#region 将datatable转换成json数组 System.Collections.ArrayList dic = new System.Collections.ArrayList(); DataTable dt = null; DataTable dtNew = null; DataRow[] drArr = null; if (dataSet.Tables.Count > 0) { dt = dataSet.Tables[0]; drArr = dt.Select(""); //按条件查询,只能查询当前页,查询所有数据sql语句已经写了 dtNew = dt.Clone(); for (int i = 0; i < drArr.Length; i++) { dtNew.ImportRow(drArr[i]); } } foreach (DataRow dr in dtNew.Rows) { System.Collections.Generic.Dictionary<string, object> drow = new System.Collections.Generic.Dictionary<string, object>(); foreach (DataColumn dc in dt.Columns) { //drow.Add($"{dc.ColumnName}", dr[dc.ColumnName]); drow.Add(dc.ColumnName, StampToDateTime(Convert.ToString(dr[dc.ColumnName]))); } dic.Add(drow); } #endregion
