Question

How can I get an ASP.net web form (v3.5) to post a file using a plain old <input type='file' />?

I am not interested in using the ASP.net FileUpload server control.

In your aspx :

<form id='form1' runat='server' enctype='multipart/form-data'>  <input type='file' id='myFile' name='myFile' />  <asp:Button runat='server' ID='btnUpload' OnClick='btnUploadClick' Text='Upload' /> </form> 

In code behind :

protected void btnUploadClick(object sender, EventArgs e) {     HttpPostedFile file = Request.Files['myFile'];      //check file was submitted     if (file != null && file.ContentLength > 0)     {         string fname = Path.GetFileName(file.FileName);         file.SaveAs(Server.MapPath(Path.Combine('~/App_Data/', fname)));     } }
