綁定到DataGridView的集合

Question

我想綁定我的綁定列表到DataGridView，但並非所有東西都顯示了！這是我的代碼目前有：除外Person.numbers沒有在DataGridView顯示（僅ID，FName參數& LName的）事實

public class Person 
{ 
    public int ID { get; set; } 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 
    public int[] numbers = new int[6] 
} 

public class Data 
{ 
    public static BindingList<Person> persons = new BindingList<Person>(); 
} 

... 

var bl = new BindingList<Person>(persons); 
myGrid.DataSource = bl; 

一切的偉大工程！

任何想法，爲什麼？

我會盡量讓它成爲一個屬性。編輯：要格式化以便在datagridview中使用，可以使用Singleton模式並將列綁定到格式化字符串，如下例所示。

public class Person 
{ 
    public int ID { get; set; } 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 
    public String NumbersString { get; set; } 

    private int[] _numbers; 
    public int[] Numbers 
    { 
     get 
      { 
       return _numbers; 
      } 
     set 
      { 
       _numbers = value; 
       NumbersString = FormatIntoString(_numbers); 

      } 

    } 

    public Person() 
    { 
    numbers = new int[6]; 

    } 


// The write the method that puts the array into a readable form 

private string FormatIntoString(int[] array) 
    { 
    string result = ""; 

    foreach(var x in array) 
     { 
     result += x.ToString() + ","; 
     } 
    return result; 
    }
