我的 json 数据如下所示：

You could send it as a JSON string. Here's an example using jQuery:
您可以将其作为 JSON 字符串发送。下面是一个使用 jQuery 的例子：
var array = [ 'foo', 'bar', 'baz' ];
$.ajax({
url: '/foo.aspx/SaveView',
type: 'POST',
contentType: 'application/json',
data: JSON.stringify({ myArray: array }),
success: function(result) {
}
});
If your Page Method returns something, you should use the result.dproperty in the success callback to fetch the result of the page method call.
如果你的页面方法返回了一些东西，你应该使用result.d成功回调中的属性来获取页面方法调用的结果。
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:
如果您不使用 jQuery，则必须手动考虑浏览器在发送 AJAX 请求时的差异。但是要使其正常工作，请求中需要包含两件重要的事情：
- The Content-Type request header must be set to
application/json - The request payload should be JSON, for example:
{ myArray: [ 'foo', 'bar', 'baz' ] }
- Content-Type 请求头必须设置为
application/json - 请求负载应该是 JSON，例如：
{ myArray: [ 'foo', 'bar', 'baz' ] }
UPDATE:
更新：
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:
现在您已经更新了您的问题，您似乎不再愿意发送字符串数组。因此，定义一个与您发送的 JSON 结构相匹配的模型：
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; }
}
and then:
进而：
[WebMethod]
public static void SaveView(Model[] myArray)
{
}

var xhr = new XMLHttpRequest();
xhr.open("POST", "mypage/SaveView");
xhr.setRequestHeader("Content-Type", "application/json");
xhr.send(JSON.stringify({ myArray: someArray }));
