发生类型为'System.StackOverflowException'的未处理异常-使用Cache'd类 [英] An unhandled exception of type 'System.StackOverflowException' occurred - using Cache'd class

问题描述

我有一个如下课程:

I have a class as in the following:

public class activityDetail
{
  public string a { get; set; }
  public string b { get; set; }
}

然后我想做的就是在Cache.cs中定义一个singlton类，如下所示:

then what I want to do is define a singlton class in my Cache.cs as in the following:

public sealed class Cache
{
private static  readonly Cache cacheInstance = new Cache();
.
.
.
.
public activityDetail instanceofActivitydetail { get { return instanceofActivitydetail; } }

现在，在我的控制器中，我想引用此instanceofActivitydetail，如果我通过以下方式获取异常(某种类型的堆栈溢出)的方式进行引用:

Now, in my controller I want to reference this instanceofActivitydetail, if I do it the following way I get an exception (some type of stack overflow):

Cache.CacheInstance.instanceofActivitydetail.a = some value; 
Cache.CacheInstance.instanceofActivitydetail.b = some other value;

//一些值"只是为了简便起见，它实际上具有指定的已知值，但在此处共享它并不容易.
//因此，当编译器在每一行中均引发上述错误时，我认为我在Cache类中的定义丢失了某些内容，或者我在控制器上显示的上述调用丢失了某些内容.

// "some value" is just for ease it actually have a designated known value but it is not easy to share it here.
// so when the compiler eaches this line it throws the error mentioned above, I believe my defninition in the Cache class is missing something, or my call shown above from the controller is missing something.

推荐答案

此异常是最容易确定和修复的异常之一.几乎总是与未完成的递归或相互递归有关:

This exception is one of the easiest to nail down and fix. Almost always, it is related to unfinished recursion or mutual recursion:
http://en.wikipedia.org/wiki/Recursion[^],
http://en.wikipedia.org/wiki/Mutual_recursion[^].

Use the debugger, put a breakpoint where the exception is thrown. You will observe that the code is repeated many times in execution. To see where a call comes from, use "Call stack" debugger window. When you see what the calling code is repeated, move your breakpoint there, until you see the root of the problem.

公共活动详细信息instanceofActivitydetail {get;设置；}

并将以下内容放入控制器中(在使用Cache类/属性之前):

Cache.CacheInstance.instanceofActivitydetail = new activityDetai();

public activityDetail instanceofActivitydetail { get; set;}

and placed the following in the controller (before using the Cache class/property):

Cache.CacheInstance.instanceofActivitydetail = new activityDetai();
