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，它应该显示/加载我的单击按钮时报告。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;
}
}
}
}
我得到的问题是，每当我点击按钮时，会发生异常，说：
CrystalDecisions.Shared.CrystalReportsException was unhandled
HResult=-2146232832
Message=Load report failed.

您的问题（如我的）可能仍与RPT文件的路径有关。在.aspx Web窗体中，您可以从这种语法中受益：
<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。

就我而言，我首先得到一个错误：Could not load file or assembly 'CrystalDecisions.ReportAppServer.ClientDoc', Version=xxx'。然后我找到并添加对 xxx version of CrystalDecisions.ReportAppServer.ClientDoc.dll 的引用，然后运行程序，出现新错误 Load Report Failed。
询问我的同事后，我转到Project > Properties > Build，并取消选中Prefer 32-bit 复选框，然后恢复使用我使用的原始版本CrystalDecisions.ReportAppServer.ClientDoc.dll，然后我可以成功生成报告。
此外我已经安装了 64 位版本的 Crystal Reports runtime engine。
