推荐答案

你需要允许大文件通过将文件大小值分配给 maxRequestLength 属性 httpRuntime 标记。



参见设置Web.config以允许ASP .NET应用程序上载大文件 [ ^ ]

You need to allow large files by assigning file size value to maxRequestLength property of httpRuntime Tag.

See Setting up Web.config to allow uploading of large files by ASP .NET applications[^]
