private void button1_Click(object sender, EventArgs e)
{
string connString = "Data Source=WWW-42ECAADACF3\\SQLEXPRESS;Initial Catalog=MySchool;Integrated Security=True";
SqlConnection connection = new SqlConnection();
connection.Open();
MessageBox.Show("连接成功");
}
运行后，错误提示出现一连串的乱码，怎么解决

string connString = "Data Source=WWW-42ECAADACF3\\SQLEXPRESS;Initial Catalog=MySchool;Integrated Security=True";
SqlConnection connection = new SqlConnection();
connection.Open();

SqlConnection connection = new SqlConnection(这里放参数····connString );
string connString = "Data Source=WWW-42ECAADACF3\\SQLEXPRESS;Initial Catalog=MySchool;Integrated Security=True";
好象Integrated Security=True后面还要有登录SQL的账号密码,把它等于false看看
呵呵，你前面定义了一个connString是对的
但是后面：
SqlConnection connection = new SqlConnection();
Sqlconnection()把connString放在括号里面，这样才行，
要不然的话，程序知道你要连到什么地方吗？？
改一下就好了
