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）

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);

56 Warning[] warnings;

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 }

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
