Automate file uploading in Asp.Net MVC application

I have some images in local folder. I want to grab those images and send them to certain action of the controller without user interactivity. So I do not have to use file up loader to upload files one by one.

I don't know how to automate this task.

I have seen this but its using automation tool.

View Code:

@using (Html.BeginForm("AddDriverOffence", null, FormMethod.Post, new
{ 
enctype = "multipart/form-data", 
@data_ajax = "false",
id = "ImgForm",
name = "ImgForm",
target = "UploadTarget",
role = "form"
}))
{

   <div class="form-group">
        @Html.LabelFor(model => model.File, new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.TextBoxFor(model => model.File, new { type = "file"})
            @Html.ValidationMessageFor(model => model.File)
            <input type="submit" id="upload" name="upload" value="Upload" class="cancel" />
        </div>
    </div>
}

Controller:

private string AddDriverOffence(HttpPostedFileBase file)
{
 // I want to grab image here
}
