中获取DataTable选择第⼀⾏某⼀列值数据源是⼀个DataTable，现在我们需要获取这个DataTable的第⼀⾏第⼀列的值。先准备⼀个数据集，创建⼀个DataTable，并填充数据：source code:using System;using c;using ;using ;using ;using ;using ;namespace es{ public class CustomerEntity { public DataTable Customers() { DataTable dt = new DataTable(); (new DataColumn("CustomerID", typeof(int))); (new DataColumn("CustomerName", typeof(string))); (new DataColumn("PID", typeof(string))); DataRow dr = (); dr["CustomerID"] = 9; dr["CustomerName"] = "张三"; dr["PID"] = "2"; (dr); dr = (); dr["CustomerID"] = 10; dr["CustomerName"] = "李四"; dr["PID"] = "321245677812"; (dr); dr = (); dr["CustomerID"] = 30; dr["CustomerName"] = "吴⼴"; dr["PID"] = "2"; (dr); dr = (); dr["CustomerID"] = 35; dr["CustomerName"] = "王维"; dr["PID"] = "334456789012"; (dr); dr = (); dr["CustomerID"] = 36; dr["CustomerName"] = "赵勇"; dr["PID"] = "2"; (dr); return dt; } }}⽅法⼀，使⽤LINQ和Lambda:上⾯是先获取第⼀⾏，再从获取的⾏中取得某⼀值。⽅法⼆：⽅法三：或者：⽅法四：创建⼀个对象：把DataTable转换为这个对象集合：......⽅法很多，你可以择优使⽤。以上所述是⼩编给⼤家介绍的获取DataTable选择第⼀⾏某⼀列值，希望对⼤家有所帮助，如果⼤家有任何疑问请给我留⾔，⼩编会及时回复⼤家的。在此也⾮常感谢⼤家对⽹站的⽀持！
