使用Newtonsoft JsonConvert反序列化Json数据到DataTable

 1 //JsonStr为Json字符串
 2  JArray array = JsonConvert.DeserializeObject(JsonStr) as JArray;//反序列化为数组
 3 if (array.Count > 0)
 4             {
 5                 StringBuilder columns = new StringBuilder();
 6                 DataTable table = new DataTable();
 7                 JObject objColumns = array[0] as JObject;
 8                 //构造表头
 9                 foreach (JToken jkon in objColumns.AsEnumerable<JToken>())
10                 {
11                     string name = ((JProperty)(jkon)).Name;
12                     columns.Append(name + ",");
13                     table.Columns.Add(name);
14                 }
15                 //向表中添加数据
16                 for (int i = 0; i < array.Count; i++)
17                 {
18                     DataRow row = table.NewRow();
19                     JObject obj = array[i] as JObject;
20                     foreach (JToken jkon in obj.AsEnumerable<JToken>())
21                     {
22 
23                         string name = ((JProperty)(jkon)).Name;
24                         string value = ((JProperty)(jkon)).Value.ToString();
25                         row[name] = value;
26                     }
27                     table.Rows.Add(row);
28                 }
29           }
