如何往dataTable dt new DataTable()中添加两列（a和b）,并加一条记录(a=al,b=bl)

[心蓝无敌]

DataTable dt = new DataTable();
dt.Columns.Add("a");
dt.Columns.Add("b");
DataRow dr =dt.NewRow();
dr["a"] = "a";
dr["b"] = "b";
dt.Rows.Add(dr);

这些东西你可以翻翻sdk就知道了。

DataColumn dc;
dc = new DataColumn("a", System.Type.GetType("System.Int32"));
dt.Columns.Add(dc);
dc = new DataColumn("b", System.Type.GetType("System.Int32"));
dt.Columns.Add(dc);

DataRow dr;

dr = dt.NewRow();
dr["a"] = a1;
dr["b"] = b1;

dt.Rows.Add(dr);

   DataTable dt =  new   DataTable();
            DataColumn dcA =new DataColumn("a");
            DataColumn dcB = new DataColumn("b");
            dt.Columns.Add(dcA);
            dt.Columns.Add(dcB);
            DataRow dr = dt.NewRow();
            dr["a"] = "al";
            dr["b"] = "bl";
            dt.Rows.Add(dr);
