Asp.Net MVC上传大于2MB的视频文件

Question

我有一个API解决方案(目标框架4.0)和一个MVC解决方案(目标框架4.5.1)的作业门户。在概要中，我需要上传视频，但我面临的问题是，我无法上传大小大于2MB的视频文件。所以，我在互联网上搜索，找到一个解决方案是改变web.config关于Api解决方案，

Web.config
<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpRuntime executionTimeout="108000" maxRequestLength="2147483647"/>
</system.web>
<system.webServer>
<!-- maxAllowedContentLength = 2GB (the value is in Bytes) -->
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="2147483647" />
</requestFiltering>
</security>
</system.webServer>

应用后出现同样的问题"Failed!远程服务器返回一个错误:(500)内部服务器错误。">

这里我的控制器代码MVC解决方案CandidateController

Api解决方案web配置文件"maxRequestLength"目标框架4.0不支持如果有人解决了我的问题，谢谢你在先进

添加此配置

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseKestrel(options =>
{
options.Limits.MaxRequestBodySize = 52428800; //50MB
});
