本文執行個體講述了C#實現將json轉換為DataTable的方法。分享給大家供大家參考。具體實現方法如下:
#region 將json轉換為DataTable/// <summary>/// 將json轉換為DataTable/// </summary>/// <param name="strJson">得到的json</param>/// <returns></returns>private DataTable JsonToDataTable(string strJson){ //轉換json格式 strJson = strJson.Replace(",\"", "*\"").Replace("\":", "\"#").ToString(); //取出表名 var rg = new Regex(@"(?<={)[^:]+(?=:\[)", RegexOptions.IgnoreCase); string strName = rg.Match(strJson).Value; DataTable tb = null; //去除表名 strJson = strJson.Substring(strJson.IndexOf("[") + 1); strJson = strJson.Substring(0, strJson.IndexOf("]")); //擷取資料 rg = new Regex(@"(?<={)[^}]+(?=})"); MatchCollection mc = rg.Matches(strJson); for (int i = 0; i < mc.Count; i++) { string strRow = mc[i].Value; string[] strRows = strRow.Split('*'); //建立表 if (tb == null) { tb = new DataTable(); tb.TableName = strName; foreach (string str in strRows) { var dc = new DataColumn(); string[] strCell = str.Split('#'); if (strCell[0].Substring(0, 1) == "\"") { int a = strCell[0].Length; dc.ColumnName = strCell[0].Substring(1, a - 2); } else { dc.ColumnName = strCell[0]; } tb.Columns.Add(dc); } tb.AcceptChanges(); } //增加內容 DataRow dr = tb.NewRow(); for (int r = 0; r < strRows.Length; r++) { dr[r] = strRows[r].Split('#')[1].Trim().Replace(",", ",").Replace(":", ":").Replace("\"", ""); } tb.Rows.Add(dr); tb.AcceptChanges(); } return tb;} #endregion
希望本文所述對大家的C#程式設計有所協助。
