ASP. NET FileUpload

When using the ASP: FileUpload control in the asp. NET control, you sometimes need to upload large files. By default, the maximum size of uploaded files is 4 MB. How to implement it?
You only need to change the two default settings in the configuration file: maxRequestLength and requestLengthDiskThreshold in httpRuntime. The former specifies the maximum size of the upload, and the latter sets the cache size.
For example:
<Configuration>
<System. web>
...
<HttpRuntime maxRequestLength = "maximum size of uploaded files" requestLengthDiskThreshold = "cache size"/>
...
</System. web>
</Configuration>
