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）

public void Run(string reportPath, string printerName, DataTable dt1, string dt1SourceName, DataTable dt2, string dt2SourceName,bool isHindeLogo)
{
LocalReport report = new LocalReport();
report.ReportPath = reportPath;//加上报表的路径
report.DataSources.Add(new ReportDataSource(dt1SourceName, dt1));
report.DataSources.Add(new ReportDataSource(dt2SourceName, dt2));
report.EnableExternalImages = true;
ReportParameter rp = new ReportParameter("isHindeLogoImg", isHindeLogo.ToString());//这里我在报表里弄的参数
report.SetParameters(rp);
Export(report);
m_currentPageIndex = ;
Print(printerName);
} private void Export(LocalReport report)

Warning[] warnings;
m_streams = new List<Stream>();
try
{
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
}
catch (Exception ex)
{
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。
while (innerEx != null)
{
//MessageBox.Show(innerEx.Message);
string errmessage = innerEx.Message;
innerEx = innerEx.InnerException;
}
}
foreach (Stream stream in m_streams)
{
stream.Position = ;
}
} private Stream CreateStream(string name, string fileNameExtension, Encoding encoding, string mimeType, bool willSeek)
{
//name 需要进一步处理
Stream stream = new FileStream(name + DateTime.Now.Millisecond + "." + fileNameExtension, FileMode.Create);//为文件名加上时间
m_streams.Add(stream);
return stream;
} private void Print(string printerName)
{
//string printerName = this.TextBox1.Text.Trim();// "傳送至 OneNote 2007";
if (m_streams == null || m_streams.Count == )
return;
PrintDocument printDoc = new PrintDocument();
// string aa = printDoc.PrinterSettings.PrinterName;
if (printerName.Length > )
{
printDoc.PrinterSettings.PrinterName = printerName;
}
foreach (PaperSize ps in printDoc.PrinterSettings.PaperSizes)
{
if (ps.PaperName == "A4")
{
printDoc.PrinterSettings.DefaultPageSettings.PaperSize = ps;
printDoc.DefaultPageSettings.PaperSize = ps;
// printDoc.PrinterSettings.IsDefaultPrinter;//知道是否是预设定的打印机
}
}
if (!printDoc.PrinterSettings.IsValid)
{
string msg = String.Format("Can't find printer " + printerName);
System.Diagnostics.Debug.WriteLine(msg);
return;
}
printDoc.PrintPage += new PrintPageEventHandler(PrintPage);
printDoc.Print();
} private void PrintPage(object sender, PrintPageEventArgs ev)
{
Metafile pageImage = new Metafile(m_streams[m_currentPageIndex]);
ev.Graphics.DrawImage(pageImage, , , , );//設置打印尺寸 单位是像素
m_currentPageIndex++;
ev.HasMorePages = (m_currentPageIndex < m_streams.Count);
}
}
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
