将数组从JavaScript传递到C＃ [英] Pass an array from javascript to c#

问题描述

我在javascript中有一个数组，我需要将其保存到我的C＃webMethod中。最好的方法是什么？

I have a array in javascript and i need to get it to my c# webMethod. what is the best way to do this?

我的c＃代码是这样的：

my c# code is like this:

 [WebMethod]
public static void SaveView(string[]  myArray, string[] filter)
{
}

编辑-

我的json数据如下：

My json data looks like this:

{"myArray":[{"name":"Title","index":"Title","hidden":false,"id":"1","sortable":true,"searchoptions":{"sopt":["cn","eq","bw","ew"]},"width":419,"title":true,"widthOrg":150,"resizable":true,"label":"Title","search":true,"stype":"text"},{"name":"Author","index":"Author","hidden":false,"id":"3","sortable":true,"searchoptions":{"sopt":["cn","eq","bw","ew"]},"width":419,"title":true,"widthOrg":150,"resizable":true,"label":"Author","search":true,"stype":"text"}]}

但是我不起作用...不知道为什么吗？

But i doesnt work... any idea why?

非常感谢。

推荐答案

您可以将其作为JSON字符串发送。这是使用jQuery的示例：

You could send it as a JSON string. Here's an example using jQuery:

var array = [ 'foo', 'bar', 'baz' ];
$.ajax({
    url: '/foo.aspx/SaveView',
    type: 'POST',
    contentType: 'application/json',
    data: JSON.stringify({ myArray: array }),
    success: function(result) {

    }
});

如果Page方法返回某些内容，则应使用 result.d <成功回调中的/ code>属性以获取页面方法调用的结果。

If your Page Method returns something, you should use the result.d property in the success callback to fetch the result of the page method call.

如果您不使用jQuery，则必须手动进行帐户处理浏览器在发送AJAX请求方面的差异。但是，要使其正常工作，请求中必须包含2个关键内容：

If you don't use jQuery, you will have to manually account for browser differences in sending the AJAX request. But for this to work there are 2 crucial things to be included in the request:

• Content-Type请求标头必须设置为 application / json


• 请求有效负载应为JSON，例如： {myArray：['foo'， 'bar'，'baz']}

• The Content-Type request header must be set to application/json
• The request payload should be JSON, for example: { myArray: [ 'foo', 'bar', 'baz' ] }

更新：

现在您已经更新了问题，似乎您不再愿意发送字符串数组。因此，定义一个与您要发送的JSON结构匹配的模型：

Now that you have updated your question it seems that you are no longer willing to send an array of strings. So define a model that will match the JSON structure you are sending:

public class Model
{
    public string Name { get; set; }
    public string Index { get; set; }
    public bool Hidden { get; set; }
    public int Id { get; set; }
    public bool Sortable { get; set; }
    public SearchOption Searchoptions { get; set; }
    public int Width { get; set; }
    public bool Title { get; set; }
    public int WidthOrg { get; set; }
    public bool Resizable { get; set; }
    public string Label { get; set; }
    public bool Search { get; set; }
    public string Stype { get; set; }
}

public class SearchOption
{
    public string[] Sopt { get; set; }
}

然后：

[WebMethod]
public static void SaveView(Model[] myArray)
{
}
