public partial class vote : System.Web.UI.Page
{

private string voteId = "1";

protected void Page_Load(object sender, EventArgs e)
{

SqlConnection con = DB.creatConnection();
con.Open();
SqlCommand cmd = new SqlCommand("select voteTitle from voteMaster where voteId"+ this.voteId, con);
string title = Convert.ToString(cmd.ExecuteScalar());
this.lab1.Text = title;

}

}



用户代码未处理 System.Data.SqlClient.SqlException
Message="第 1 行: 'voteId1' 附近有语法错误。"

voteID 是数据库中投票的ID

public partial class vote : System.Web.UI.Page
{

private string voteId = "1";

protected void Page_Load(object sender, EventArgs e)
{

SqlConnection con = DB.creatConnection();
con.Open();
SqlCommand cmd = new SqlCommand("select voteTitle from voteMaster where voteId=‘"+ this.voteId+“’”, con);
string title = Convert.ToString(cmd.ExecuteScalar());
this.lab1.Text = title;

}

}

SqlCommand cmd = new SqlCommand("select voteTitle from voteMaster where voteId"+ this.voteId, con);
少了一个等号
改为：
SqlCommand cmd = new SqlCommand("select voteTitle from voteMaster where voteId="+ this.voteId, con);

谢谢了

真大意呀
