今天偶尔有个东西要用到2维数组，发现不会，搞来搞去搞了半天，还是上网google了资料。
      总结一下。
      定义变量的方法，
      private string[] ColumnsList = {
            "序号|rowid","主帐户|masteraccount","主帐号|childaccount","卡号|cardno",
            "户名|name","客户号|crmid","科目号|stocktype",
            "原金额|orgincount","发生额|currcount","新金额|newcount","状态|state"
        };
        private string[,] dataList = {
            {"1","6624885718651234","000001","057400000000000001","张三风","32240001","805001","100","1","101","正常"},
            {"2","6624885718651234","000002","057400000000000002","张三风","32240002","805001","1000","94","1094","正常"},
            {"3","6624885718651234","000003","057400000000000003","张三风","32240003","805001","109","9","118","挂失"},
            {"4","6624885718651234","000004","057400000000000004","张三风","32240004","805001","234","5","239","注销"},
        };
        遍历添加到Table中
         DataTable dt = new DataTable();
            for(int i=0;i            {
                string[] templist = ColumnsList[i].Split('|');
                if (templist.Length != 2) continue;
                dt.Columns.Add(templist[1].Trim(), typeof(string));
            }
            dt.AcceptChanges();

            for (int i = 0; i < 4; i++)
            {
                DataRow dr = dt.NewRow();
                for(int j=0;j                {
                    string[] templist = ColumnsList[j].Split('|');
                    if (templist.Length != 2) continue;
                    dr[templist[1].Trim()] = dataList[i, j].Trim();
                }
                dt.Rows.Add(dr);
            }
            dt.AcceptChanges();
    记一下，防止以后忘记！
