我正在編寫一個C#ASP.Net MVC應用程序,以便客戶端將文件發佈到其他服務器。我使用通用處理程序來處理從客戶端到服務器的發佈文件。但在我的處理程序中,System.Web.HttpContext.Current.Request.Files始終爲空(0計數)。Request.Files始終爲空
表格代號:
@model ITDB102.Models.UploadFileResultsModels
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
<div>
<h1>Upload File</h1>
<form id="file-form" action="/Files/UploadFile" method="post" data-ajax="false" enctype="multipart/form-data">
<div><input type="file" id="FilePath" name="FilePath"/>
<button type="submit">Send File</button></div>
</form>
</div>
@section scripts{
<script src="~/Scripts/jquery-1.10.2.js"></script>
<script type="text/javascript">
// Variable to store your files
var files;
var form = document.getElementById('file-form');
// Add events
$('input[type=file]').on('change', prepareUpload);
// Grab the files and set them to our variable
function prepareUpload(event) {
files = $('#FilePath').get(0).files;
}
form.onsubmit = function (event) {
uploadFiles(event);
}
// Catch the form submit and upload the files
function uploadFiles(event) {
event.stopPropagation(); // Stop stuff happening
event.preventDefault(); // Totally stop stuff happening
// Create a formdata object and add the files
var data = new FormData();
if (files.lenght > 0)
{
data.append('UploadedFiles', files[0], file[0].name);
}
//setup request
var xhr = new XMLHttpRequest();
//open connection
xhr.open('POST', '/Files/UploadFile',false);
xhr.setRequestHeader("Content-Type", files.type);
//send request
xhr.send(data);
}
</script>
}
處理程序:
/// <summary>
/// Uploads the file.
/// </summary>
/// <returns></returns>
[HttpPost]
public virtual ActionResult UploadFile()
{
HttpPostedFile myFile = System.Web.HttpContext.Current.Request.Files["UploadedFiles"];
bool isUploaded = false;
string message = "File upload failed";
if (myFile != null && myFile.ContentLength != 0)
{
string pathForSaving = Server.MapPath("~/Uploads");
if (this.CreateFolderIfNeeded(pathForSaving))
{
try
{
myFile.SaveAs(Path.Combine(pathForSaving, myFile.FileName));
isUploaded = true;
message = "File uploaded successfully!";
}
catch (Exception ex)
{
message = string.Format("File upload failed: {0}", ex.Message);
}
}
}
return Json(new { isUploaded = isUploaded, message = message }, "text/html");
}

}

請幫助我。謝謝。
試過了,它仍然沒有工作。在我的表單頭部旁邊已經包含了代碼<... enctype =「multipart/form-data」>。 – BNguyen 2014-11-03 19:04:57
