asp.net C#Crystal Report导出到PDF内存已满 [英] asp.net c# crystal report export to PDF memory full
问题描述
我正在使用Crystal Reports和VS2010构建报告:ASP.NET/C#相当大(使用OLE对象的页面为6页)，所以我不确定这是否是此问题的原因或解决方案，但是我需要知道如何解决此问题或替代方法.我以相同方式使用OLE对象构建的所有其他报告仍然可以正常导出.
I am building a report using Crystal Reports and VS2010: ASP.NET/C# which is fairly big (6 pages using OLE Objects), so I am not sure if that would be the cause or solution to this problem, but I need to know either how to fix this or an alternative. All other reports that I built using OLE Objects in the same manner still export just fine.
我正在使用的代码是:
protected void exportPDF_btn_Click(object sender, EventArgs e)
{
ReportDocument repDoc = getReportDocument(); //regathers the report
Response.Buffer = false;
Response.ClearContent();
Response.ClearHeaders();
try
{
repDoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, true, "filename");
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
ex = null;
}
finally
{
Response.End();
}
}
问题是我不断收到错误消息:
The problem is that I keep getting an error that says:
内存已满，无法导出报告，没有足够的内存用于 操作
Memory Full, Failed to export the report, Not enough memory for operation
我尝试过的其他解决方案:
Other solutions I have tried:
- 重置IIS
- 重新启动服务器
- 按照建议安装CutePDF: Crystal Report 2008-内存已满
-
将第三个参数从true更改为false会导致以下代码行:
- Resetting IIS
- Restarting Server
- Installing CutePDF as suggested: Crystal Report 2008 - Memory Full
Changing 3rd param from true to false resulting in this line of code:
repDoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat，Response，false，文件名");
repDoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, Response, false, "filename");
使用ExportToDisk而不是ExportToHttpResponse，导致 这段代码:
Using ExportToDisk as opposed to ExportToHttpResponse, resulting in this code:
repDoc.ExportToDisk(ExportFormatType.PortableDocFormat，@"Z:\ KFauver \ test \ file.pdf");
repDoc.ExportToDisk(ExportFormatType.PortableDocFormat, @"Z:\KFauver\test\file.pdf");
此报告是我最后要完成才能进行Beta测试的最后一项.但是，我现在对如何将其导出为PDF(或与此相关的任何内容)完全迷失了.任何帮助表示赞赏！无论是修复还是替代，都请尝试一下.预先感谢.
This report is one of the last items that I need to complete to finally be able to push to beta test. However, I am now officially lost as to how to export this to PDF (or anything for that matter). Any help is appreciated! Whether it be a fix or an alternative, ill try it. Thanks in advance.
推荐答案
显然，在报表上具有Word Doc OLE对象的6个实例将导致它需要太多内存.我没有意识到这一点.我的解决方法是拍摄每个页面的屏幕截图，然后将图像粘贴到报告中.似乎可以正常工作.
Apparently, having 6 instances of a word doc OLE object on a report will cause it to need too much memory. I did not realize this. My fix was to take screenshots of every page and paste the images into the report. Seems to work just fine that way.
