route to record a txt file, into a folder on the C drive on a client pc, its a web app in c # asp.net

Hello,

As far as I know there is no easy solution to write directly a file on the client PC. This actually makes sense as it is a security issue, virus writer would love that feature!

What you can do is popup a save as dialog that asks the user to save a file.

Here is an example of how you can do this:

protected void ButtonGetPeople_Click(object sender, EventArgs e)
{
    Response.Clear();
    Response.AddHeader("content-disposition", "attachment; filename=" + _exportfileName);
    Response.AddHeader("content-type", "text/csv");

    using (StreamWriter writer = new StreamWriter(Response.OutputStream))
    {
        writer.WriteLine("Name,DoB,Add1,Add2,Add3,Add4");
        // ... export all the data....
    }
    Response.End();
}

Valery.
