我控制器代码
public ActionResult BugHistory(BugTracker_DataHelper bugdatahelepr, string loginname, string EmployeName)
{
Session["UserName"] = "aaaa";
loginname = Session["UserName"].ToString();
//bugdatahelepr.Username = loginname.ToString();
//var username = bugdatahelepr.Username;
SqlConnection connection = new SqlConnection(@"Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MvcBugTracker;Data Source=SSDEV6\SQLEXPRESS");
connection.Open();
SqlCommand cmd = new SqlCommand("select ResourceName from Resources where UserName =" + loginname, connection);
SqlDataReader dr = cmd.ExecuteReader();
if (dr.Read())
{
bugdatahelepr.FixedByID = Convert.ToInt16(dr["ResourceName"]);
//updatemodel.ProjectId = Convert.ToInt16(dr["ProjectId"]);
}
else
{
dr.Close();
}
dr.Close();
connection.Close();
//ViewBag.BugHistoryId = new SelectList(ToStatusDropdown(), "BugHistoryId", "ToStatus");
//ViewData.AssignedToID=new SelectList()
return View();
}

当我登录页面用户名aaaa获取资源名称。任何人都可以帮我做到这一点?
IN veiw page i Diplay like this
FixedBYID -----------raghu <---Lable in disabale
AssignedBY ID-------- anil <----dropdownlist in disable
从错误中看,问题是它试图在数据库中找到列“aaaa”,而不是列“username”。 – 2012-07-24 07:23:59
@GarrettFogerlie ...这是我的查询“从资源中选择ResourceName,其中UserName =”+ loginname, – 2012-07-24 07:25:15
@GarrettFogerlie ..我在数据库中获得用户名相同,即使得到这种类型的错误来了......我该怎么做.. – 2012-07-24 07:28:40
