试图将对象强制转换为JavaScript的[] {} - C＃核心价值集合或字典＆LT;字符串，对象＆gt;或LT;字符串，字符串＆GT;

问题描述

我想更好地了解铸造对象的名称VS收藏价值的问题

i'd like to better understand the issue of casting object to a name vs value collection

说......只是如果我能做到这一点像

say ...just if i could do it like that

1）没有Java的脚本需要一些微调？打包的数据。

1) does the java-script needs some fine tuning ? packing the data..

2）对我来说最重要的是：什么是做从该键值的js 转换为<$ C的正确方法$ C>词典＆LT; T，T＆GT; C＃？

2) and most important for me : What is the correct way to do the conversion from that key value Js to a Dictionary<T,T> C# ?

在在.aspx / HTML 部分。

<input type="text" id="tbx_Name" value="Avi" />
<input type="text" id="tbx_City" value="TelAviv" />
<input type="text" id="tbx_Country" value="Israel" />

<select id="ChosenRandomClass" style="display:none">
<option selected="selected" value="0">(choose a random)</option>
<option value="1">random Top Beach</option>
<option value="2">random Top Center</option>
<option value="3">random Local Pub</option>
</select>

在的JavaScript / jQuery的部分。

  function AddNew() {

        if (!confirm("would you like to add this contact ?")) return;

        var Name = $('#tbx_Name').val();
        var City = $('#tbx_City').val();
        var Country = $('#tbx_Country').val();

        var selectedRC = $('#ChosenRandomClass option:selected').val();

        var hDate = []

        var param1 = { key: "Name", value: Name };
        var param2 = { key: "City", value: City };
        var param3 = { key: "Country", value: Country };
        var param4 = { key: "SelctedClass", value: selectedRC };

        hDate.push(param1);
        hDate.push(param2);
        hDate.push(param3);
        hDate.push(param4);
                                         // is this part necessary the data will not get to
                                         // code behind properly without the serializing ?
        var startPrt = Sys.Serialization.JavaScriptSerializer.serialize(hDate);
              ajaxUpdate("addNew", startPrt);

    }

在 code后面的C＃部分。

public void AddNewRecord(object startPrt)
{
    Dictionary<string, string> SenthDate = new Dictionary<string, string>();
   //        .....etc

}

我会的AP preciate正确的答案

i will appreciate the correct answer

感谢你的帮助和时间。

推荐答案

我给你的样品一试，发现在 startPrt 参数实际上是被接收为阵列中的词典（字符串对象）。因此，如果您的AJAX调用是这样的：

I gave your sample a try and noticed that the startPrt parameter is actually being received as an Array of Dictionary(string, object). Hence, if you make the AJAX call like this:

var hDate = [];
hDate.push({ key: "Name", value: Name });
hDate.push({ key: "City", value: City });
hDate.push({ key: "Country", value: Country });
hDate.push({ key: "SelctedClass", value: selectedRC });

$.ajax({
    contentType: 'application/json; charset=utf-8',
    url: 'MyPage.aspx/AddNewRecord',
    type: 'POST',
    data: JSON.stringify({ startPrt: hDate }),
    success: success, // success callback
    error: error // error callback
});

您可以定义您的的WebMethod 像follwoing转换的 startPrt 参数字典：

You can define your WebMethod like the follwoing to convert the startPrt parameter to a dictionary:

[WebMethod]
public static void AddNewRecord(object startPrt)
{
    var dict = new Dictionary<string, object>();
    foreach (Dictionary<string, object> pair in (Array)startPrt)
        dict.Add((string)pair["key"], pair["value"]);
}
