ListView中没有显示所有的字母

您好，我有一个问题

如果你在看图片从下面的链接，我有一个CustomerFrame类（右）和一个ListView是MainForm类（在右边）

当我进入值的CustomerFrame上出现，但只有这样我的ListView"[]"在ListView

有谁知道为什么，我能做些什么？


这里有一些代码:

this is my add method from customerframe into mainform(listview)

 

private void MainForm_Load(object sender, EventArgs e)

 {

 CustomerFiles.Contact contact = new CustomerFiles.Contact();

 CustomerFiles.Address address = new CustomerFiles.Address();

 CustomerFrame customerframe = new CustomerFrame();

 

 

if (customerframe.ShowDialog() == DialogResult.OK) 

{

 listView1.Items.Add(contact.ToString(), address.ToString());

 }

 }

 

inside contact class

 

public override string ToString()

 {

 return string.Format("[{0}]", FullName);

 //PhoneData

 //EmailData

 //AddressData

 }

 

inside adress class

 

public override string ToString()

 {

 return string.Format("[{0}, {1}, {2}, {3}]", city, zipCode, country, street);

 }
