Javascript客户端代码：

function upload() {
  var formData = new FormData();
  var totalFiles = document.getElementById("FileUpload").files.length;

  for (var i = 0; i < totalFiles; i++) {
    var file = document.getElementById("FileUpload").files[i];

    formData.append("FileUpload", file);
    formData.append("guid", theGuid);
  }

  $.ajax({
    type: 'post',
    url: '/myController/Upload',
    data: formData,
    dataType: 'json',
    contentType: false,
    processData: false,
    success: function (response) {
      alert('succes!!');
    },
    error: function (error) {
      alert("errror");
    }
  });
}

在服务器端：

Request.Form["guid"];
Request.Files["FileUpload"];
