填充組合框

Question

我有如下的類：

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

我用它在我的形式是這樣的：

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}, 
    }; 

現在我要填補我combobox1從villages[]那它的DisplayMember=name和valueMember=pId

我已經試過這個，但不起作用。

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

Answer 1

在您需要定義屬性來公開的值村莊類，它不與歸檔成員的工作：

// 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; } 

這將解決這個問題：

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

Answer 2

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