ASP.NET新人关于注册的问题

Question

每次点击注册时，它提示我错误。我检查不出来有啥错的。以下是我单击注册按钮的代码 protected void Button4_Click(object sender, EventArgs e)
{

    string usersex =" ";
    if (RadioButton3.Checked ==true )
       usersex = "男"; 
    else
      usersex = "女";
    string connString = System.Configuration.ConfigurationManager.ConnectionStrings["yhzlConnectionString"].ConnectionString;
    SqlConnection myConn = new SqlConnection(connString);
    string sqlStr = " insert into 用户资料(用户名,密码，权限，性别，地址) values('" + txtzcName.Text.ToString() + "','" + txtzcPasswork.Text.ToString() + "','" + 0 + "','" + usersex + "','" + txtadd.Text.ToString() + "') ";
    SqlCommand myCmd = new SqlCommand(sqlStr, myConn);
    myConn.Open();
    myCmd.ExecuteNonQuery();
    myConn.Close();


}

提示什么错误，是不是配置数据库链接符有问题？yhzlConnectionString这个在配置环境是怎么写的
