如何将HttpError ConfigurationElement还原回"Inherited"(继承).使用IIS 7 API [英] How to revert an HttpError ConfigurationElement back to "Inherited" using IIS 7 API

问题描述

假设我在web.config中具有以下<httpErrors>集合:

<httpErrors>
</httpErrors>

是的，很好'n为空.

在IIS 7中，我的HTTP错误页面如下所示:

美丽！ (我之所以突出显示404是因为这是我将在几秒钟内使用的示例).

现在，我运行以下代码:

errorElement["statusCode"] = 404;
errorElement["subStatusCode"] = -1;
errorElement["path"] = "/404.html";
httpErrorsCollection.Add(errorElement);

可爱.现在，正如我在web.config中所期望的那样:

<httpErrors>
    <remove statusCode="404" subStatusCode="-1" />
    <error statusCode="404" subStatusCode="-1" prefixLanguageFilePath="" path="/404.html" />
</httpErrors>

再开心不过了.现在，在IIS 7中，"HTTP错误"部分按预期显示，如下所示:

在这一点上，生活再好不过了.现在，我想以编程方式将我的404错误还原为原始屏幕截图所示的状态.逻辑表明我应该remove我的新错误:

httpErrorsCollection.Remove(errorElement);

但是，如果我这样做，我的web.config看起来很像这样:

    <httpErrors>
        <remove statusCode="404" subStatusCode="-1" />
    </httpErrors>

我的IIS看起来像这样:

这是由于我的web.config而引起的-但是，如何使用ServerManager及其所有有用的IIS 7 API，完全删除httpError元素并将我的web.config还原为:

<httpErrors>
</httpErrors>

有什么想法吗?

解决方案

在IIS7及更高版本的管理部分下，我们可以看到一个名为配置编辑器的图标， 双击并扩展至

system.webserver-> webdav-> httpErrors

在

下的默认路径上

右键单击

部分->单击还原为父对象"

然后重新启动网站

所做的更改将被还原

Suppose I have the following <httpErrors> collection in a web.config:

<httpErrors>
</httpErrors>

Yep, nice 'n empty.

And in IIS 7, my HTTP errors page looks like this:

Beautiful! (I've highlighted 404 simply because that's the example I'll use in a sec).

Now, I run the following code:

errorElement["statusCode"] = 404;
errorElement["subStatusCode"] = -1;
errorElement["path"] = "/404.html";
httpErrorsCollection.Add(errorElement);

Lovely. I now have, as expected this in my web.config:

<httpErrors>
    <remove statusCode="404" subStatusCode="-1" />
    <error statusCode="404" subStatusCode="-1" prefixLanguageFilePath="" path="/404.html" />
</httpErrors>

Couldn't be happier. Now, in IIS 7 my HTTP errors section looks, as expected, like below:

Life couldn't be sweeter at this point. Now, down the line, I want to programmatically revert my 404 error back to the state shown in the original screenshot. Logic dictates that I should remove my new error:

httpErrorsCollection.Remove(errorElement);

But alas, if I do this, my web.config looks a lot like this:

    <httpErrors>
        <remove statusCode="404" subStatusCode="-1" />
    </httpErrors>

And my IIS looks a bit like this:

This is expected because of my web.config - but how, using ServerManager and all it's useful IIS 7 API, do I remove the httpError element entirely and revert my web.config back to:

<httpErrors>
</httpErrors>

Any ideas?

解决方案

In IIS7 and above under Management section, we can see an icon named Configuration Editor, double click and expand to

system.webserver-->webdav-->httpErrors

Right click on Default path, under

section-->Click on Revert to Parent

Then restart the website

The changes will be reverted back
