【问题描述】：
我得到了可怕的Cannot use a leading .. to exit above the top directory.
不幸的是，它正在生成...某处？....超出我的控制。是否有工具可以帮助我找出它是在哪里生成的？甚至是超链接的实际文本？也许以某种方式进行智能跟踪？
是的，有一百万个谷歌搜索结果。我知道我需要解决什么问题，只是不知道问题实际发生在哪里。
我尝试覆盖渲染事件，然后通过从基础遍历控制树来对我可以找到的每个 HtmlLink 对象调用 ResolveClientURL，但这永远不会引发异常或做任何错误。它会不会只在base.render 期间死亡，因为我正在从/v5/plugins/dashboard 的页面调用ResolveClientURL，而基本页面在/v5/ 中？
这是我为手动调试而编写的代码。我希望这段代码会引发异常。
protected override void Render(HtmlTextWriter writer)
{
foreach (Control c in base.Controls)
{
Trace.Write("New base control");
var baseParent = c;// findBaseParent(c);
Trace.Write(baseParent.GetType().ToString());
renderChillunsRecursive(baseParent, 0);
}
base.Render(writer);
}
private int total;
private void renderChillunsRecursive(Control c,int depth)
{
var chilluns = c.Controls;
foreach (Control a in chilluns)
{
renderChillunsRecursive(a,depth +1);
total++;
}
string otherString = String.Empty;
if(c.GetType() == typeof(HtmlLink))
{
HtmlLink theLInk = ((HtmlLink) c);
otherString = theLInk.Href;
otherString += " - " + theLInk.ResolveClientUrl(theLInk.Href);
}
Trace.Write(String.Format("{0} - {1} - {2} - {3} - {4}",depth,total,c.GetType(),c.ToString(),otherString));
}

【问题讨论】：
-
您何时收到此错误？我们是在谈论生产站点，还是仍处于开发阶段？这个错误是什么时候开始出现的？
-
我认为这是递归时的“深度+1”——你不需要那个。
-
Win2k8 r2/iis7.5 预生产。这是全新安装。
-
深度 +1 只是我尝试的跟踪位的一小部分信息。
