Question

我正在尝试使用C＃打印服务器报告而不进行预览。该报告在WidowsXP中正常打印，但它在Windows 7和Windows 10的缩放视图中打印。以下是我的代码。

using System;
using System.IO;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Printing;
using System.Drawing.Imaging;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using Microsoft.Reporting.WinForms;

namespace Dahlawi.ManPower.Recruiting.Forms
{
public partial class FrmReportViewer1 : Form
{
    List<Metafile> m_ReportPages = new List<Metafile>();
    int m_ReportPageIndex = 0;

    public FrmReportViewer1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        PrintDocument objPrintDoc = new PrintDocument();

        objPrintDoc.PrintPage += PrintPageHandler;

        PrintDialog objPrintDiag = new PrintDialog();
        objPrintDiag.Document = objPrintDoc;

        DialogResult objDiagResult = default(DialogResult);
        objDiagResult = objPrintDiag.ShowDialog();

        if (objDiagResult == DialogResult.OK)
        {
            objPrintDoc.PrinterSettings = objPrintDiag.PrinterSettings;

            this.m_ReportPages = new List<Metafile>();

            this.m_ReportPageIndex = 0;

            this.reportViewer.ShowCredentialPrompts = false;
            this.reportViewer.ServerReport.ReportServerCredentials.NetworkCredentials = new System.Net.NetworkCredential("USER", "PASSWORD", "DOMAIN");

            this.reportViewer.ServerReport.ReportServerUrl = new Uri("http://SERVER/ReportServer");
            this.reportViewer.ServerReport.ReportPath = "/DMR/Candidate_Information";

            ReportParameter[] reportParameters = new ReportParameter[] { new ReportParameter("CandidateId", "16744") };
            reportParameters[0].Visible = false;
            this.reportViewer.ServerReport.SetParameters(reportParameters);
            this.reportViewer.RefreshReport();

            string deviceInfo = "<DeviceInfo>" + "<OutputFormat>emf</OutputFormat>" + "  <PageWidth>8.5in</PageWidth>" + "  <PageHeight>11in</PageHeight>" + "  <MarginTop>0.2in</MarginTop>" + "  <MarginLeft>0.5in</MarginLeft>" + "  <MarginRight>0.5in</MarginRight>" + "  <MarginBottom>0.2in</MarginBottom>" + "</DeviceInfo>";

            Warning[] objWarnings = null;
            string[] sStreamIDs = null;
            string sMimeType = "";
            string sEncoding = "";
            string sFilenameExtension = "";

            byte[] renderedPage = null;

            renderedPage = this.reportViewer.ServerReport.Render("Image", deviceInfo, out sMimeType, out sEncoding, out sFilenameExtension, out sStreamIDs, out objWarnings);
            this.m_ReportPages.Add(new Metafile(new MemoryStream(renderedPage)));

            foreach (string sStreamId in sStreamIDs)
            {
                renderedPage = this.reportViewer.ServerReport.RenderStream("Image", sStreamId, deviceInfo, out sMimeType, out sEncoding);
                this.m_ReportPages.Add(new Metafile(new MemoryStream(renderedPage)));
            }

            objPrintDoc.Print();

            objPrintDoc = null;
        }
    }

    private void PrintPageHandler(object sender, PrintPageEventArgs e)
    {
        if (this.m_ReportPageIndex < this.m_ReportPages.Count)
        {
            Metafile imgPage = this.m_ReportPages[this.m_ReportPageIndex];

            this.m_ReportPageIndex += 1;

            e.Graphics.DrawImage(imgPage, 0, 0, imgPage.Width, imgPage.Height);

            e.HasMorePages = this.m_ReportPageIndex < this.m_ReportPages.Count;
        }
    }
}

}

当我在WindowsXP中使用上述代码打印报告时，它会打印出这样的Proper Print

但是，当我在Windows 7或Windows 10中运行相同的代码时，它会打印出像Zoomed Print

这样的代码

请帮我在Windows 7 / Windows 10上运行此代码。如果需要，我可以提供更多详细信息。

我发现了这个问题并且它是＆＃34; emf＆＃34;输出格式导致Windows 7和Windows 10上的问题，但在Windows XP / Windows 2003上正常工作。我在＆＃34; deviceInfo＆＃34;中更改了输出格式。来自＆＃34; emf＆＃34;的字符串到＆＃34; jpg＆＃34; （其他格式，例如＆＃34; png＆＃34;，＆＃34; jpeg＆＃34;，＆＃34; bmp＆＃34;也可以正常工作）然后我更改了＆＃34; m_ReportPages＆＃34;来自＆＃34; Metafile＆＃34;的列表对象to＆＃34; Image＆＃34;并解决了问题。

打印服务器报告，无预览显示缩放报告
