使用Newtonsoft JsonConvert反序列化Json数据到DataTable

要用到Newtonsoft.Json.dll

简单了解JArray和JObject

string json = @"[
            { id: 1, title: '必订款', no: 'bdk', flag_ka: 'y' },
            { id: 2, title: '必订规格', no: 'bdgg', flag_ka: 'n' }
        ]";
Newtonsoft.Json.Linq.JArray array = Newtonsoft.Json.JsonConvert.DeserializeObject(json) as JArray;
for (int i = 0; i < array.Count; i++)
{
    JObject obj = array[i] as JObject;
    int id = Convert.ToInt32(obj["id"]);
    var title = obj["title"];
}

Json转DataTable

string json = @"[
            { id: 1, title: '必订款', no: 'bdk', flag_ka: 'y' },
            { id: 2, title: '必订规格', no: 'bdgg', flag_ka: 'n' }
        ]";
Newtonsoft.Json.Linq.JArray array = Newtonsoft.Json.JsonConvert.DeserializeObject(json) as JArray;
StringBuilder columns = new StringBuilder();
DataTable table = new DataTable();
JObject objColumns = array[0] as JObject;
//构造表头
foreach (JToken jkon in objColumns.AsEnumerable<JToken>())
{
    string name = ((JProperty)(jkon)).Name;
    columns.Append(name + ",");
    table.Columns.Add(name);
}
//向表中添加数据
for (int i = 0; i < array.Count; i++)
{
    DataRow row = table.NewRow();
    JObject obj = array[i] as JObject;
    foreach (JToken jkon in obj.AsEnumerable<JToken>())
    {
        string name = ((JProperty)(jkon)).Name;
        string value = ((JProperty)(jkon)).Value.ToString();
        row[name] = value;
    }
    table.Rows.Add(row);
}
