{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
/*
* connect to Sql Server
*/
string strConnection = "Data Source=ZRQ-PC;";
strConnection+="Initial Catalog=master;Integrated Security=True";
SqlConnection objConnection = new SqlConnection(strConnection);
objConnection.Open();
objConnection.Close();
/**************************************************************/
/*
* connect to access table
*/
//string strConnection = "Provider=Microsoft.Jet.OleDb.4.0;";
//strConnection += @"Data Source=C:\Users\ZRQ\Documents\STU.accdb";
//OleDbConnection objConnection = new OleDbConnection(strConnection);
//objConnection.Open();
//objConnection.Close();
/**************************************************************/
/*
*as for connect to Oracle or MySql 等我学了再说吧……(*^__^*)
*/
}
}
}
其中的简易办法：
在“服务器资源管理器”中选择要连接的数据，then看它的属性中Name，copy to strConnection 即可~
