c# - 从结构数组填充组合框

Question

我有一堂课如下：

class villages { public string name; public int pId; }

我以这样的形式使用它：

private villages[] centerVillage=new villages[]{
        new villages{name= "village1",pId=0},
        new villages{name= "village2",pId=1},
        new villages{name= "village3",pId=2},
        new villages{name= "village4",pId=3},
        new villages{name= "village5",pId=4},
        new villages{name= "village6",pId=5},
        new villages{name= "village7",pId=6},
    };

现在我想combobox1从villages[]它DisplayMember=name和valueMember=pId

我已经尝试过了，但不起作用。

combobox1.DataSource = new BindingSource(centerVillage, null);
combobox1.DisplayMember = "name";
combobox1.ValueMember = "pId";

Answer 1

在村庄类中，您必须定义属性以公开值，它不适用于归档成员：

    // Exceptions:
    //   System.ArgumentException:
    //     The specified property cannot be found on the object specified by the System.Windows.Forms.ListControl.DataSource
    //     property.
    public string ValueMember { get; set; }

这将解决问题：

    class villages
    {
        public string name { get; set; }
        public int pId { get; set; }
    }

Answer 2

combobox1.DataSource = villages;
combobox.DisplayMember = "name";
combobox1.ValueMember = "pId";
