水晶报告源路径动态 [英] crystal report source path dynamically

问题描述

大家好，这是我的第一个问题，这是个好问题,,,,

i有包含水晶报告的c＃应用程序，一切正常，除非我更改文件位置，否则会出错loading field

 ReportDocument rpt =  new  ReportDocument（）; 
 rpt.Load（  C：\\Users\\mypce \\Desktop \\ file \\CrystalReport1.rpt）; 
 crystalReportViewer1.ReportSource = rpt; 

所以我想要的是动态制作路径，或者我可以将此路径放在配置文件中，我可以随时更改， ,,

解决方案

您可以在配置文件中定义报告路径，如下所述：

http://stackoverflow.com/questions/13152765/declare-a-string-in-web-config-file [ ^ ]

如下面链接所述，使用以下代码：

 <   appsettings  >  
 <   add     key   =  dir   < span class =code-attribute> value   =  YourReportPathHereInProperFormat    /  >  
 <   / appsettings  >  

  string  dir = ConfigurationManager.AppSettings [  dir]。ToString（）; 

有关AppSettings的更多信息，请参阅以下文章：

Web.config文件 - ASP.NET [ ^ ]

谢谢。

感谢您的重播，我在申请中工作是为了网络吗？

然而我知道这是正确的答案，但我没有正确使用

i像这样使用它

  //   ReportDocument rpt = new ReportDocument（）;  
  string  crystalrp = ConfigurationManager.AppSettings [  cry]。ToString（）; 
 crystalReportViewer1.ReportSource = crystalrp; 

并没有效果抱歉，但你可以帮我解决这个问题吗，

  string  st = ConfigurationManager.AppSettings [  crystalrp< /跨度>]的ToString（）; 
 ReportDocument rpt =  new  ReportDocument（）; 
 rpt.Load（st）; 
 crystalReportViewer1.ReportSource = rpt; 

非常感谢你帮助,,,,

解决方案

You can simply define path of report in config file as discussed here:
http://stackoverflow.com/questions/13152765/declare-a-string-in-web-config-file[^]
As described at below link, use following code:

<appsettings>
    <add key="dir" value="YourReportPathHereInProperFormat" />
  </appsettings>

string dir = ConfigurationManager.AppSettings["dir"].ToString();

For more look into "AppSettings" at below article:
Web.config File - ASP.NET[^]
