Asp.net Mvc Controller接收可控的数组或字典类型的实现方法：
方法一，（最复杂的方法）
扩展ModelBinder 完全自定义一种参数的解析方法。
/// <summary>
/// 模式绑定数组接收器 eg:，接收字符数组：参数标记如 [ModelBinder(typeof(ArrayBind<string>))]string[] arrayValue
/// </summary>
/// <typeparam name="T"></typeparam>
public class ArrayBind<T> : IModelBinder
{
private _T GetValue<_T>(ModelBindingContext bindingContext, string key)
{
ValueProviderResult valueResult = bindingContext.ValueProvider.GetValue(key);
bindingContext.ModelState.SetModelValue(key, valueResult);
return (_T)valueResult.ConvertTo(typeof(_T));
}
#region IModelBinder 成员
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
Dictionary<int, T> list = new Dictionary<int, T>();
string[] allKey = controllerContext.HttpContext.Request.Form.AllKeys;
foreach (string key in allKey)
{
if (!key.StartsWith(bindingContext.ModelName, StringComparison.CurrentCultureIgnoreCase))
{
continue;
}
string[] _key = key.Split('.');
if (_key.Length != 2)
{
continue;
}
int me = 0;
if (int.TryParse(_key[1], out me))
{
list.Add(me, GetValue<T>(bindingContext, key));
}
}
var sort = from k in list orderby k.Key ascending select k;
return sort.Select<KeyValuePair<int, T>, T>(C => C.Value).ToArray();
}
#endregion
}
然后在Controller的action方法参数中进行标记，如：
[HttpPost]
public ActionResult Edit([Bind(Prefix = "LevelDescription")][ModelBinder(typeof(ArrayBind<string>))]string[] levelOrder)
{
return Json(1);
}
方法二，url参数解析法
http://www.domain.com/post?levelOrder=1&levelOrder=2&levelOrder=3&levelOrder=4&levelOrder=5
方法三，
Js异步提交数据，
var _lev = {};
_lev["lev[0].Status"] = "5"; //这里必须从零开始 名字必须一样
_lev["lev[1].Status"] = "6";
$.post("Edit", _lev
, function(json) {
if (json == "1") { alert(''成功)}
}, "json");
action方法，如：
[HttpPost]
public ActionResult Edit(Level[] lev)
{
return Json(lev);
}
如果在action中欲接收一Dictionary 类型值，则变得更加方便，
$("tr[name = 'LeelArea']").each(function(index) {
_lev["levelOrder1[" + index + "].key"] = index; //这里必须从零开始 名字必须一样
_lev["levelOrder1[" + index + "].value"] = $(this).find("textarea").val();
});
if ($(this).valid()) {
$.post("Edit", _lev
, function(json) {
Alert(json);
}, "json");
}
action方法，如：
[HttpPost]
public ActionResult Edit(Dictionary<int,string> levelOrder)
{
return Json(1);
}
参考老外的：
http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx
//js
//List<User>
var _lev = {};
_lev["user[0].name"] = "wudi";
_lev["user[0].pwd"] = "pwd";
_lev["user[1].name"] = "wudi";
_lev["user[1].pwd"] = "pwd";
$.post("/home/Add", _lev, function(result) {
if (result <= 0) {
alert('保存记录失败！');
}
else {
c_pr_c.ID = result;
}
}, "json");
//Dictionary<string,user>
var _lev = {};
_lev["stock[0].key"] = "MSFT"
_lev["stock[0].value"] = "Microsoft Corporation"
_lev["stock[1].key"]= "AAPL"
_lev["stock[1].value"] = "Apple, Inc."
$.post("/home/AddDic", _lev, function(result) {
if (result <= 0) {
alert('保存记录失败！');
}
else {
c_pr_c.ID = result;
}
}, "json");
public class user
{
public string name { get; set; }
public string pwd { get; set; }
}
public ActionResult Add(List<user> user)
{
return View();
}
public ActionResult AddDic(IDictionary<string, string> stock)
{
return View();
}
