Hi Try this code : if (FileUpload1.HasFile) { string extension = System.IO.Path.GetExtension(FileUpload1.FileName); if (extension == .jpg ) { FileUpload1.SaveAs( yourpath + FileUpload1.FileName); } else { Response.Write( Only .Jpg allowed ); } } Reference : https://forums.asp.net/t/1411282.aspx?Fileupload+Control+Allow+only+for+image+files http://www.aspdotnet-suresh.com/2015/10/aspnet-fileupload-validate-file-extension-to-allow-only-images-example-in-csharp-vbnet.html

Try Like below: Using Expression: asp:FileUpload ID = fuImportImage runat = server /> asp:RegularExpressionValidator ID = regexValidator runat = server ControlToValidate = fuImportImage ErrorMessage = Only JPEG images are allowed ValidationExpression = (.*\.([Jj][Pp][Gg])|.*\.([Jj][Pp][Ee][Gg])$) > asp:RegularExpressionValidator > Using Accept attribute asp:FileUpload ID = fileUploader runat = server accept = .png.jpg.jpeg.gif /> Using C# string fileExtn = System.IO.Path.GetExtension(FileUpload1.FileName) if (fileExtn == jpeg ) { Lbl.text = File format is correct ; } else { Lbl.text = Upload correct file format ; }
