如何将组合框与Enum绑定 [英] how to bind combobox with Enum

问题描述

我想知道如何将组合框与Enum绑定，那么数据源是什么，

显示成员和值会员。?????



我刚尝试使用代码

 public Enum MyEnumType 
 {
 [说明（A）] 
 A = 1，
 [说明（B）] 
 B = 2，
 
} 
 comboBox2.DataSource = Enum.GetValues（typeof（MyEnumType））; 
 comboBox1.DisplayMember =Value; 
 comboBox1.ValueMember =Key; 

干杯，

你可以找到两个有点长但非常全面的答案我的文章：



枚举类型不会枚举！解决.NET和语言限制 [ ^ ]，

人类可读的枚举元数据 [ ^ ]。

-SA

这里有一篇文章解释这个：数据绑定带有描述的枚举 [ ^ ]

最后我得到了解决方案，它正在工作.....



public Enum MyEnumType

{

[Description（A）]

A = 1，

[描述（B）]

B = 2，

}

字典< string，int> dictionary = new Dictionary< string，>（）;



foreach（int enumValue in

Enum.GetValues（typeof（MyEnumType）） ）

{

dictionary.Add（Enum.GetName（typeof（MyEnumType），enumValue），enumValue）;

}



ComboBox1.DisplayMember =Key;;

ComboBox1.ValueMember =Value;

ComboBox1.DataSource = new的BindingSource（字典，NULL）;

解决方案

You can find somewhat long but a very comprehensive answer in two of my articles:

Enumeration Types do not Enumerate! Working around .NET and Language Limitations[^],
Human-readable Enumeration Meta-data[^].

—SA

There is an article explaining this here: Data Binding an Enum with Descriptions[^]

Finally i have got the solution,Its working.....

public Enum MyEnumType
{
[Description("A")]
A= 1,
[Description("B")]
B= 2,
}
Dictionary<string,int> dictionary=new Dictionary<string,>();

foreach (int enumValue in
Enum.GetValues(typeof(MyEnumType)))
{
dictionary.Add(Enum.GetName(typeof(MyEnumType),enumValue),enumValue);
}

ComboBox1.DisplayMember = "Key";;
ComboBox1.ValueMember = "Value";
ComboBox1.DataSource = new BindingSource(dictionary,null);
