多个文本框2方式绑定

也许标题不正确，但我不知道如何提问。我有一个Windows窗体的多个选项卡，使用单例。我的表单大约有50多个文本框，这些文本框将用户输入存储到我的singleton属性中，然后保存为xml。我的问题是，读取XML并在文本框上显示的不太复杂的路径是什么保存到XML中?示例代码:

public class ContactInfo
   {
    public string Name { get { return Firstname + " " + LastName; } }
    public string Firstname { get; set; }
    public string LastName { get; set; }
    public string PhoneNumber { get; set; }
    public string Email { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string ZipCode { get; set; }
   }
public class Site
{
Site()
 {
        OfficeAddress = new ContactInfo();
        ShippingAddress = new ContactInfo();
        DirectorOfOperationsFandB = new ContactInfo();
        DirectorOfOperationsRetail = new ContactInfo();
        SecondInCharge = new ContactInfo();
        SiteController = new ContactInfo();
        SiteContact = new ContactInfo();
  }
    public ContactInfo OfficeAddress { get; set; }
    public ContactInfo ShippingAddress { get; set; }
    public ContactInfo DirectorOfOperationsFandB { get; set; }
    public ContactInfo DirectorOfOperationsRetail { get; set; }
    public ContactInfo SecondInCharge { get; set; }
  }

我开始做textbox1。text = site . officeaddress . address1;等等但是你无法想象这要占用多少行

textBox1.DataBindings.Add(new Binding("Text", ds, "customers.custName"));
