winforms - 使用 bindingsource 填充组合框

Question

在 windows 窗体上，所有文本框和组合框都是从 acctPackageBindingSource 绑定的。我在仅显示 int 值的组合框中绑定的问题意味着它来自 acctPackage 。我想显示名称意味着该值的“显示成员”。那个来自不同的表名是sysCode。那么如何才能完美地显示显示成员。下面是我的代码

 // Here the all value is coming form Syscode table .

  public void FillDropDown()
    {
        if (_commonComponent == null)
            _commonComponent = new CommonComponent();

        List<SysCode> _syscode = _commonComponent.GetByTableCodeForIncomeDedMapping("19");
        bindingSourceSysCode.DataSource = _syscode;

        packageCodeComboBox.DataSource = bindingSourceSysCode;
        packageCodeComboBox.DisplayMember = "Desclong2";
        packageCodeComboBox.ValueMember = "PackageCode";

    }



//This part is bind my all value on the form 

  private void FillAcctPackage()
    {
        if (_commonComponent == null)
            _commonComponent = new CommonComponent();

        acctPackageBindingSource.DataSource = _commonComponent.GetAcctPackge();



    }
