发送一个jQuery数组回一个C＃字符串数组 [英] Sending a jQuery array back to a c# String Array

问题描述

我有一个需要的String [] 阵列的C＃方法，我用 $。的getJSON 来电传递参数的控制方法。

I have a C# method that requires a String[] array and I use a $.getJSON call to deliver the parameters to the Method in the Controller.

我正在已选定的复选框的值，并通过他们回到控制器，但是当我使用字符串化它的地方，如果多个值，在一起，当我通过阵列自身，也有多个条目，但接收的String [] 为空。

I am taking the values of Checkboxes that have been selected and passing them back to the Controller, however when I use Stringify it places if multiple values, together and when I pass the array its self, there are multiple entries, however the receiving String[] is null.

var array = new Array();
$('#ids:checked').each(function() {
    array.push($(this).val())
}

var jsonText = JSON.stringify(array); // I have tried this, but to receive one entry
var dataValues = { 
    ids: jsonText, 
    id: $('#idNumber').val(), 
    orderId: $('#orderId').val()
};

$.getJSON("/path/to/method", dataValues, function(){});

public ActionResult doSomething(String[] ids, Int32 Id, Int32 OrderId)
{
    //do something here
}

感谢您的帮助。

推荐答案

您正在设置 IDS 的值JSON字符串;但是，服务器无法知道的方式。至于服务器知道， IDS 是字符串价值，不能被转换为的String [] 。

You are setting the value of ids to a JSON string; however, the server has no way of knowing that. As far as the server knows, ids is a string value, which can't be converted to string[].

而不是一个值转换为JSON的，应在整个数据对象转换为JSON并指定其内容类型：

Instead of converting one value to JSON, you should convert the whole data object to JSON and specify its content-type:

var dataValues = { 
    ids: array, //the Javascript array, *not* the JSON string
    id: $('#idNumber').val(), 
    orderId: $('#orderId').val()
};

$.ajax({
    url: "/path/to/method", 
    data: JSON.stringify(dataValues),
    success: function(){},
    contentType: "application/json"
});
