我的网络服务接收 JSON 格式的数据过滤值。以下是如何发送过滤条件的示例:

var jsonString = { 
"startDate":"2015-01-19T15:04:54.897Z", 
"endDate":"2016-01-19T15:04:54.897Z", 
"filterParams":{ 
    "facilityIds": 
        [ 
            {"ID":1,"charID":"1","Description":"Health Group Umbrella Organization","DoubleValue1":35.009803,"DoubleValue2":85.21,"StringValue1":""}, 
            {"ID":2,"charID":"2","Description":"Main Hospital Organization","DoubleValue1":35.04,"DoubleValue2":89.3,"StringValue1":""}, 
            {"ID":3,"charID":"3","Description":"Regional Medical Center","DoubleValue1":35.04,"DoubleValue2":89.30,"StringValue1":""} 
        ],                       
    "GenderIds":[{"ID":0,"charID":"F","Description":"Female","DoubleValue1":0,"DoubleValue2":0,"StringValue1":""}], 
    "AgeRangeIds":[{"ID":4,"charID":"4","Description":"30 - 34","DoubleValue1":0,"DoubleValue2":0,"StringValue1":""}], 
    "HomeownerIds":[{"ID":7,"charID":"7","Description":"More Likely Owner 1","DoubleValue1":0,"DoubleValue2":0,"StringValue1":""}], 
    "IncomeRangeIds":[{"ID":3,"charID":"3","Description":"$30,001 - $40,000","DoubleValue1":0,"DoubleValue2":0,"StringValue1":""}], 
    "HasChildrenIds":[{"ID":0,"charID":"N","Description":"No","DoubleValue1":0,"DoubleValue2":0,"StringValue1":null}], 
    "EncoutnerTypesIds": 
        [ 
            {"ID":2,"charID":"2","Description":"Ambulatory","DoubleValue1":0,"DoubleValue2":0,"StringValue1":""}, 
            {"ID":1,"charID":"1","Description":"InPatient","DoubleValue1":0,"DoubleValue2":0,"StringValue1":""}, 
            {"ID":3,"charID":"3","Description":"Emergency","DoubleValue1":0,"DoubleValue2":0,"StringValue1":""}, 
            {"ID":4,"charID":"4","Description":"Office Visit","DoubleValue1":0,"DoubleValue2":0,"StringValue1":""} 
        ] 
    } 
} 

我可以毫无问题地取出 startDate 和 endDate:

var jsonValues = jsonSerializer.Deserialize<Dictionary<string, object>>(jsonString);             
DateTime startDate = DateTime.Parse(jsonValues["startDate"] as string); 
DateTime endDate = DateTime.Parse(jsonValues["endDate"] as string); 

但是，我似乎无法弄清楚如何处理 JSON 的“filterParams”部分。它应该映射到类结构:

public class FilterModel 
{ 
    public int ID { get; set; } 
    public char charID { get; set; } 
    public string Description { get; set; } 
    public double DoubleValue1 { get; set; } 
    public double DoubleValue2 { get; set; } 
    public string StringValue1 { get; set; } 
} 

以下语句使用正确的数据填充变量，但我无法访问这些值。

var filterParams = jsonValues["filterParams"]; 

我需要以某种方式将数据反序列化为 Dictionary<string, FilterModel>但是 Deserialize 方法需要一个字符串参数，而 filterParams 是一个对象。

请您参考如下方法:

您不需要手动反序列化每个属性...

JavaScriptSerializer

您可以使用 native JavaScriptSerializer 将其直接反序列化为复杂对象:

RootObject obj = new JavaScriptSerializer().Deserialize<RootObject>(jsonString); 

Newtonsoft JSON

或者按照@Wobbles 的建议，您可以使用Json.Net 也称为Newtonsoft Json :

RootObject obj = JsonConvert.DeserializeObject<RootObject>(jsonString); 

如您所见here，它比 JavaScriptSerializer 速度更快且功能更多.
