晕死了,NN 久了,很长时间不知道自己是了解还是不了解一个数据库的连接,今天还是自己手动的去写了一个,感觉还算好,没有那么多的难度。
using System;
using System.Collections.Generic;
using System.Text;
using System.Data.SqlClient;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
try
{
System.Data.SqlClient.SqlConnection sqlconnection;
System.Data.SqlClient.SqlCommand sqlcommand;
sqlconnection = new System.Data.SqlClient.SqlConnection();
sqlconnection.ConnectionString = "Data Source=(local);Initial Catalog=Northwind;User ID=sa";
sqlcommand = new System.Data.SqlClient.SqlCommand();
sqlcommand.Connection = sqlconnection;
sqlcommand.CommandText = "select * from orders where EmployeeID=5 and customerid='vinet'";
Console.WriteLine("loading...");
sqlconnection.Open();
SqlDataReader reader = sqlcommand.ExecuteReader();
while (reader.Read())
{
Console.WriteLine("{0}-{1}", reader["orderid"].ToString (), reader["customerid"].ToString ());
}
reader.Close();
sqlcommand.CommandText = "DELETE FROM ORDERS where ORDERID=455656";
Console.WriteLine(sqlcommand .ExecuteNonQuery ().ToString ());
sqlconnection.Close();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
}
代码全是自己写的,还好舒服多了。
小生刚学点,希望各位大虾以后给予支持。不要咒骂我哦,我知道这个很垃圾。。。
