问题 Quoted from MSDN entry for TransmitFile: The maximum number of bytes that can be transmitted using a single call to the TransmitFile function is 2,147,483,646, the maximum value for a 32-bit integer minus 1. The maximum number of bytes to send in a single call includes any data sent before or after the file data pointed to by the lpTransmitBuffers parameter plus the value specified in the nNumberOfBytesToWrite parameter for the length of file data to send. If an application needs to transmit

Trouble with Response.WriteFile / Response.BinaryWrite / Response.TransmitFile (ASP.NET)

问题 I've got a simple web-page that generates a CSV file that I want the user to be able to download once its creation is complete. Here's a summary of my situation: The CSV file can be created in-memory or on disk. Doesn't matter to me. Once I'm done transmitting the CSV file, I do not want it to continue residing on disk. I've tried various code using Response.WriteFile, .TransmitFile, .BinaryWrite and .Write, but to no avail. When I say "to no avail" , I mean that rather than the CSV file

问题 I have a 5Mb pdf on the server dowloading this file using a writeFile gives me a 15Mb download, where as the transmitfile gives the correct 5Mb filesize... Is this due to some sort of uncompression into memory on the server for the writeFile? Just wonder if anyone had seen the same thing happening... (ps only noticed it since we went to iis7??) code being... if (File.Exists(filepath)) { HttpContext.Current.Response.Clear(); HttpContext.Current.Response.ContentType = "application/octet-stream"

问题 I'm facing a very strange problem in my ASP.NET Application. When the user clicks the button that downloads a file, Internet Explorer / Chrome / Firefox shows the save dialog but the name of the file is the name of the ASPX Page (For example, if the page is named Download.aspx the download dialog shows the "file" Download.zip). Sometimes, when playing with MIME type the download dialog shows "Download.aspx". Seems that you're trying to download the page, but actually is the correct file. This
