使用ASP上传文件(最多10Mb文件大小)。净webAPI

I work on a VS2012 MVC4 project containing a Web API controller. This project will be published on an IIS server.

我在一个VS2012 MVC4项目中工作，该项目包含一个Web API控制器。此项目将在IIS服务器上发布。

I need to allow users to upload files. The problem is a web API is limited up to 4MB maximum file size upload. I read (for example here: http://blogs.msdn.com/b/henrikn/archive/2012/03/01/file-upload-and-asp-net-web-api.aspx) that we can extend this limitation by self hosting the web API (in this case file upload up to 2GB). I don't want self host my webAPI because I want to host it on my IIS web server so I think this is not suitable for my situation, right? So what can I do for uploading files bigger than 4MB?

我需要允许用户上传文件。问题是web API的最大上传文件大小限制为4MB。我读过(例如:http://blogs.msdn.com/b/henrikn/archive/2012/03/03/01/03/01/03/01/03/01/03/01/03/01/03/01/03/01/01/01/03/01/03/03/01/03/01/03/01/03/01/03/01/03/01/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/03/01/01/我不想让self托管我的webAPI因为我想把它托管在我的IIS web服务器上所以我认为这不适合我的情况，对吧?那么，对于上传大于4MB的文件，我能做些什么呢?

If possible I search for an HTML5 solution (with drag'n drop).

如果可能的话，我搜索HTML5解决方案(拖拽)。

So far none of the solutions I found allows me to accomplish this.

到目前为止，我所找到的解决方案中没有一个能让我做到这一点。

Thanks for your help.

Probably it was not clear but actually the blog url is referring to IIS. You need to look for the following 2 settings in Web.config to increase the upload size:

可能不清楚，但实际上博客url指的是IIS。您需要在Web中查找以下两个设置。增加上传大小:

NOTE(maxRequestLength="size in kbytes"):
<system.web> <httpRuntime targetFramework="4.5" maxQueryStringLength="" maxRequestLength="" maxUrlLength="" />

注意(maxRequestLength =“kb大小”): <系统。 "

NOTE(maxAllowedContentLength is in bytes) <system.webServer> <security> <requestFiltering> <requestLimits maxAllowedContentLength="" maxQueryString="" maxUrl=""/>

注意(maxAllowedContentLength以字节为单位) <系统。webserver> < requestfilter > < requestlimitmaxallowedcontentlength ="" maxQueryString="" maxUrl="" ""/>

If you read it carefully, it says "ASP.NET has a maximum limit of 2G in terms of file size that you can upload." So basically when hosted in ASP.NET/IIS you will be able to receive files up to 2Gbs. What you have to do is change some default values in web.config.

如果你仔细阅读，它会说“ASP”。NET对于你可以上传的文件大小有2G的最大限制。在ASP中托管的时候。NET/IIS您将能够接收到最多2Gbs的文件。您需要做的是在web.config中更改一些默认值。

You can check this

你可以检查这个

 int MaxContentLength = 1024 * 1024 * 10; //Size = 10 MB
if (postedFile.ContentLength > MaxContentLength)
{
