我这台电脑上只有vs2005,SQL Server 在本地局域网内的另一太主机上，我想把VS连到主机上的SQL Server ,请问下连接字符串该怎么写呢??
PS:我查了下，网上很多说用driver,不过不支持

public partial class kaipiaoziliao_loginpage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection();
con.ConnectionString = " Server=i-server;database=fapiao;integrated security=SSPI;";

SqlCommand objcmd = new SqlCommand();
objcmd.Connection = con;
objcmd.CommandText = "select shuihao from cheeck where shuihao＝'" + Convert.ToInt32(TextBox1.Text.Trim()) + "'";
con.Open();
SqlDataReader dr = objcmd.ExecuteReader();
if (dr.Read())
{
Session["shuihao"] = TextBox1.Text.Trim();
Response.Redirect("cheeck.aspx");
}
else
{ Response.Write("<script language='javascript'>window.alert('您的输入有误，请重新输入！');</script>"); }
}

}
上面的是我的程序段,不过运行时都出现 SqlDataReader dr = objcmd.ExecuteReader();这一行的错误,是不是因为数据库没连上的缘故??求教~~在线等
