Getting MIME Type (Content Type) of a File using C# and VB.Net

First, the path of the file is passed as parameter to GetFileName method of Path class which gives the name of the file.
Finally, the file name is passed as parameter to GetMimeMapping method of MimeMapping class which determines the MIME type or the Content Type of the file.
C#
string word = MimeMapping.GetMimeMapping(Path.GetFileName(Server.MapPath("~/Files/sample.docx")));
string excel = MimeMapping.GetMimeMapping(Path.GetFileName(Server.MapPath("~/Files/sample.xlsx")));
string pdf = MimeMapping.GetMimeMapping(Path.GetFileName(Server.MapPath("~/Files/sample.pdf")));
string image = MimeMapping.GetMimeMapping(Path.GetFileName(Server.MapPath("~/Files/sample.png")));
 
VB.Net
Dim word As String = MimeMapping.GetMimeMapping(Path.GetFileName(Server.MapPath("~/Files/sample.docx")))
Dim excel As String = MimeMapping.GetMimeMapping(Path.GetFileName(Server.MapPath("~/Files/sample.xlsx")))
Dim pdf As String = MimeMapping.GetMimeMapping(Path.GetFileName(Server.MapPath("~/Files/sample.pdf")))
Dim image As String = MimeMapping.GetMimeMapping(Path.GetFileName(Server.MapPath("~/Files/sample.png")))
