元组或多元字典？

Question

我公司拥有一批用于错误枚举，例如：

public enum LoginError 
{ 
    None = 0, 
    InvalidUsername, 
    InvalidPassword, 
} 

public enum CustomerError 
{ 
    None = 0, 
    NameRequired, 
    SurnameRequired, 
} 

每个枚举，我想有存储在列表中的描述，这样我就可以做这样的事情：

string desc = errorList(typeof(LoginError), myError.LoginError); //or something similar 

如果我使用多键词典或元组，它会起作用吗？任何示例显示如何做到这一点？

Answer 1

您可以使用一个枚举full name string作为重点。

Dictionary<string,string> map; 

private string GetEnumName(Enum _enum) 
{ 
    return string.Format("{0}.{1}", _enum.GetType().Name, _enum.ToString()); 
} 

void RegisterMapping(Enum @enum, string displayName) 
{ 
    var enumName= GetEnumName(@enum); 
    map.Add(enumName, displayName); 
} 

Answer 2

我认为这会为你工作，

public enum LoginError 
     { 
      None = 0, 
      InvalidUsername, 
      InvalidPassword, 
     } 

     public enum CustomerError 
     { 
      None = 0, 
      NameRequired, 
      SurnameRequired, 
     } 

     private static void Main(string[] args) 
     { 
      Dictionary<Enum, string> myErrorDictionary = new Dictionary<Enum, string>(); 

      myErrorDictionary.Add(LoginError.None, "This is None from Login Error"); 
      myErrorDictionary.Add(LoginError.InvalidUsername, "Invalid username"); 
      myErrorDictionary.Add(LoginError.InvalidPassword, "Invalid Password"); 

      myErrorDictionary.Add(CustomerError.None, "This is None from Custom Error"); 
      myErrorDictionary.Add(CustomerError.NameRequired, "Name Required"); 
      myErrorDictionary.Add(CustomerError.SurnameRequired, "Surname Required"); 

      Console.WriteLine(myErrorDictionary[LoginError.None]); 
      Console.WriteLine(myErrorDictionary[CustomerError.None]); 

      Console.Read(); 
     }
