從SQL Server檢索一行到Windows Phone

Question

我正在使用此代碼在SQL Server中搜索數據。但結果是返回列表，我應該返回它只獲得一行？意味着我要使用文本塊結合來獲得，而無需使用列表框模板記錄..

public List<Customer> FindProfile(string custemail) 
{ 
    var findprofile = from r in cust.Customers where r.CustEmail == custemail select r; 
    return findprofile.ToList(); 
} 

public List<Customer> GetProfileData() 
{ 
    var profiledata = from r in cust.Customers 
         select r; 
    return profiledata.Take(5).ToList(); 
} 

public pgProfile() 
{ 
    InitializeComponent(); 
    proxy.FindProfileCompleted += new EventHandler<FindProfileCompletedEventArgs>(proxy_FindProfileCompleted); 
    proxy.FindProfileAsync(custemail); 
} 

void proxy_FindProfileCompleted(object sender, FindProfileCompletedEventArgs e) 
     { 
      ListBox1.ItemsSource = e.Result; 
     } 

Answer 1

你就不能使用.First()或.FirstOrDefault()獲取返回客戶的名單上？

List<Customer> customers = GetProfileData(); 

// get just the first customer: 
Customer first = customers.First();
