使用反射创建枚举 [英] Create enum using reflection

问题描述

确实 C＃提供一种方式来创建枚举键入从头使用反射？

Does C# offer a way to create Enum type from scratch using reflection?

假设，我有字符串的集合： {单身，已婚，离婚} ，我愿意建在运行以下枚举类型的 的

Suppose, I have a collection of strings: {"Single", "Married", "Divorced"} and I'm willing to build the following enum type in runtime:

enum PersonStatus
{
    Single, Married, Divorced
}

这是某种程度上可能吗？

Is this somehow possible?

推荐答案

不是没有做这样使用的Emit生成组件确实粗糙的东西。你会如何使用这样一个枚举呢？这里什么真正的目标。

Not without doing really gnarly things like generating assemblies using Emit. How would you use such an enum anyway? Whats the real goal here?

编辑：现在我们知道你真正想做的事情，的此页面建议您可以使用如下代码acheive你的目标：

Now that we know what you really want to do, this page suggests that you can acheive your goal using code like the following:

private void listViewComplex_CellEditStarting(object sender, CellEditEventArgs e)
{
    // Ignore edit events for other columns
    if (e.Column != this.columnThatYouWantToEdit)
        return;

    ComboBox cb = new ComboBox();
    cb.Bounds = e.CellBounds;
    cb.Font = ((ObjectListView)sender).Font;
    cb.DropDownStyle = ComboBoxStyle.DropDownList;
    cb.Items.AddRange(new String[] { "Single", "Married", "Divorced" });
    cb.SelectedIndex = 0; // should select the entry that reflects the current value
    e.Control = cb;
}
