我已經(jīng)在 Windows 10 上設(shè)置了我的 iis 服務(wù)器，并且我已經(jīng)在其上部署了一個 mvc-5 網(wǎng)絡(luò)應(yīng)用程序，除了 Crystal Reports PrintToPrinter 之外，一切都運(yùn)行良好，當(dāng)我嘗試調(diào)用此方法時，沒有任何打印，網(wǎng)絡(luò)應(yīng)用程序什么也不做，只是掛起那里。但是當(dāng)我在同一臺機(jī)器上用 vs17 開發(fā)這個應(yīng)用程序時，printToPrinter 方法工作正常。它只會在 iis 上發(fā)布后卡住。我努力了popt.PrinterName = printerSettings.PrinterName; rd.ReportClientDocument.PrintOutputController.PrintReport(popt);這個方法也是。這是我的實際代碼：        DataTable dt = new DataTable();        string constr = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;        using (SqlConnection con = new SqlConnection(constr))        {            using (SqlCommand cmd = new SqlCommand(sqlQuery))            {                using (SqlDataAdapter sda = new SqlDataAdapter())                {                    cmd.Connection = con;                    sda.SelectCommand = cmd;                    sda.Fill(dt);                }            }        }        ReportDocument rd = new ReportDocument();        rd.Load(Path.Combine(Server.MapPath("~/Reporting/Crystals/rptKitchenCopy.rpt")));        rd.SetDataSource(dt);        Response.Buffer = false;        Response.ClearContent();        Response.ClearHeaders();        Stream stream = rd.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);        stream.Seek(0, SeekOrigin.Begin);        PrinterSettings settings = new PrinterSettings();        System.Drawing.Printing.PrintDocument pDoc = new System.Drawing.Printing.PrintDocument();        CrystalDecisions.Shared.PrintLayoutSettings PrintLayout = new CrystalDecisions.Shared.PrintLayoutSettings();        System.Drawing.Printing.PrinterSettings printerSettings = new System.Drawing.Printing.PrinterSettings();        var dpn = settings.PrinterName;        printerSettings.PrinterName = dpn;        System.Drawing.Printing.PageSettings pSettings = new System.Drawing.Printing.PageSettings(printerSettings);我希望它也可以使用我在同一臺機(jī)器上托管的默認(rèn)打印機(jī)在 iis 服務(wù)器中打印。C＃asp.net-mvciis印刷水晶報表
