Question

我有一个Windows窗体（C＃、. NET 4.6.1），该窗体在没有报表查看器的情况下打印rdlc报表。在Visual Studio中，报表看起来不错；字体和边距与报表设计器中的完全相同。当我发布我的应用程序并在另一台计算机上尝试时，它会更改字体并切断左侧边距。我试图在报表设计器中更改字体和边距，并更改传递给打印机的边距（请参见下面的代码），但是在已发布的计算机上，它始终以其他字体和左侧的字体进行打印。我该如何解决？

在这一点上，我的猜测是（1.）发布时需要包括其他文件。我已经包括了rdlc，所以我不确定还包括什么。也许一些参考DLL报告？（2.）我需要将字体名称传递给PrintRDLCReport类中的某些东西。同样，不确定这是什么样子。（3.）我需要另一种类型的“构建操作”而不是“内容”。我不知道还能选择什么。

任何想法都将不胜感激。在机器上运行后，我昨天发表了这篇文章。我只需要在客户端计算机上运行它即可。

这是已打印报告的扫描图像。当我通过Visual Studio运行应用程序时，最上面的一行来自报告（这是我希望它看起来的样子）。底线是我发布并安装该应用程序后从另一台计算机上获得的。

以下是直接打印我的报告的代码：

            LocalReport report = new LocalReport();
            report.ReportPath = @".\Reports\TrayLabels.rdlc";
            report.DataSources.Add(
                new Microsoft.Reporting.WinForms.ReportDataSource("ReportDataSource",
                    filtersToBuild));
            PrintRDLCReport.PrintToPrinter(report);

这是PrintRDLCReport类的代码：

公共静态类PrintRDLCReport { 私有静态Logger logger = LogManager.GetCurrentClassLogger（）;

    private static int m_currentPageIndex;

      string fileNameExtension, Encoding encoding,

        m_streams.Add(stream);
        return stream;
    }

        // A start and end page of 0 means generate all pages.

        m_streams = new List<Stream>();
        report.Render("Image", deviceInfo, CreateStream,
           out warnings);
        foreach (Stream stream in m_streams)
            stream.Position = 0;

        if (print)
        {

    }


    // Handler for PrintPageEvents

                    e.PageBounds.Top - (int)e.PageSettings.HardMarginY,
                    e.PageBounds.Width,
                    e.PageBounds.Height);

            // Draw a white background for the report
            e.Graphics.FillRectangle(Brushes.White, adjustedRect);

            // Draw the report content
            e.Graphics.DrawImage(pageMetaFile, adjustedRect);

            // Prepare for next page.  Make sure we haven't hit the end.
            m_currentPageIndex++;
            e.HasMorePages = m_currentPageIndex < m_streams.Count;
        }
    }

    public static void Print()
    {
        if (m_streams == null || m_streams.Count == 0)
            throw new Exception("Error: no stream to print.");
        PrintDocument printDoc = new PrintDocument();
        if (!printDoc.PrinterSettings.IsValid)
        {
            throw new Exception("Error: cannot find the default printer.");
        }
        else
        {

            m_currentPageIndex = 0;
            printDoc.DefaultPageSettings.Landscape = true;
            printDoc.DefaultPageSettings.Margins.Left = 0;
            printDoc.DefaultPageSettings.Margins.Right = 0;
            printDoc.DefaultPageSettings.Margins.Top = 0;
            printDoc.DefaultPageSettings.Margins.Bottom = 0;
            printDoc.Print();
        }
    }

    public static void PrintToPrinter(this LocalReport report)
    {
        m_pageSettings = new PageSettings();
        ReportPageSettings reportPageSettings = report.GetDefaultPageSettings();

        m_pageSettings.PaperSize = reportPageSettings.PaperSize;
        m_pageSettings.Margins = reportPageSettings.Margins;

        Export(report);
    }

    public static void DisposePrint()
    {
        if (m_streams != null)
        {
            foreach (Stream stream in m_streams)
                stream.Close();
            m_streams = null;
        }
    }

    private static string ToInches(int hundrethsOfInch)
    {
        double inches = hundrethsOfInch / 100.0;
        return inches.ToString(CultureInfo.InvariantCulture) + "in";
    }
}

这是rdlc报表的属性（我本来不得不总是将其更改为Content and Copy才能使报表甚至发布）。

以下是我包含rdlc的发布设置：

发布时如何保留rdlc字体？
