您是否在Web.Config文件中使用适当的值设置了HttpRuntime元素?对于如此大的文件，这将花费更多时间，因此您需要在此之前保持请求/响应有效，并增加请求的大小.

阅读:
httpRuntime元素(ASP.NET设置架构) [

Have you set the HttpRuntime element with proper values in Web.Config file? For such big files it will take more time and thus you need to keep the request/response alive till then and also increase the size of request.

Read:
httpRuntime Element (ASP.NET Settings Schema)[^]

You would need to increase executionTimeout & maxRequestLength

Even after doing these, if there is some error/issue tell us what it is.
