最近在做一个打印清单的，但是rdlc报表自带的工具栏中的打印按钮只有在ie内核下的浏览器才可以使用（其他的就会 隐藏），这导致了使用火狐和谷歌浏览器还有使用linux系统的客户打印成了问题，于是就自己百度搜，谷歌搜，然后就解决了，下面放上源码
打印类 PrintHelp（我需要两个table座位数据源所以参数中有两个datatable）
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Web; 5 using System.IO; 6 using Microsoft.Reporting.WebForms; 7 using System.Drawing.Printing; 8 using System.Drawing.Imaging; 9 using System.Text; 10 using System.Data; 11 12 /// <summary> 13 /// PrintHelp 的摘要描述 14 /// </summary> 15 public class PrintHelp 16 { 17 18 19 private int m_currentPageIndex; 20 private IList<Stream> m_streams; 21 /// <summary> 22 /// 23 /// </summary> 24 /// <param name="reportPath">報表路徑</param> 25 /// <param name="printerName">打印機名稱（使用默認打印機，不賦值）</param> 26 /// <param name="dt1">報表數據源1</param> 27 /// <param name="dt1SourceName">報表中數據源1對應名稱</param> 28 /// <param name="dt2">報表數據源2</param> 29 /// <param name="dt2SourceName">報表中數據源2對應名稱</param> 30 public void Run(string reportPath, string printerName, DataTable dt1, string dt1SourceName, DataTable dt2, string dt2SourceName,bool isHindeLogo) 31 { 32 LocalReport report = new LocalReport(); 33 report.ReportPath = reportPath;//加上报表的路径 34 report.DataSources.Add(new ReportDataSource(dt1SourceName, dt1)); 35 report.DataSources.Add(new ReportDataSource(dt2SourceName, dt2)); 36 report.EnableExternalImages = true; 37 ReportParameter rp = new ReportParameter("isHindeLogoImg", isHindeLogo.ToString());//这里我在报表里弄的参数 38 report.SetParameters(rp); 39 Export(report); 40 m_currentPageIndex = 0; 41 Print(printerName); 42 } 43 44 private void Export(LocalReport report) 45 { 46 string deviceInfo = 47 "<DeviceInfo>" + 48 " <OutputFormat>EMF</OutputFormat>" + 49 " <PageWidth>210mm</PageWidth>" + 50 " <PageHeight>297mm</PageHeight>" + 51 " <MarginTop>5mm</MarginTop>" + 52 " <MarginLeft>10mm</MarginLeft>" + 53 " <MarginRight>10mm</MarginRight>" + 54 " <MarginBottom>5mm</MarginBottom>" + 55 "</DeviceInfo>";//这里是设置打印的格式 边距什么的
56 Warning[] warnings; 57 m_streams = new List<Stream>(); 58 try 59 { 60 report.Render("Image", deviceInfo, CreateStream, out warnings);//一般情况这里会出错的 使用catch得到错误原因 一般都是简单错误 61 } 62 catch (Exception ex) 63 { 64 Exception innerEx = ex.InnerException;//取内异常。因为内异常的信息才有用，才能排除问题。 65 while (innerEx != null) 66 { 67 //MessageBox.Show(innerEx.Message); 68 string errmessage = innerEx.Message; 69 innerEx = innerEx.InnerException; 70 } 71 } 72 foreach (Stream stream in m_streams) 73 { 74 stream.Position = 0; 75 } 76 } 77 78 private Stream CreateStream(string name, string fileNameExtension, Encoding encoding, string mimeType, bool willSeek) 79 { 80 //name 需要进一步处理 81 Stream stream = new FileStream(name + DateTime.Now.Millisecond + "." + fileNameExtension, FileMode.Create);//为文件名加上时间 82 m_streams.Add(stream); 83 return stream; 84 } 85 86 private void Print(string printerName) 87 { 88 //string printerName = this.TextBox1.Text.Trim();// "傳送至 OneNote 2007"; 89 if (m_streams == null || m_streams.Count == 0) 90 return; 91 PrintDocument printDoc = new PrintDocument(); 92 // string aa = printDoc.PrinterSettings.PrinterName; 93 if (printerName.Length > 0) 94 { 95 printDoc.PrinterSettings.PrinterName = printerName; 96 } 97 foreach (PaperSize ps in printDoc.PrinterSettings.PaperSizes) 98 { 99 if (ps.PaperName == "A4") 100 { 101 printDoc.PrinterSettings.DefaultPageSettings.PaperSize = ps; 102 printDoc.DefaultPageSettings.PaperSize = ps; 103 // printDoc.PrinterSettings.IsDefaultPrinter;//知道是否是预设定的打印机 104 } 105 } 106 if (!printDoc.PrinterSettings.IsValid) 107 { 108 string msg = String.Format("Can't find printer " + printerName); 109 System.Diagnostics.Debug.WriteLine(msg); 110 return; 111 } 112 printDoc.PrintPage += new PrintPageEventHandler(PrintPage); 113 printDoc.Print(); 114 } 115 116 117 private void PrintPage(object sender, PrintPageEventArgs ev) 118 { 119 Metafile pageImage = new Metafile(m_streams[m_currentPageIndex]); 120 ev.Graphics.DrawImage(pageImage, 0, 0, 827, 1169);//設置打印尺寸 单位是像素 121 m_currentPageIndex++; 122 ev.HasMorePages = (m_currentPageIndex < m_streams.Count); 123 } 124 }
调用很简单 直接一句话
new PrintHelp().Run(AppDomain.CurrentDomain.BaseDirectory + "\Reports\Report.rdlc", this.TextBox1.Text.Trim(), stationapplication.dthead, "headsource", stationapplication.dtmessage, "datasource", true);
由于原来的工具栏没了打印按钮 所以也就没有存在的必要了 隐藏掉 自己做一个工具栏出来
缩放、上一页下一页首页什么的
/// <summary> /// 刷新 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button7_Click(object sender, EventArgs e) { this.ReportViewer1.LocalReport.Refresh(); } /// <summary> /// 首页 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button8_Click(object sender, EventArgs e) { this.ReportViewer1.CurrentPage = 1; } /// <summary> /// 上一页 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button9_Click(object sender, EventArgs e) { if (this.ReportViewer1.CurrentPage != 1) { this.ReportViewer1.CurrentPage--; } } /// <summary> /// 下一页 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button10_Click(object sender, EventArgs e) { if (this.ReportViewer1.CurrentPage != this.ReportViewer1.LocalReport.GetTotalPages()) { this.ReportViewer1.CurrentPage++; } } /// <summary> /// 尾页 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Button11_Click(object sender, EventArgs e) { this.ReportViewer1.CurrentPage = this.ReportViewer1.LocalReport.GetTotalPages(); } /// <summary> /// 缩放 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { this.ReportViewer1.ZoomMode = ZoomMode.Percent; this.ReportViewer1.ZoomPercent = Convert.ToInt32(this.DropDownList1.SelectedValue); }
导出文件
protected void Button3_Click(object sender, EventArgs e) { ExportFile(FileType.PDF, "out.pdf"); } protected void Button4_Click(object sender, EventArgs e) { ExportFile(FileType.Image, "out.jpeg");//这里可以使用任意的图片格式 只要修改out.jpeg为其他格式的名字就可以了 } protected void Button5_Click(object sender, EventArgs e) { ExportFile(FileType.Excel, "out.xls"); } protected void Button6_Click(object sender, EventArgs e) { ExportFile(FileType.Word, "out.doc"); } #region 導出文件 private void ExportFile(FileType ft, string filename) { CreateFile(ft, filename); string strPath = Server.MapPath(filename); DownloadFile(strPath, filename); } private void CreateFile(FileType ft, string filename) { Warning[] warnings; string[] streamids; string mimeType; string encoding = "utf-8"; string extension; byte[] bytes = this.ReportViewer1.LocalReport.Render(ft.ToString(), null, out mimeType, out encoding, out extension, out streamids, out warnings); FileStream fs = new FileStream(HttpContext.Current.Server.MapPath(filename), FileMode.Create); fs.Write(bytes, 0, bytes.Length); fs.Close(); fs.Dispose(); } public void DownloadFile(string path, string name) { try { System.IO.FileInfo file = new System.IO.FileInfo(path); Response.Clear(); Response.Charset = "utf-8"; Response.ContentEncoding = System.Text.Encoding.UTF8; // 添加头信息，为"文件下载/另存为"对话框指定默认文件名 Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(name)); // 添加头信息，指定文件大小，让浏览器能够显示下载进度 Response.AddHeader("Content-Length", file.Length.ToString()); // 指定返回的是一个不能被客户端读取的流，必须被下载 Response.ContentType = "application/octet-stream"; // 把文件流发送到客户端 Response.WriteFile(file.FullName); // 停止页面的执行 HttpContext.Current.ApplicationInstance.CompleteRequest(); } catch (Exception ex) { Response.Write("<script>alert('系统出现以下错误://n" + ex.Message + "!//n请尽快与管理员联系.')</script>"); } }
发送email 传真fax 什么的就不说了 很简单 搜一下一箩筐
