c# - 选择的组合框项目待修复

Question

我的 Windows 窗体中有一个数据绑定(bind)组合框，我通过函数 deptload() IN FORM LOAD 填充它

public void DeptcomboLoad()
        {
            DataTable dt = depttrans.getDeptName();
            Cmb_Department.DataSource = dt;
            Cmb_Department.DisplayMember = "DepartmentName"; //CHAR
            Cmb_Department.ValueMember = "DepartmentPK"; //INT 
        }

现在，当一个部门的员工(比如账户 DepartmentName="Accounts "， DepartmentPK=23 )登录时，我希望 ComboBox 文本被选为 "acounts " 当我去获取 ComboBox 的选定值时，我应该得到 23

我试过了

Cmb_Department.selectedtext="Accounts"
Cmb_Department.Text="Accounts"

但它没有给出选定的值

谁能给个建议

Answer 1

与其尝试将值放入组合框，不如尝试像这样获取 SelectedItem:

string txt= Cmb_Department.SelectedItem.Text

或者只是:

string txt= Cmb_Department.SelectedText
