Question

public partial class MainWindow : Window
{
  public MainWindow()
  {
    InitializeComponent();

    List<Person> lista = new List<Person>();
    lista.Add(new Person(1, "Joao", 50.0f));
    lista.Add(new Person(2, "Maria", 150.0f));

    dataGrid1.ItemsSource = lista;
  }

  public class Person
  {
    public int id;
    public string name;
    public float salary;

    public Person(int id, string name, float salary)
    {
      this.id = id;
      this.name = name;
      this.salary = salary;
    }
  }
}

Answer 1

绑定通常是属性，而不是字段：

public int Id {get;set;}
public string Name {get;set;}
public decimal Salary {get;set;}

public Person(int id, string name, decimal salary)
{
    Id = id;
    Name = name;
    Salary = salary;
}

请注意 - Salary当然应该是decimal（不是float）。

如果您发现无法创建新Person条记录的行，请尝试添加无参数构造函数：

public Person() { Name = ""; }

DataBrid的数据绑定不起作用
