关于组合框源代码的说明 [英] Explanation about source code of combobox

问题描述

我发现这个源代码允许我直接将ComboBox绑定到枚举值，但我不明白这个指令

  public  IList< UserType> UserTypes 
 {
  get  
 {
  //  将导致列表如{Tester，Engineer}  
  return 枚举。 GetValues（ typeof （UserType））。Cast< UserType>（）。ToList< UserType>（）; 
} 
} 
 
  public  UserType UserType 
 {
 获得; 
  set ; 
} 

知道这个代码我在 site



我尝试过的事情：



i尝试测试这段代码但是它有效但不明白。

解决方案

查看此CodeProject文章在WPF中绑定和使用友好的枚举 [ ^ ]



但如果您对所找到的代码有疑问，那么您应该将问题转到作者 [< a href =http://www.ridgesolutions.ie/index.php/2014/11该代码的/ 05 / wpf-xaml-binding-combobox-direct-to-enum-values /target =_ blanktitle =New Window> ^ ]

< blockquote>

枚举
 .GetValues（typeof（UserType））//获取枚举的所有值...这将返回一个对象数组
 .Cast< UserType>（） //将每个对象强制转换为枚举UserType  - 这将返回IEnumerable< UserType> 
 .ToList< UserType>（）; //转换IEnumerable< UserType>用户类型列表

这是非常基本的......就像问如何循环

I find this source code that allows me Binding ComboBox directly to enum values but I do not understand this instruction

public IList<UserType> UserTypes
{
    get
    {
        // Will result in a list like {"Tester", "Engineer"}
        return Enum.GetValues(typeof(UserType)).Cast<UserType>().ToList<UserType>();
    }
}
 
public UserType UserType
{
	get;
	set;
}

knowing that this code I find it in this site

What I have tried:

i try to test this code and it's works but don't understand that.

解决方案

Have a look at this CodeProject article Binding and Using Friendly Enums in WPF[^]

But if you have a query about the code you found then you should direct your questions to the authors[^] of that code

Enum 
    .GetValues(typeof(UserType)) // Get all values of the enum... This will return an array of object
    .Cast<UserType>()            // cast each object to enum UserType - This will return a IEnumerable<UserType>
    .ToList<UserType>();         // Convert the IEnumerable<UserType> to a list of UserTypes

This is pretty basic... It is like asking how to loop
