如何在Crystal Reports版本13.0中删除加载报告失败错误？

Question

我正在开发一个使用Crystal Report（版本13.0）和.NET Framework 4.0以及VS 2013的简单应用程序。我所做的是我在窗体上有一个Crystal报表查看器，用于显示/加载我的报表当按钮被点击时。我的代码加载报告：

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; 
      } 
     } 
    } 
} 

问题我得到的是，每当我点击按钮，发生异常时这样说：

解决方案我已经试过有：

1. 一次又一次地检查路径。
2. 检查临时文件夹以及我的报告所在的文件夹的文件权限。
3. 检查答案的stackoverflow，但无法找到有关我的问题的详细信息的答案。

但都是静脉曲张。有人可以告诉我，幕后发生了什么？

修订 除了这个论坛，我也张贴在SAP水晶报表论坛这人回答是刚刚从路径删除@符号这个问题。但是当我删除@符号时，出现“无法识别的转义序列”错误。请帮忙！ Answer by SAP COMMUNITY NETWORK

Answer 1

尝试：

网络

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

的Windows

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

Answer 2

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 

..

Answer 3

您的问题（像我）可能仍然是RELA指向RPT文件的路径。在.aspx Web窗体，您可能会受益于这种语法：

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

通过使用相对路径，我能够多小时的试错后，执行我的报告文件。

Answer 4

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

和CrystalReport1.rpt转到属性右键点击设置 生成操作内容和 CopyOutputDirectory复制是否有更新..

Answer 5

确保所有您的字段正确填充。

有一次，我遇到这样的问题，这在SQL查询消除误差以后解决
