C# 用代码创建 DataSet 和 DataTable 的列和记录

System.Data.DataSet objSet = new DataSet(); 
System.Data.DataTable objTable = new DataTable("test"); 
objTable.Columns.Add("CodeID", typeof(string)); 
objTable.Columns.Add("FilterCitem ", typeof(string)); 
objTable.Columns.Add("FilterSqlStr", typeof(string)); 

System.Data.DataRow dr = objTable.NewRow(); 
dr[0] = "row0andcol0"; 
dr[1] = "row2andcol2"; 
dr[2] = "row3andcol3"; 
objTable.Rows.Add(dr); 
objSet.Tables.Add(objTable);
