如何将数组 [] 动态绑定到 DataGridTextColumn wpf

Question

当我有一个 Staff 类时，我想将 TB[] 绑定到 DataGrid 列 Staff.cs

public class Staff
{
    public string Name { get; set; }
    public float? Test_Score { get; set; }
    public float? Net_Income_Tax { get; set; }
    public float temp { get; set; }
    public float[] TB = new float[100];
    public float TB_Sum { get; set; }

}

在页面中，我的代码如下：

public ObservableCollection<Staff> Staff_Show = new ObservableCollection<Staff>();
public int StaffShowSize;

public TaxBefore_Sum(ObservableCollection<Staff> StaffAccept)
{

    InitializeComponent();
    Staff_Show = StaffAccept;
    StaffShowSize = Staff_Show.Count;


    DataGrid1.ItemsSource = this.Staff_Show;

    //this is to dynamiclly to create new DataGridTextColumn,but 
    //final ,only create the columns' header is"0",and no data to show,however,the TB[i] have data,but can't show like the picture
    for (int i = 0; i < StaffShowSize; i++)
    {
        DataGridTextColumn c = new DataGridTextColumn();
        c.Header = Convert.ToString(i + 1);
        c.Binding = new Binding("TB[i]");
        DataGrid1.Columns.Add(c);
    }
}

“for()”语句是动态创建新的DataGridTextColumn，但是 最后，只创建带有标题的列，没有数据显示，但是，TB[i]有数据，但不能像图片一样显示：

当我将代码更改为

c.Binding = new Binding("TB[" + i + "]");

显示

这就是你需要的……

c.Binding = new Binding("TB[" + i + "]");

也是结核病的定义...

public float[] TB { get; set; }  = new float[100];
