我正在使用Crystal Report（版本13.0）和.NET Framework 4.0以及VS 2013开发一个简单的应用程序 . 我正在做的是我在表单上有一个Crystal报表查看器，它应该在按钮时显示/加载我的报表点击 . 我加载报告的代码是：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
namespace CystalReportsApp
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                ReportDocument rpt = new ReportDocument();
                rpt.Load(@"e:<path>\CystalReportsApp\CystalReportsApp\CrystalReport1.rpt");
                crystalReportViewer1.ReportSource = rpt;
                crystalReportViewer1.Refresh();
            }
            catch (Exception ex)
            {

                throw;
            }
        }
    }
}

Problem i am getting is that whenever i click button, an exception occurs saying this:

CrystalDecisions.Shared.CrystalReportsException was unhandled

Solutions i have tried are:

  • 一次又一次检查路径 .

  • 检查临时文件夹以及报告所在文件夹的文件权限 .

  • 检查stackoverflow的答案，但无法查看详细信息 .

但一切都在静脉中 . 有人可以告诉我幕后的情况吗？

UPDATED 除了这个论坛之外，我还在SAP crystal reports'论坛上发布了这个问题，有人回答说只是从路径中删除@符号 . 但是当我删除@符号时，"Unrecognized escape sequence"错误就会出现 . 请帮忙！ Answer by SAP COMMUNITY NETWORK

    试试：

    卷筒纸

    rpt.Load(Server.MapPath("\\CystalReportsApp\\CrystalReport1.rpt"))

    视窗

    rpt.Load(@"e:\\users\\shahid sultan minhas\\documents\\visual studio 2013\\Projects\\CystalReportsApp\\CystalReportsApp\\CrystalReport1.rpt")

    MySql.Data.MySqlClient.MySqlDataAdapter myAdapter1 = new MySql.Data.MySqlClient.MySqlDataAdapter(ds.Tables[0].Rows[0]["Query"].ToString(), conn);
                    myAdapter1.Fill(myData);
                    WaitSumCrystalReport3 myr = new WaitSumCrystalReport3();
                    myr.SetDataSource(myData);
                    if (myData.Tables[0].Rows.Count > 0)
                        myr.PrintToPrinter(1, true, 1, 10);
                    cmd.CommandText = "Update tbl_print set Status='1' where ID='" + ds.Tables[0].Rows[0]["ID"].ToString() + "'";
                cmd.Connection = conn;
                cmd.ExecuteNonQuery();
//disposing the crystal report object to clear the temp memroy.. otherwise memory is overflow occurs in future
                    myr.Dispose();
//above statement is used to dispose... it will work fine

    你的问题（比如我的）可能仍然与RPT文件的路径有关 . 在.aspx Web窗体中，您可能会受益于此语法：

    <CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
        <Report FileName="~/MyCrystalReport.rpt">
        </Report>
    </CR:CrystalReportSource>

    通过使用相对路径，我可以在经过多个小时的反复试验后执行我的报告文件 .

    cryRpt.Load（Path.Combine（AppDomain.CurrentDomain.BaseDirectory，“CrystalReport1.rpt”））;

    并右键单击CrystalReport1.rpt goto属性并将Build Action设置为Content，将CopyOutputDirectory设置为Copy for new ..
