我有一个包含 4 列的 DataTable。 (ID、测试名称、测试结果、IsValidRequest)。我想将 TestName 和 Testresult 转换为 json。
string json = Newtonsoft.Json.JsonConvert.SerializeObject(dt);
变量“json”中的当前 JSON:

请提出任何解决方案？
最佳答案
先将DataTable转为Dictionary，再序列化为json。
Dictionary<string, string> dict =
dt.AsEnumerable()
.ToDictionary<DataRow, string, string>(row => row.Field<string>(1),
row => row.Field<string>(2));
string json = Newtonsoft.Json.JsonConvert.SerializeObject(dict);
