In fact I changed the code that I had used to send a simple message to another host (writing the received data to a text file) in order to meet my requirements. Although when I implement this revised code, there is no error and it seems to transfer correctly, I am not sure whether this is a correct way to do this transmission or not. Since I'm

问题 My ASP.NET application allows users to upload and download large files. Both procedures involve reading and writing filestreams. What should I do to ensure the application doesn't hang or crash when it handles a large file? Should the file operations be handled on a worker thread for example? 回答1: Make sure you properly buffer the files so that they don't take inordinate amounts of memory in the system. e.g. excerpt from a download application, inside the while loop that reads the file: //
