如何设置组合框中选定的值？

我在 C# Windows 窗体中使用组合框。我绑定的项目列表如下：

var employmentStatus = new BindingList<KeyValuePair<string, string>>();

employmentStatus.Add(new KeyValuePair<string, string>("0", "[Select Status]"));
employmentStatus.Add(new KeyValuePair<string, string>("1", "Contract"));
employmentStatus.Add(new KeyValuePair<string, string>("2", "Part Time"));
employmentStatus.Add(new KeyValuePair<string, string>("3", "Permanent"));
employmentStatus.Add(new KeyValuePair<string, string>("4", "Probation"));

employmentStatus.Add(new KeyValuePair<string, string>("5", "Other"));
cmbEmployeeStatus.DataSource = employmentStatus;
cmbEmployeeStatus.ValueMember = "Key";
cmbEmployeeStatus.DisplayMember = "Value";
cmbEmployeeStatus.SelectedIndex = 0;

我将选定的值保存在数据库中，例如 1 或 2。现在我想从数据库项中设置选定的值，例如：

cmbEmployeeStatus.SelectedValue =employee.employmentstatus;     

但组合框未选择值。我怎样才能做到这一点？

试试这个。

cmbEmployeeStatus.SelectedIndex = cmbEmployeeStatus.FindString(employee.employmentstatus);
