将 GridControl 绑定到 SortedList

Question

我试图将一个表（特别是 DevExpress GridControl）绑定到 SortedList。我希望表的第一列绑定到 SortedList 的键，第二列绑定到 SortedList 的键中对象的字段，例如，

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        InitializeTable();
    }

    public void InitializeTable()
    {
        SortedList<DateTime, Dividend> EquityDividends = new SortedList<DateTime, Dividend>();

        EquityDividends.Add(new DateTime(2011, 1, 12, 16, 30, 00, DateTimeKind.Local), new Dividend(new DateTime(2011, 1, 12, 16, 30, 00, DateTimeKind.Local), "120", 12, new TimeSpan(4, 0, 0)));
        EquityDividends.Add(new DateTime(2011, 1, 13, 16, 30, 00, DateTimeKind.Local), new Dividend(new DateTime(2011, 1, 12, 16, 30, 00, DateTimeKind.Local), "125", 12, new TimeSpan(4, 0, 0)));

        gridControl1.DataSource = new BindingSource() { DataSource = EquityDividends };

        bandedGridView1.Columns[1].FieldName = "ExpectedDividend";
    }
}

public class Dividend
{
    public DateTime InDividendDate;
    public string ExpectedDividend;
    public double Adjustment;
    public TimeSpan TimeRemaining;

    public Dividend(
        DateTime InDividendDate,
        string ExpectedDividend,
        double Adjustment,
        TimeSpan TimeRemaining)
    {
        this.InDividendDate = InDividendDate;
        this.ExpectedDividend = ExpectedDividend;
        this.Adjustment = Adjustment;
        this.TimeRemaining = TimeRemaining;
    }
}

这不太有效（键来自出现在第 0 列中，字符串“WindowsFormsApplication10.Dividend”出现在第 1 列中）。有人有什么建议吗？

Answer 1

只需重写类 Dividend 的方法 ToString() 并返回您想要的值，如下所示：

public override string ToString()
{
    return "MyValue";
}

您将获得一列包含键和一列包含从 < 返回的值代码>ToString()。
