将 JArray 转换为 datatable

DataTable 使用 Select 方法之后，把结果转换成 DataTable
/// <summary> /// 扩展DataTable Select结果为DataTable /// </summary> /// <remark> /// </remark> public DataTable DataTableSelect(this DataTable me, string where) { if (me == null || me.Rows.Count == 0) return me; var dtNew = me.Clone(); var drArray = me.Select(where); foreach (var item in drArray) dtNew.Rows.Add(item.ItemArray); return dtNew; } -
.net core 读取 appsettings.json 配置

Socket 获取以太网 IP（会筛掉虚拟网卡） 👍

Dns 获取 IP（只获取 IP V4 的外网 IP） 😄
