Silverlight-> JS-> MVC [英] Silverlight -> JS -> MVC

问题描述

嗨！

我有一个基于MVC的Web门户，并在其中一个页面上嵌入了Silverlight应用程序.

SL应用程序生成文件，应通过调用MVC操作将其发送到服务器.

我尝试过的....
SL应用中的代码:

Hi!

I have a web portal, that is based on MVC and has embedded Silverlight app on one of it''s page.

SL application generate file, that should be sent to server by calling MVC action.

What I have tried....
Code in SL app:

HtmlPage.Window.Invoke("SendNewImage", new object[] { bitmap.PixelWidth, bitmap.PixelHeight, stream.ToArray()});

JS中的SendNewImage函数:

SendNewImage function in JS:

function SendNewImage(width, height, pixels) {
    $.post("/Files/UploadImage", { 'pixels[]': pixels },
    function (success) {
    },"json"
  );

MVC动作:

MVC action:

[AcceptVerbs(HttpVerbs.Post)]
public JsonResult UploadImage(byte[] pixels)
{

    return Json(new object[] {});
}

问题...
当我将byte []作为Invoke()的参数发送给JS时，我没有在javascript函数中获取Array.相反，我有对象"像素，在萤火虫中看起来不像Array，但是我可以通过调用pixel [10]来获取值.

然后，当我在MVC动作中接收数据时，则为NULL.我不知道问题出在哪里...在senind到JS或调用MVC动作时.有人知道吗?

谢谢

Problems...
When I send byte[] to JS as a parameter of Invoke(), I dont get Array inside javascript function. Instead I have ''object'' pixels, that is not looking as Array in firebug, but I can get values by calling pixels[10], for example.

Then, when I recieve data in MVC action, then is NULL. I dont where is the problem...while senind to JS, or while calling MVC action. Anybody knows?

Thanks

推荐答案

.post(" ，{ pixels []':像素}， 功能(成功){ }，" );

.post("/Files/UploadImage", { 'pixels[]': pixels }, function (success) { },"json" );

MVC动作:

MVC action:

[AcceptVerbs(HttpVerbs.Post)]
public JsonResult UploadImage(byte[] pixels)
{

    return Json(new object[] {});
}
