在SelectList中組合2個字段

Question

目前我有SelectList，它會寫入ID，並在窗體上顯示FirstName。

ViewBag.Person = new SelectList(db.Person, "ID", "FirstName"); 

如何將FirstName和LastName連接到SelectList中？喜歡的東西：

ViewBag.Person = new SelectList(db.Person, "ID", "FirstName & LastName"); 

Answer 1

嘗試這樣：

ViewBag.Person = 
new SelectList((from s in db.Person select new { 
    ID=s.ID, 
    FullName = s.FirstName+ " " + s.LastName}), 
    "ID", 
    "FullName", 
    null); 

或添加新的屬性，以您的Person模型

public string Fullname 
{ 
    get 
    { 
     return string.Format("{0} {1}", FirstName, LastName); 
    } 
}
