How to get Content (MIME) Type of the Uploaded File in ASP.Net

This way

string contentType = FileUpload1.PostedFile.ContentType;

Sorry Mudassar but I do not understand your answer.

In your sample you specify:

contenttype="application/vnd.ms_excel" for Excel files

contenttype="application/vnd.ms_word" for word file

My questions is: what will be the contenttype for txt files

Thanks

Hi

Content type for text file:-"text/plain"

The code I have given will automatically get the content type of file from browser
