This setting goes in your web.config file. It affects the entire application, though... I don't think you can set it per page.

"xxx" is in KB. The default is 4096 (= 4 MB).

I know it is an old question.

So this is what you have to do:

In you web.config file, add this in <code>&lt;system.web&gt;</code>:

<pre class="lang-xml prettyprint-override"><code>&lt;!-- 3GB Files / in kilobyte (3072*1024) --&gt;
&lt;httpRuntime targetFramework="4.5" maxRequestLength="3145728"/&gt;
</code></pre>

and this under <code>&lt;system.webServer&gt;</code>:

<pre class="lang-xml prettyprint-override"><code>&lt;security&gt;
 &lt;requestFiltering&gt;

 &lt;!-- 3GB Files / in byte (3072*1024*1024) --&gt;
 &lt;requestLimits maxAllowedContentLength="3221225472" /&gt;

 &lt;/requestFiltering&gt;
&lt;/security&gt;
</code></pre>

You see in the comment how this works. In one you need to have the sie in bytes and in the other one in kilobytes. Hope that helps.

Max file size can be restricted to a single MVC Controller or even to an Action. 
web.config &lt;location&gt; tag can be used for this:

<pre><code>&lt;location path="YourAreaName/YourControllerName&gt;/YourActionName&gt;"&gt;
 &lt;system.web&gt;
 &lt;!-- 15MB maxRequestLength for asp.net, in KB 15360 --&gt;
 &lt;httpRuntime maxRequestLength="15360" /&gt;
 &lt;/system.web&gt;
 &lt;system.webServer&gt;

 &lt;!-- 15MB maxAllowedContentLength, for IIS, in bytes 15728640 --&gt;

 &lt;/requestFiltering&gt;
 &lt;/security&gt;

If it works in your local machine and does not work after deployment in IIS (i used Windows Server 2008 R2) i have a solution. 

Open IIS (inetmgr)
Go to your website
At right hand side go to Content (Request Filtering)
Go to Edit Feature Settings
Change maximum content size as (Bytes you required)
This will work.

I have a form that excepts a file upload in ASP.NET. I need to increase the max upload size to above the 4 MB default.

I have found in certain places referencing the below code at <a href="http://msdn.microsoft.com/en-us/library/system.web.configuration.httpruntimesection.maxrequestlength.aspx" rel="noreferrer">msdn</a>. 

<pre><code>[ConfigurationPropertyAttribute("maxRequestLength", DefaultValue = )]
</code></pre>

None of the references actually describe how to use it, and I have tried several things with no success. I only want to modify this attribute for certain pages that are asking for file upload.

Is this the correct route to take? And how do I use this?

How to increase the max upload file size in ASP.NET?

Windows Server

我有一个表单，除了ASP.NET中的文件上传。我需要增加最大上传大小，以超过4MB的默认值。我发现在某些地方引用了上的以下代码。[ConfigurationPropertyAttribute("maxRequestLength", DefaultValue = )]没有一个参考文献实际描述了如何使用它，我已经尝试了几种方法，但都没有成功。我只想修改此属性的某些页面，是要求文件上传。这是正确的路线吗
