将枚举绑定到 WinForms 组合框，然后对其进行设置 [英] Binding an enum to a WinForms combo box, and then setting it

问题描述

很多人已经回答了如何在WinForms中将枚举绑定到组合框的问题.是这样的:

a lot of people have answered the question of how to bind an enum to a combo box in WinForms. Its like this:

comboBox1.DataSource = Enum.GetValues(typeof(MyEnum));

但是如果无法设置要显示的实际值，那将毫无用处.

But that is pretty useless without being able to set the actual value to display.

我试过了:

comboBox1.SelectedItem = MyEnum.Something; // Does not work. SelectedItem remains null

我也试过:

comboBox1.SelectedIndex = Convert.ToInt32(MyEnum.Something); // ArgumentOutOfRangeException, SelectedIndex remains -1

有人知道如何做到这一点吗?

Does anyone have any ideas how to do this?

推荐答案

The Enum

public enum Status { Active = 0, Canceled = 3 }; 

从中设置下拉值

cbStatus.DataSource = Enum.GetValues(typeof(Status));

从所选项目中获取枚举

Status status; 
Enum.TryParse<Status>(cbStatus.SelectedValue.ToString(), out status);
