Question

我有许多用于错误的枚举，例如：

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

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

对于每个枚举，我希望将描述存储在列表中，以便我能够做到这样的事情：

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

如果我使用多键字典或元组，它会起作用吗？任何显示如何执行此操作的示例？

我认为这对你有用，

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();
        }

Answer 2

您可以使用枚举full name string作为密钥。

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);
}

元组或多键字典？
