    //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("]"));
    //获取数据   
    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(&#39;*&#39;);
 //创建表   
 if (tb == null)
 {
     tb = new DataTable();
     tb.TableName = strName;
     foreach (string str in strRows)
     {
  var dc = new DataColumn();
  string[] strCell = str.Split(&#39;#&#39;);
  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();
 }
 //增加内容   
 DataRow dr = tb.NewRow();
 for (int r = 0; r < strRows.Length; r++)
 {
     dr[r] = strRows[r].Split(&#39;#&#39;)[1].Trim().Replace(",", ",").Replace(":", ":").Replace("\"", "");
 }
 tb.Rows.Add(dr);
 tb.AcceptChanges();
    }
    return tb;
