线程在水晶报表中被异常终止 [英] Thread was being aborted exception in crystal reports

问题描述

我们用来将报表导出为PDF的下面的代码。

  Response.Buffer = true; 
 Response.ClearContent（）; 
 Response.ClearHeaders（）; 
 Response.ContentType =application / pdf; 
 myReportDoc.ExportToHttpResponse（ExportFormatType.PortableDocFormat，Response，true，Session [ReportName]。ToString（））; 
 Response.Flush（）; 
 Response.Close（）; 
  

请帮助我解决此异常。

解决方案

SAP 解释说：

原因

$ b

问题已在问题报告ID ADAPT00765364 下识别并记录。
错误可能是因为 ExportToHttpResponse（）方法中使用了 Response.End（）

这是一个已知的问题， Reponse.End（）导致线程中止。这是设计。

有关详细信息，请参见 Microsoft KB312629文章。 / p>

解决方法

  .... 
 try 
 {
 reportDocument.ExportToHttpResponse（format，Response，true，Page.Title）; 
} 
 catch（System.Threading.ThreadAbortException）
 {
} 
 .... 
  

分辨率

您可以编写自己的代码，将Crystal报表直接导出到浏览器， PDF，Word，Excel等。您必须确保使用适当的内容类型。

示例代码将Crystal Report以PDF格式导出到网络浏览器

  try 
 {
 boReportDocument.Load（Server.MapPath（@MyReport.rpt））; 
 System.IO.Stream oStream = null; 
 byte [] byteArray = null; 
 oStream = boReportDocument.ExportToStream（ExportFormatType.PortableDocFormat）; 
 byteArray = new byte [oStream.Length]; 
 oStream.Read（byteArray，0，Convert.ToInt32（oStream.Length  -  1））; 
 Response.ClearContent（）; 
 Response.ClearHeaders（）; 
 Response.ContentType =application / pdf; 
 Response.BinaryWrite（byteArray）; 
 Response.Flush（）; 
 Response.Close（）; 
 boReportDocument.Close（）; 
 boReportDocument.Dispose（）; 
 
} 
 catch（Exception ex）
 {
 string s = ex.Message; 
} 
  

We were getting the Thread was being aborted Exception while exporting a report into PDF.

The below code we were using for export a report into PDF.

                    Response.Buffer = true;
                    Response.ClearContent();
                    Response.ClearHeaders();
                    Response.ContentType = "application/pdf";
                    myReportDoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, Session["ReportName"].ToString());
                    Response.Flush();
                    Response.Close();

Please help me how to resolve this exception.

解决方案

SAP explains that:

Cause

The issue has been identified and logged under Problem Report ID ADAPT00765364. The error is likely caused because Response.End() is used inside the ExportToHttpResponse() method.
It is a known issue that Reponse.End() causes the thread to abort. This is by design.
See Microsoft KB312629 Article for more info.

Workaround

....
 try
   {
   reportDocument.ExportToHttpResponse(format, Response, true, Page.Title);
   }
 catch (System.Threading.ThreadAbortException)
   {
   }
....

Resolution

You can write your own code to export a Crystal Report directly to the browser in a format such as PDF, Word, Excel, etc. You must make sure you use the appropriate content type.

Sample code to export Crystal Report to web browser as PDF

try
{
 boReportDocument.Load(Server.MapPath(@"MyReport.rpt"));
 System.IO.Stream oStream = null;
 byte[] byteArray = null;
 oStream = boReportDocument.ExportToStream (ExportFormatType.PortableDocFormat);
 byteArray = new byte[oStream.Length];
 oStream.Read(byteArray, 0, Convert.ToInt32(oStream.Length - 1));
 Response.ClearContent();
 Response.ClearHeaders();
 Response.ContentType = "application/pdf";
 Response.BinaryWrite(byteArray);
 Response.Flush();
 Response.Close();
 boReportDocument.Close();
 boReportDocument.Dispose();

}
catch (Exception ex)
{
 string s = ex.Message;
}
