to：lonely7345 孤独侠客
List<dealertest> thislist = new List<dealertest>();
object o=Newtonsoft.Json.JavaScriptConvert.DeserializeObject(returnstr);
Newtonsoft.Json.JavaScriptArray dls = o as JavaScriptArray;

这个时候dls已经是null了，为什么转不成呢？

不要把它带的例子误导,看看下面我专门给你写的吧.测试通过:

public class dealertest 
{   
    public long identity 
    { 
        get;
		set;
  } 
    public int siteId 
    { 
        get ;
		set;
    } 
}

//序列化		
List<dealertest> list = new List<dealertest>();
dealertest  d = new  dealertest();
d.identity=323;
d.siteId = 32;
list.Add(d);
Console.Write(JavaScriptConvert.SerializeObject(list));
		
//反序列化
string returnstr = @"[{""identity"":1047744,""siteId"":10 },{""identity"":1047745,""siteId"":11}]"; 
List<dealertest> thislist = new List<dealertest>(); 
thislist =JavaScriptConvert.DeserializeObject<List<dealertest>>(returnstr);
Console.Write(thislist.Count);

没具体做过 看看这些 json的api对你有帮助不

o = Newtonsoft.Json.JavaScriptConvert.DeserializeObject(returnstr);
Newtonsoft.Json.JavaScriptArray  dls= o as Newtonsoft.Json.JavaScriptArray;
for (int i = 0; i < dls.Count; i++)
{
      thislist.Add(new dealertest(dls[i]));
      //这里你可以有一个转换方式,就是json实体和你的实体的转换.
     //或者是你看一下,直接把o转换成你的List类型可以不可以
}

好东西，要顶顶顶，受教了

[生财]

好.贴.要顶

lonely7345 说的就是这样的

public class dealertest 
{   
    public long identity 
    { 
        get;
        set;
  } 
    public int siteId 
    { 
        get ;
        set;
    } 
}

//序列化        
List<dealertest> list = new List<dealertest>();
dealertest  d = new  dealertest();
d.identity=323;
d.siteId = 32;
list.Add(d);
Console.Write(JavaScriptConvert.SerializeObject(list));
        
//反序列化
string returnstr = @"[{""identity"":1047744,""siteId"":10 },{""identity"":1047745,""siteId"":11}]"; 
List<dealertest> thislist = new List<dealertest>(); 
thislist =JavaScriptConvert.DeserializeObject<List<dealertest>>(returnstr);
Console.Write(thislist.Count);

.NET 2.0不支持json格式，真哎。。。
