C#-具有数字键的动态json对象
作者:互联网
我有一个json对象,我借助this答案将其转换为动态C#对象.它工作正常,但麻烦的是该对象具有数字键.例如,
var jsStr = "{address:{"100": {...}}}";
所以我不会想
dynObj.address.100
而且,据我所知,我不能使用索引器来获取此对象
dynObj.address["100"]
请向我解释如何使它正常工作.
解决方法:
据我在源代码中所见,他通过私有字典解析属性,因此您必须使用反射来访问字典键,或稍作修改,以使DynamicJSONObject中的TryGetMember如下(并使用__numeric__来获取密钥,例如data.address .__ numeric__100,然后避免使用__numeric__作为密钥):
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
var name = binder.Name;
//Code to check if key is of form __numeric__<number> so that numeric keys can be accessed
if (binder != null && binder.Name != null && binder.Name.StartsWith("__numeric__"))
{
name = binder.Name.Substring(11);
}
if (!_dictionary.TryGetValue(name, out result))
{
// return null to avoid exception. caller can check for null this way...
result = null;
return true;
}
var dictionary = result as IDictionary<string, object>;
if (dictionary != null)
{
result = new DynamicJsonObject(dictionary);
return true;
}
var arrayList = result as ArrayList;
if (arrayList != null && arrayList.Count > 0)
{
if (arrayList[0] is IDictionary<string, object>)
result = new List<object>(arrayList.Cast<IDictionary<string, object>>().Select(x => new DynamicJsonObject(x)));
else
result = new List<object>(arrayList.Cast<object>());
}
return true;
}
