A new overload is added to the TransmitFile method of the HttpResponse class in ASP.NET 2.0

View products that this article applies to.

Summary

A new overload for the TransmitFile method of the HttpResponse class is included in Microsoft ASP.NET 2.0. This new overload lets you specify an offset in the file. The new overload also lets you obtain the number of bytes to be sent.

The following shows the format of the new overload:

HttpResponse.TransmitFile(String Filename, long offset, long length)

Note

Filename is a placeholder for the name of the file to be written to the HTTP output.
Offset is a placeholder for the start position in the file.
Length is a placeholder for the total length to be transmitted.

If you specify 0 as the Offset parameter and -1 as the length parameter, the whole file is sent.
