以静默方式打印报表服务器端
我正在尝试编写一个程序，允许我从服务器端代码打印ssrs报告（.rdl文件）到预定的打印机，而没有任何弹出窗口询问我想要使用哪台打印机可以这样做吗？
编辑
还粘贴了我正在使用的ReportViewerDisposer实现的代码。
与我在这里找到的类ReportViewerDisposer一起使用以下代码，它是更大项目的一部分，但您应该能够轻松地进行调整：
private string m_printerName; private string m_server; private string m_path; private string m_name; private Dictionary m_parameters; private SizeF m_pageSize; private float m_marginLeft; private float m_marginTop;

首先，您需要将SSRS报告呈现为PDF格式，然后您可以直接打印PDF文件而无需打开任何弹出窗口，请参阅下面的代码：
public void PrintPreviewSSRSReport(string reportName) { try { string reportPath = string.Empty; string historyID = null; string deviceInfo = null; string extension = null; string encoding = null; string mimeType = null; string[] streamIDs = null; string format = "PDF"; Byte[] result; ReportExecution2005.Warning[] warnings = null; ExecutionInfo execInfo = new ExecutionInfo(); TrustedUserHeader trusteduserHeader = new TrustedUserHeader(); ExecutionHeader execHeader = new ExecutionHeader(); ServerInfoHeader serviceInfo = new ServerInfoHeader(); MHTools.ReportExecution2005.ReportParameter[] _parameters = null; ParameterValue[] _ParameterValue = null; //Set the report path reportPath = "/Reports/SalesReport"; //Create the object of report execution web service ReportExecutionServiceSoapClient rsExec = new ReportExecutionServiceSoapClient(); //Use this if you don't need to pass the credentials from code rsExec.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation; //Load the reports rsExec.LoadReport(trusteduserHeader, reportPath, historyID, out serviceInfo, out execInfo); execHeader.ExecutionID = execInfo.ExecutionID; //Get the parameters details from load report and eet the value in paremeters if any _parameters = execInfo.Parameters; _ParameterValue = new ParameterValue[1]; _ParameterValue[0] = new ParameterValue(); _ParameterValue[0].Name = _parameters[0].Name; _ParameterValue[0].Value = "12345"; //Set the parameters rsExec.SetExecutionParameters(execHeader, null, _ParameterValue, "en-us", out execInfo); //Render the report rsExec.Render(execHeader, null, format, deviceInfo, out result, out extension, out mimeType, out encoding, out warnings, out streamIDs); //pass the file path where pdf file will be saved using (FileStream stream = File.OpenWrite(PDFFile)) { stream.Write(result, 0, result.Length); } //send the padf file path to printer SendFileToPrinter(PDFFile); } catch (Exception ex) { // } } #region Print SSRS Report [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] private class DOCINFOA { [MarshalAs(UnmanagedType.LPStr)] public string pDocName; [MarshalAs(UnmanagedType.LPStr)] public string pOutputFile; [MarshalAs(UnmanagedType.LPStr)] public string pDataType; } [DllImport("winspool.Drv", EntryPoint = "OpenPrinterA", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] private static extern bool OpenPrinter([MarshalAs(UnmanagedType.LPStr)] string szPrinter, out IntPtr hPrinter, IntPtr pd); [DllImport("winspool.Drv", EntryPoint = "ClosePrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] private static extern bool ClosePrinter(IntPtr hPrinter); [DllImport("winspool.Drv", EntryPoint = "StartDocPrinterA", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] private static extern bool StartDocPrinter(IntPtr hPrinter, Int32 level, [In, MarshalAs(UnmanagedType.LPStruct)] DOCINFOA di); [DllImport("winspool.Drv", EntryPoint = "EndDocPrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] private static extern bool EndDocPrinter(IntPtr hPrinter); [DllImport("winspool.Drv", EntryPoint = "StartPagePrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] private static extern bool StartPagePrinter(IntPtr hPrinter); [DllImport("winspool.Drv", EntryPoint = "EndPagePrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] private static extern bool EndPagePrinter(IntPtr hPrinter); [DllImport("winspool.Drv", EntryPoint = "WritePrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] private static extern bool WritePrinter(IntPtr hPrinter, IntPtr pBytes, Int32 dwCount, out Int32 dwWritten); [DllImport("winspool.drv", CharSet = CharSet.Auto, SetLastError = true)] public static extern bool GetDefaultPrinter(StringBuilder pszBuffer, ref int size); /// /// This function gets the pdf file name. /// This function opens the pdf file, gets all its bytes & send them to print. /// /// Printer Name /// Pdf File Name /// true on success, false on failure public bool SendFileToPrinter(string pdfFileName) { try { #region Get Connected Printer Name PrintDocument pd = new PrintDocument(); StringBuilder dp = new StringBuilder(256); int size = dp.Capacity; if (GetDefaultPrinter(dp, ref size)) { pd.PrinterSettings.PrinterName = dp.ToString().Trim(); } #endregion Get Connected Printer Name // Open the PDF file.

- 首先在开发项目中为指向报表服务器的Reporting Services Web服务添加Web引用。 这可以通过在Visual Studio中右键单击项目并选择“添加Web引用…”来完成。 您应该在“ http：//localhost/reportserver/reportservice.asmx ”中添加对本地报表服务器（localhost）的引用。
- 使用ReportingService类使用某些步骤进行打印。
按照这个 。
