c# - Enum Display Name - Use variable? -

Can I do this? It does not seem so. Public enum option {[Display (name = string. Format ("{0} - {1}", "option one", MyClass.myVariable))] OptionOne = 1, [Display (Name = string format ("{0} - {1}", "option two", MyClass.myVariable))] OptionTwo = 2}

public anonymous option {[display ( Name = "Option 1")] OptionOn = 1, [Display (name = "Option2")] OptionTwo = 2}

 
 code> 

If not, So how do I create a display name for an enum variable?

It seems that no one is working with it:

If not, then How do I create a display name for an enum variable?

I can think of any type of map and extension method that can work like this:

  System use; Using System.Collections.Generic; Namespace Console Application 1 {Public Enum Fu {1 = 1, 2 = 2}, Public Static Class Extension-Method {Private Static Readonly Dictionary & lt; Enum, string & gt; S_EnumMap = New Dictionary & lt; Enum, string & gt; {{Foo.One, string.Format ("{0} - {1}", "option one", 1)}, {Foo.Two, string.Format ("{0} - {1}", "option Two ", 2)}}; Public Static String Converttoastring (this ANUUF) {Return S_Numem [EPF]; }} Internal category program {Private Static Zero Main (string [] ARG) {console. WrightLine (Foo.One.ConvertToString ()); Console.WriteLine (Foo.Two.ConvertToString ()); }}}  

The integers can be replaced by 1 and 2 example static variables, such as MyClass.myVariable . If you use this code, keep in mind that s_EnumMap will store those values ​​that the MyClass.myVariable variable was in when you first used the ExtensionMethods class (I.e. when steady fields of MyClass were being started). Therefore, modifying the code as follows:

  Public MyClass {public static int myVariable = 5; } Public Static Class ExtensionMathals {Private Static Readonly Dictionary & lt; Enum, string & gt; S_EnumMap = New Dictionary & lt; Enum, string & gt; {{Foo.One, string.Format ("{0} - {1}", "option one", MyClass.myVariable)}, {Foo.Two, string.Format ("{0} - {1}", "Option two", 2)}}; Public Static String Converttoastring (this ANUUF) {Return S_Numem [EPF]; }} Internal category program {Private Static Zero Main (string [] ARG) {console. WrightLine (Foo.One.ConvertToString ()); Console.WriteLine (Foo.Two.ConvertToString ()); MyClass.myVariable = 100; Console.WriteLine (Foo.One.ConvertToString ()); Console.WriteLine (Foo.Two.ConvertToString ()); }}  

The result will be:

option one - 5 options - two options - 2 options one - 5
option two - 2

After commenting outside the first two console. WriteLine , the output will be:

option one - 100 - option two - 2

So if you want to give feedback on the changes to the MyClass.myVariable , you will need to apply some arguments to update s_EnumMap, but Until I am about that goal I do not know much in whatever you are trying to achieve, I can not give a better answer.
