我搜索了如何使用 asp.net 将大于 4MB 的大型视频保存并存储到数据库中。我尝试了很多代码。我也用过：
<httpRuntime maxRequestLength="102400" executionTimeout="3600" />
<security >
<requestFiltering>
<requestLimits maxAllowedContentLength="1024000000" />
</requestFiltering>
</security>
这不是工作。它向我显示消息：
超时过期。操作完成之前的超时时间或服务器没有响应
到目前为止，我将数据列更改为 varbinary(MAX) 但我无法存储大小为 100MB 的大文件。
