如何檢索一個列值從一個表使用asp .net mvc 4

Question

我有一個表，我想從一列（mailid）檢索所有的值。在表中兩列是可用的是id和mailid。 我想將郵件發送給本欄中所有可用郵件標識的人員。

   mstEmpAdmin m = new mstEmpAdmin(); 


       var m2=(from e in db.mstEmpAdmins 
       select new 
       { 
        txtEmpAdminEmailId = e.txtEmpAdminEmailId, 
       }); 
       CustomMailService mail = new CustomMailService(); 

       string Subject = "Domestic Travel Request"; 
       string Body = "Hi Sir/Madam,My "; 
       mail.Mail(m2,Subject, Body); 

的形式，它是顯示在最後一行的錯誤上面的代碼，我在想什麼是我將存儲人的郵件ID在一個對象，然後在發送電子郵件，我將通過該對象。

我可以這樣嗎？任何解決方案？

我得到了輸出。

  List<mstEmpAdmin> adminlist = (from st in db.mstEmpAdmins 
               select st).ToList(); 
       foreach (var item in adminlist) 
       { 

        string Subject = "Request for Business Card"; 
        string Body = "Hello Sir/Madam ," + "\n" + " " + bc.txtFirstName + " " + "You have requested for Business Card" + " " + "Total no of Quantity :" + bc.intQuantity + " "; 
        CustomMailService mail = new CustomMailService(); 

        mail.Mail(item.txtEmpAdminEmailId, Subject, Body); 
       }
