How to check the uploaded fles contenttype??

Ex: If I have a fileupload component named FileUpload1, I need to check whether it's an excel file. What would be the way??

Mark this as answer, if it is.....

0	You would check the file extension to see if it matches a file type. You can get the file extension out of a path by using the Path.GetExtension() method: http://msdn.microsoft.com/en-us/library/system.io.path.getextension.aspx Something like this: Using System.IO; // ... string fileExt = Path.GetExtension(FileUpload1.FileName); if(fileExt.Equals(".xls") \|\| fileExt.Equals(".xlsx")) { // excel file type } Nishithraj, if this helps please login to Mark As Answer. \| Alert Moderator

Something like this:

Using System.IO;

// ...

string fileExt = Path.GetExtension(FileUpload1.FileName);

if(fileExt.Equals(".xls") || fileExt.Equals(".xlsx"))

{

   // excel file type

}
