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;View Code
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Insus.NET.Models;
namespace Insus.NET.Entities
{
public class CustomerEntity
{
public DataTable Customers()
{
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("CustomerID", typeof(int)));
dt.Columns.Add(new DataColumn("CustomerName", typeof(string)));
dt.Columns.Add(new DataColumn("PID", typeof(string)));
DataRow dr = dt.NewRow();
dr["CustomerID"] = 9; dr["CustomerName"] = "张三"; dr["PID"] = "123456789012";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["CustomerID"] = 10; dr["CustomerName"] = "李四"; dr["PID"] = "321245677812";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["CustomerID"] = 30; dr["CustomerName"] = "吴广"; dr["PID"] = "213445678912";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["CustomerID"] = 35; dr["CustomerName"] = "王维"; dr["PID"] = "334456789012";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr["CustomerID"] = 36; dr["CustomerName"] = "赵勇"; dr["PID"] = "213445678912";
dt.Rows.Add(dr);
return dt;
}
}
}
......
方法很多,你可以择优使用。
