.Net mvc 根据前台参数动态绑定对象

业务需求：根据前台界面的参数，动态绑定对象

<param name="colNames">属性名拼接字符串</param>
<param name="data">数据json字符串（前台数组形式）</param>

public ActionResult BindObject(string colNames,string data)
{

var jsonData = JsonConvert.DeserializeObject<dynamic>(data);
if (colNames == null)
{
return RedirectToAction("Index", new { area = "Assessment" });
}
string[] colNamesArray = colNames.Split(',');

List<ExpandoObject> list = new List<ExpandoObject>();

foreach (var item in jsonData)
{
dynamic expandoObject = new ExpandoObject();
foreach (var colName in colNamesArray)
{
(expandoObject as ICollection<KeyValuePair<string, object>>).Add(new KeyValuePair<string, object>(colName, item[colName]));
}
list.Add(expandoObject);
}

return View();

前台js代码：

//收集列头(属性名)数据
var array = new Array();
var table = $('#tb-data')[0];
for (var i = 0; i < 1; i++) {
for (var j = 0; j < table.rows[0].cells.length; j++) {
var colName = table.rows[0].cells[j].innerText;
array.push(colName);
}
}
//收集数据
var dataArray = new Array();
for (var i = 1; i < table.rows.length; i++) {
var value = {};
for (var j = 0; j < table.rows[i].cells.length; j++) {
if (table.rows[i].cells[j].innerText == undefined || table.rows[i].cells[j].innerText == "") {
value[array[j]] = "";
} else {
value[array[j]] = table.rows[i].cells[j].innerText;
}
}
dataArray.push(value);
}

var postUrl = '/Accounting/AllEvaluate/Export';//提交地址
var postData = JSON.stringify(dataArray);//第一个数据
var ExportForm = document.createElement("FORM");
document.body.appendChild(ExportForm);
ExportForm.method = "POST";
var newElement = document.createElement("input");
newElement.setAttribute("name", "data");
newElement.setAttribute("type", "hidden");
ExportForm.appendChild(newElement);
var newElement2 = document.createElement("input");
newElement2.setAttribute("name", "colNames");
newElement2.setAttribute("type", "hidden");
ExportForm.appendChild(newElement2);
newElement2.value = array;
newElement.value = postData;
ExportForm.action = postUrl;
ExportForm.submit();
