这里记录一个 Newtonsoft.Json 的扩展,可以将 JObject 直接转换为字典类型 Dictionary<string, object>
使用方法为
Dictionary<string, object> json = JsonConvert.DeserializeObject<JToken>(content).ToDictionary();
或者
Dictionary<string, object> json = JToken.Parse(content).ToDictionary();
详细代码如下
/// <summary>
/// JObject扩展
/// </summary>
public static class JObjectExtensions
{
/// <summary>
/// 将JObject转化成字典
/// </summary>
/// <param name="json"></param>
/// <returns></returns>
public static Dictionary<string, object> ToDictionary(this JToken json)
{
var propertyValuePairs = json.ToObject<Dictionary<string, object>>();
ProcessJObjectProperties(propertyValuePairs);
ProcessJArrayProperties(propertyValuePairs);
return propertyValuePairs;
}
private static void ProcessJObjectProperties(Dictionary<string, object> propertyValuePairs)
{
var objectPropertyNames = (from property in propertyValuePairs
let propertyName = property.Key
let value = property.Value
where value is JObject
select propertyName).ToList();
objectPropertyNames.ForEach(propertyName => propertyValuePairs[propertyName] = ToDictionary((JObject)propertyValuePairs[propertyName]));
}
private static void ProcessJArrayProperties(Dictionary<string, object> propertyValuePairs)
{
var arrayPropertyNames = (from property in propertyValuePairs
let propertyName = property.Key
let value = property.Value
where value is JArray
select propertyName).ToList();
arrayPropertyNames.ForEach(propertyName => propertyValuePairs[propertyName] = ToArray((JArray)propertyValuePairs[propertyName]));
}

public static ArrayList ToArray(this JArray array)
{
object[] list = array.ToObject<object[]>().Select(ProcessArrayEntry).ToArray();
return new ArrayList(list);
}
private static object ProcessArrayEntry(object value)
{
if (value is JObject)
{
return ToDictionary((JObject)value);
}
if (value is JArray)
{
return ToArray((JArray)value);
}
return value;
}
}
