverydate.ToString(),//交货期 item.MesCertification= item.MesCertification==null?"":item.MesCertification//证书 }; i++; var tr = CreateRow(12, colunValues, document); tb.Rows.Add(tr); } return tb; } catch (Exception ex) { LogWriter.Write(LOG_CATEGORY.WIN_UI, LOG_LEVEL.ERROR, "PrintMesContractDetail:" + ex.ToString()); return null; } }

生成table：

private static Row CreateRow(int columnCount, string[] columnValues, Document doc) { Row r2 = new Row(doc); for (int i = 0; i < columnCount; i++) { if (columnValues.Length > i) { var cell = CreateCell(columnValues[i], doc); r2.Cells.Add(cell); } else { var cell = CreateCell("", doc); r2.Cells.Add(cell); } } return r2; }

把不需要的代码去掉就行.
