WCF/C＃上傳文件

我目前正在使用C＃和WCF的Web服務。我需要做一個上傳方法，所以我遵循this tutorial。現在我可以通過表單上傳文件和文件上傳的文件夾中，但在瀏覽器中它總是返回我有一個錯誤（像在阿賈克斯指定）這裏的所有代碼：WCF/C＃上傳文件

IWebService.cs

[ServiceContract] 
public interface IWebService 
{ 
    [OperationContract] 
    [WebInvoke(Method = "POST", UriTemplate = "/UploadFile?fileName={fileName}")] 
    void UploadFile(string fileName, Stream stream); 
}

WebService.svc

public void UploadFile(string fileName, Stream stream) 
{ 
    string FilePath = Path.Combine(HostingEnvironment.MapPath("~/FileServer/Uploads"), fileName); 

    int length = 0; 
    using (FileStream writer = new FileStream(FilePath, FileMode.Create)) 
    { 
     int readCount; 
     var buffer = new byte[8192]; 
     while ((readCount = stream.Read(buffer, 0, buffer.Length)) != 0) 
     { 
      writer.Write(buffer, 0, readCount); 
      length += readCount; 
     } 
    } 
}

TestClient.html

<head> 
<script type="text/javascript"> 
    function UploadFile() { 
     fileData = document.getElementById("fileUpload").files[0]; 
     var data = new FormData(); 

     $.ajax({ 
      url: 'http://localhost:1945/Service1.svc/UploadFile?fileName=' + fileData.name, 
      type: 'POST', 
      data: fileData, 
      cache: false, 
      dataType: 'json', 
      processData: false, // Don't process the files 
      contentType: "application/octet-stream", // Set content type to false as jQuery will tell the server its a query string request 
      success: function (data) { 
       alert('successful..'); 
      }, 
      error: function (data) { 
       alert('Some error Occurred!'); 
      } 
     }); 
    } 

</script> 
<title></title> 
</head> 
<body> 
<div> 
    <div> 
     <input type="file" id="fileUpload" value="" /> 
     <br /> 
     <br /> 
     <button id="btnUpload" onclick="UploadFile()"> 
      Upload 
     </button> 
    </div> 
</div> 
</body>

我在試圖解決我的路

更改retun型UploadCustomFile方法字符串的問題所在，並返回一個假消息

公共字符串UploadCustomFile（字符串文件名，System.IO.Stream流） { string FilePath = Path.Combine（HostingEnvironment.MapPath（「〜/ FileServer/Uploads」），fileName）;加入

int length = 0; 
using (FileStream writer = new FileStream(FilePath, FileMode.Create)) 
{ 
    int readCount; 
    var buffer = new byte[8192]; 
    while ((readCount = stream.Read(buffer, 0, buffer.Length)) != 0) 
    { 
     writer.Write(buffer, 0, readCount); 
     length += readCount; 
    } 
} 

    try 
    { 
     //do something else 
    } 
    catch 
    {  
      //to return custom error message - ajax will catch this as a error 
      HttpContext.Current.Response.Write(""); 
      return "not okey"; 
    } 

return "okey"; 
}

更改接口方法ResponseFormat = WebMessageFormat.Json和字符串返回類型

[OperationContract] 
[WebInvoke(ResponseFormat = WebMessageFormat.Json, Method = "POST", UriTemplate = "/UploadFile?fileName={fileName}")] 
String UploadCustomFile(string fileName, Stream stream);

當我試圖這樣，我得到了成功警報消息
