C#怎么取到datatable中数据的每一列的标题部分？

我动手给你写的一个代码示例，希望对你有帮助：

 

Code：

 

                DataTable dt = new DataTable();
                dt.Columns.Add("姓名");
                dt.Columns.Add("年龄");
                dt.Columns.Add("性别");

                DataRow dr;

                dr = dt.NewRow();
                dr["姓名"] = "张三";
                dr["年龄"] = "21";
                dr["性别"] = "男";
                dt.Rows.Add(dr);

                dr = dt.NewRow();
                dr["姓名"] = "李四";
                dr["年龄"] = "22";
                dr["性别"] = "男";
                dt.Rows.Add(dr);

                foreach (DataColumn c in dt.Columns)
                {
                    Console.WriteLine(c.ColumnName);//输出列名
                }

                foreach (DataRow r in dt.Rows)
                {
                    Console.WriteLine(r["姓名"].ToString() + r["年龄"].ToString() + r["性别"].ToString());//输出各行记录
                }
