我试图在Windows窗体中使用JSON.NET框架从JSON字符串中读取一些信息。但是我努力获得来自“taxonomies->主题”阵列的字典和“集群”JSON.NET到C＃对象
{
"keywords": {
"anyString": [
],
"allString": {
"a5349f533e3aa3ccbc27de2638da38d6": "olympics"
},
"exactString": [
],
"notString": [
],
"highlightString": [
]
},
"dates": {
"startDate": "15-01-2008",
"endDate": "15-09-2009",
"useDates": true
},
"clusters": {
"permission": {
"1": "private\/n"
}
},
"taxonomies": {
"Topics": {
"2488": "Olympics 2012 (not participation)",
"8876": "Olympics and culture"
},
"Keywords": {
"8848": "Engineering in the Olympics"
}
},
"sort": {
"sortId": 1,
"sortType": 2,
"sort": "datetime",
"sortOrder": "descending"
}
}
随着代码波纹管，我已经能够阅读一些资料。
JObject searchCriteria = JObject.Parse(contentSearchCriteria);
//search criteria
IEnumerable<string> allString = searchCriteria["keywords"]["allString"].Children().Values<string>();
IEnumerable<string> anyString = searchCriteria["keywords"]["anyString"].Children().Values<string>();
IEnumerable<string> notString = searchCriteria["keywords"]["notString"].Children().Values<string>();
IEnumerable<string> exactString = searchCriteria["keywords"]["exactString"].Children().Values<string>();
IEnumerable<string> highlightString = searchCriteria["keywords"]["highlightString"].Children().Values<string>();
//dates
string startDate = (string)searchCriteria["dates"]["startDate"];
string endDate = (string)searchCriteria["dates"]["endDate"];
bool useDates = (bool)searchCriteria["dates"]["useDates"];
//sort
int sortId = (int)searchCriteria["sort"]["sortId"];
int sortType = (int)searchCriteria["sort"]["sortType"];
string sort = (string)searchCriteria["sort"]["sort"];
string sortOrder = (string)searchCriteria["sort"]["sortOrder"];
UPDATE：
至于建议我加入
class SMSearchCriteria
{
public SMKeywords keywords { get; set; }
public SMDates dates { get; set; }
public SMClusters clusters { get; set; }
public SMTaxonomies taxonomies { get; set; }
public SMSort sort { get; set; }
}
class SMKeywords
{
public List<Dictionary<string, string>> AnyString {get; set;}
public List<Dictionary<string, string>> AllString { get; set; }
public List<Dictionary<string, string>> ExactString { get; set; }
public List<Dictionary<string, string>> NotString { get; set; }
public List<Dictionary<string, string>> HighlightString { get; set; }
}
class SMDates
{
public string startDate { get; set; }
public string endDate { get; set; }
public bool useDates { get; set; }
}
class SMClusters
{
List<SMCluster> cluster;
}
class SMCluster
{
public Dictionary<string, string> cluster { get; set; }
}
class SMTaxonomies
{
public List<SMTaxonomy> taxonomies { get; set; }
}
class SMTaxonomy
{
public Dictionary<string, List<SMCategory>> taxonomy { get; set; }
}
class SMCategory
{
public Dictionary<int, string> category { get; set; }
}
class SMSort
{
public int sortId { get; set; }
public int sortType { get; set; }
public string sort { get; set; }
public string sortOrder { get; set; }
}
但是当我执行：
var mydata = JsonConvert.DeserializeObject<SMSearchCriteria>(contentSearchCriteria);
我得到异常：
[Newtonsoft.Json.JsonSerializationException] = {"Cannot deserialize JSON object into type 'System.Collections.Generic.List`1[System.Collections.Generic.Dictionary`2[System.String,System.String]]'."}
更新2：
至于建议我已删除了所有额外的清单，简化了类此：
class SearchMasterSearchCriteria
{
public SMKeywords keywords { get; set; }
public SMDates dates { get; set; }
public Dictionary<string, Dictionary<int, string>> clusters { get; set; }
public Dictionary<string, Dictionary<int, string>> taxonomies { get; set; }
public SMSort sort { get; set; }
}
class SMKeywords
{
public Dictionary<string, string> anyString {get; set;}
public Dictionary<string, string> allString { get; set; }
public Dictionary<string, string> exactString { get; set; }
public Dictionary<string, string> notString { get; set; }
public Dictionary<string, string> highlightString { get; set; }
}
class SMDates
{
public string startDate { get; set; }
public string endDate { get; set; }
public bool useDates { get; set; }
}
class SMSort
{
public int sortId { get; set; }
public int sortType { get; set; }
public string sort { get; set; }
public string sortOrder { get; set; }
}
我还添加了测试代码序列化对象是这样的：
//criteria
SearchMasterSearchCriteria smCriteria = new SearchMasterSearchCriteria();
//keywords
SMKeywords smKeywords = new SMKeywords(); ;
Dictionary<string, string> dict = new Dictionary<string, string>();
dict.Add("a5349f533e3aa3ccbc27de2638da38d6", "olympics");
dict.Add("9cfa7aefcc61936b70aaec6729329eda", "games");
smKeywords.allString = dict;
//category
Dictionary<int, string> categorieDict = new Dictionary<int, string>();
categorieDict.Add(2488, "Olympics 2012 (not participation)");
categorieDict.Add(8876, "Olympics and culture");
//taxonomies
Dictionary<string, Dictionary<int, string>> taxonomiesDict = new Dictionary<string, Dictionary<int, string>>();
taxonomiesDict.Add("Topics", categorieDict);
//metadata
Dictionary<int, string> metadataDict = new Dictionary<int, string>();
metadataDict.Add(1, @"private/n");
//clusters
Dictionary<string, Dictionary<int, string>> clustersDict = new Dictionary<string, Dictionary<int, string>>();
clustersDict.Add("permission", metadataDict);
//dates
SMDates smDates = new SMDates();
smDates.startDate = "15-01-2008";
smDates.endDate = "15-09-2009";
smDates.useDates = true;
//sort
SMSort smSort = new SMSort();
smSort.sortId = 1;
smSort.sortType = 2;
smSort.sort = "datetime";
smSort.sortOrder = "descending";
//add to criteria.
smCriteria.keywords = smKeywords;
smCriteria.clusters = clustersDict;
smCriteria.taxonomies = taxonomiesDict;
smCriteria.dates = smDates;
smCriteria.sort = smSort;
//serialize
string json = JsonConvert.SerializeObject(smCriteria);
var mydata1 = JsonConvert.DeserializeObject<SearchMasterSearchCriteria>(json);
那时候2个json字符串之间的唯一区别在哪里。 []和对anyString，exactString等空值，因此我更换了空方括号卷发的人，并没有错误:)
contentSearchCriteria = contentSearchCriteria.Replace("[]", "{}");
var mydata = JsonConvert.DeserializeObject<SearchMasterSearchCriteria>(contentSearchCriteria);
蒂莫西嗨，你建议我已经更新了类的问题。但我得到一个例外。 –
