如何修复.NET中的StackOverFlowException [英] How to fix StackOverFlowException in .NET

问题描述

ASP .NET 4.6 MVC控制器在运行时创建Razor模板，并使用RazorEngine运行它.
从Visual Studio运行时，一个大模板会导致堆栈溢出异常.从Mono运行时， Method CompiledRazorTemplates.Dynamic.dbcfcaeeb:Execute()太复杂..

如果从模板中删除了大量的div，它将编译并运行正常.

如何解决此问题?如何增加净堆栈大小或其他任何想法?

导致此问题的剃刀模板有2880行.它包含228个变量和很多div:

  @inherits Reporting.ReportTemplateBase< MYApp.ViewModels.RazorViewModel><！DOCTYPE html>< html>....<身体>@ {动态Vrapopref = ko.Keel;动态Vymardada = Iif(Ko.Ymardus == 1,2，Iif(Ko.Ymardus == 2,0,1));动态Vjag = Iif(Ko.Ymardus！= 3,1,1000);动态V4gr = true;动态Vs41gr = 0;动态Vs42gr = 0;...动态_calculated229 = Round(Vs52gr/Vjag * Iif(Core.Left(r.BilskeemKontoklass，1)=="K"，-1,1)，Vymardada);_calculated229 = SetDefault(_calculated229);}< div class ='row'style ='最小高度:0.45cm'>< div class ='field'style ='@ TextBox(0.00,0.66,7.37,0.45); font-family:"Arial"; font-weight:bold;'> @@ try {WriteLiteral(Out(Eeva.Business.Prpalk.GetSfirmanimi());)catch(Exception ex){LogiVormiViga("Out(Eeva.Business.Prpalk.GetSfirmanimi())"，ex);}}</div></div>< div class ='row'style ='min-height:0.03cm'>< div class ='field'style ='@ TextBox(0.00,1.87,2.39,0.45); font-family:"Arial"; font-size:9pt;'> @ {try {WriteLiteral(Out(Ise.Regnr));} catch(Exception ex){LogiVormiViga("Out(Ise.Regnr)"，ex);}}</div></div>< div class ='row'style ='min-height:0.42cm'>< div class ='field'style ='left:0.66cm; font-family:"Arial"; font-size:9pt;'> @Raw(IR("Reg nr"))</div></div>< div class ='row'style ='min-height:0.71cm'>< div class ='field'style ='@ TextBox(0.00,0.66,7.74,0.55); font-family:"Arial"; font-size:9pt;'> @@ try {WriteLiteral(Out(RTrim(Ise.Tanav)+" + RTrim(Ise.Piirkond)+" + RTrim(Ise.Postiindek)));} catch(Exception ex){LogiVormiViga("Out(RTrim(Ise.Tanav)+ \" \"+ RTrim(Ise.Piirkond)+ \"\" + RTrim(Ise.Postiindek))，ex);}}</div></div>< div class ='row'style ='min-height:0.71cm'>< div class ='field'style ='左:0.66cm; font-family:"Arial"; font-size:16pt; font-weight:bold;'> @Raw(IR("TULEMIARUANNE KUUDE KAUPA"))</div></div>< div class ='row'style ='最小高度:0.39cm'>< div class ='field'style ='@ TextBox(0.00,0.66,4.00,0.42); font-family:"Arial"; font-size:9pt; font-weight:bold;'> @ {try {WriteLiteral(Out(Format(Ko.Akuupaev，-"，Ko.Lkuupaev，"d"))));} catch(例外){LogiVormiViga("Out(Format(Ko.Akuupaev，\"-\，Ko.Lkuupaev，\"d \"))，ex);}}</div>...</body></html> 

整个模板位于

解决方案

这是一段时间以来我看到的最丑陋的代码.您应该重构它以使用数组或将计算结果移动到控制器.页面 太复杂了，这可能是Mono错误是正确的.

  dynamic _calculated21 = Round(r.Total/Vjag*Iif(Core.Left(r.BilskeemKontoklass，1)=="K"，-1,1)，Vymardada);_calculated21 = SetDefault(_calculated21);//大约有200条相似的行动态_calculated229 = Round(Vs52gr/Vjag * Iif(Core.Left(r.BilskeemKontoklass，1)=="K"，-1,1)，Vymardada);_calculated229 = SetDefault(_calculated229); 

再过一会儿:

  _calculated21 = SetDefault(_calculated217);//删除约200条相同的行_calculated229 = SetDefault(_calculated229); 

ASP .NET 4.6 MVC controller creates Razor Template at runtime and runs it using RazorEngine.
One big template causes Stack Overflow exception when running from Visual Studio or Method CompiledRazorTemplates.Dynamic.dbcfcaeeb:Execute () is too complex. when runing from Mono.

If large number of divs are removed from template, it compiles and runs OK.

How to fix this ? How to increase net stack size or any other idea ?

Razor template which causes this has 2880 lines. It contains 228 variables and lot of divs:

@inherits Reporting.ReportTemplateBase<MYApp.ViewModels.RazorViewModel>

<!DOCTYPE html>
<html>
....
<body>
    @{
    dynamic Vrapopref=ko.Keel;
dynamic Vymardada=Iif(Ko.Ymardus==1,2,Iif(Ko.Ymardus==2,0,1));
dynamic Vjag=Iif(Ko.Ymardus!=3,1,1000);
dynamic V4gr= true ;
dynamic Vs41gr=0;
dynamic Vs42gr=0;
...
dynamic _calculated229=Round(Vs52gr/Vjag*Iif(Core.Left(r.BilskeemKontoklass,1)=="K",-1,1),Vymardada);
_calculated229=SetDefault(_calculated229);

    }

解决方案

That's some of the ugliest code I've seen for a while. You should refactor it to use arrays or move the calculations to the controller. It might be the Mono error is correct, that the page is too complex.

dynamic _calculated21=Round(r.Total/Vjag*Iif(Core.Left(r.BilskeemKontoklass,1)=="K",-1,1),Vymardada);
_calculated21=SetDefault(_calculated21);

// about 200 similar lines snipped
dynamic _calculated229=Round(Vs52gr/Vjag*Iif(Core.Left(r.BilskeemKontoklass,1)=="K",-1,1),Vymardada);
_calculated229=SetDefault(_calculated229);

And a bit later:

_calculated21=SetDefault(_calculated217);
// about 200 identical lines removed
_calculated229=SetDefault(_calculated229);
