如何阅读maxAllowedContentLength [英] How to read maxAllowedContentLength

问题描述

对于我的web应用程序，我有文件上传flash组件。我想处理在客户端的最大文件大小限制没有实际发送的文件服务器。所以我需要读取配置文件，该值以某种方式将其发送给客户端。我发现有些文章说，直接读取配置文件不解决方案，因为它可以在一大堆的地方进行更改。所以，应该有一定的API调用可能，但我无法找到任何...

 ＆LT; system.webServer＆GT;
    ＆LT;安全＆GT;
        ＆LT;＆的requestFiltering GT;
            ＆LT; requestLimits maxAllowedContentLength =1048576/＆GT;
        ＆LT; /＆的requestFiltering GT;
    ＆LT; /安全＆GT;
＆LT; /system.webServer>
 

解决方案

试试这个方法。

您可以更改基于配置文件的Web配置code的下方段

我的web.config一些看起来像

 ＆LT;＆的System.Web GT;
  ＆LT;的httpRuntime executionTimeout =30的maxRequestLength =100/＆GT;
 

在这里，您可以看到的maxRequestLength 被定义为100，可以从网页背后code更改

添加使用System.Web.Configuration;

现在写这篇code键更改的maxRequestLength

的价值

 配置配置= WebConfigurationManager.OpenWebConfiguration（〜）;
HttpRuntimeSection httpruntinesec =
    （HttpRuntimeSection）configuration.GetSection（System.Web程序/的httpRuntime）;
 

您可以使用httpruntinesce实例设置的值。

For my web app i have flash component for uploading files. I would like to handle max file size limit on client side without actual sending that file to server. So i need to read that value from config file somehow to send it to client. Some articles i had found said that reading directly config file is not solution, because it can be changed in whole lot of places. So there should be some API call probably, but i cannot find any...

<system.webServer>
    <security>
        <requestFiltering>
            <requestLimits maxAllowedContentLength="1048576" />
        </requestFiltering>
    </security>
</system.webServer>

解决方案

Try this way

You can change the below segment of code based on the web configuration in the config file

My web.config some look like

<system.web>
  <httpRuntime executionTimeout="30"  maxRequestLength="100"/>

Here you can see maxRequestLength is defined as 100 which can be changed from code behind page

Add using System.Web.Configuration;

Now write this code to change the value of maxRequestLength

Configuration configuration = WebConfigurationManager.OpenWebConfiguration("~");
HttpRuntimeSection httpruntinesec =
    (HttpRuntimeSection)configuration.GetSection("system.web/httpRuntime");

You can use httpruntinesce instance set the value.
