将多个文件发送到方法

Question

在下面的代码中我必须将所有文件发送到方法。我尝试了以下代码，它抛出文件不存在。请帮助我解决问题。

HttpFileCollection fileCollection = Request.Files;
for (int i = 1; i < fileCollection.Count; i++)
{
    HttpPostedFile uploadfile = fileCollection[i];
    string fileName = Path.GetExtension(uploadfile.FileName);
    //String extension = Path.GetExtension(uploadfile.FileName);
    FileHidden.Value = uploadfile.ToString();
    string Files= FileHidden.Value ;
}

FileUpload(sBatchName, Files);
