在WCF(json)中构建响应时,我很确定不可能使用完全动态的对象,但只是想先在这里仔细检查。
理想的回答看起来像:
"userTypes" :
{
"BartSimpson" :
{
"url" : "foo",
"desc" : "bar"
},
"LisaSimpson" :
{
"url" : "foo",
"desc" : "bar"
}
}
在“编译”代码中,上述内容可以通过以下架构(稍微伪代码)执行:
public class Character{
string url {get;set;}
string desc{get;set;}
}
public class UserTypes{
public Character BartSimpson{get;set;}
public Character LisaSimpson{get;set;}
}
但我的主要目标是BartSimpson
和LisaSimpson
不会被“编译”,所以我可以拥有任意数量的Character
类,任何名称/在回应中确定。

在服务实现类的顶部添加以下using
(确保您还在项目中添加了正确的引用):
using Newtonsoft.Json;
using System.Dynamic;
using System.IO;
using System.Text;
您可以尝试这种输出动态结果的简单方法:
public string GetData()
{
dynamic d = new ExpandoObject();
dynamic bartSimpson = new ExpandoObject();
dynamic lisaSimpson = new ExpandoObject();
bartSimpson.url = "foo";
bartSimpson.desc = "bar";
lisaSimpson.url = "foo";
lisaSimpson.desc = "bar";
d.userTypes = new ExpandoObject();
d.userTypes.BartSimpson = bartSimpson;
d.userTypes.LisaSimpson = lisaSimpson;
var s = JsonSerializer.Create();
var sb = new StringBuilder();
using (var sw = new StringWriter(sb))
{
s.Serialize(sw, d);
}
return sb.ToString();
}
再往前走一步(你只需要在comaSeparatedNames
值中传递Bart和Lisa),你可以这样做:
public string GetData(string comaSeparatedNames)
{
string[] names = comaSeparatedNames.Split(',');
dynamic d = new ExpandoObject();
dynamic dNames = new ExpandoObject();
foreach (var name in names)
{
dynamic properties = new ExpandoObject();
properties.url = "foo";
properties.desc = "bar";
((IDictionary<string, object>)dNames).Add(name, properties);
}
((IDictionary<string, object>)d).Add("userTypes", dNames);
var s = JsonSerializer.Create();
var sb = new StringBuilder();
using (var sw = new StringWriter(sb))
{
s.Serialize(sw, d);
}
// deserializing sample
//dynamic dummy = new ExpandoObject();
//var instance = s.Deserialize(new StringReader(sb.ToString()),
// dummy.GetType());
//var foo = instance.userTypes.BartSimpson.url;
return sb.ToString();
}
注意:我还提供了用于反序列化的行(注释)。
