helo,

I designed the html form.so i specified one input as file.When i browse for a specific file that path appears in the browse text when i click submit it is transfering file or path...
I designed the form like this

@using (Html.BeginForm("Details", "Home", FormMethod.Post, new { id = "Form" })) 
{
    <input type="file" name="file" />
    <input type="submit" value="submit" />
}

so it transfers the file or path to the controller and my controller is Home/Details so it transfers the file or path if it is path please provide me solution to transfer the file..
