How to get static properties from static class using reflection

Question

I've got a static class with static getters.

public static class Cars
{
   public static KeyValuePair<Guid, string> Acura
   {
       get { return new KeyValuePair<Guid, string>(new Guid("MMMMMMMM-509B-477A-ADB1-5CD014B41001"), "Acura"); }
   }
   public static KeyValuePair<Guid, string> AlfaRomeo
   {
      get { return new KeyValuePair<Guid, string>(new Guid("MMMMMMMM-509B-477A-ADB1-5CD014B41002"), "Alfa Romeo"); }
   }
   // etc.
}

I need to retrieve all the static properties from this static class and do something with each KeyValuePair. But the following throws a System.FormatException at runtime saying that it could not find recognizable digits

Type type = typeof(Cars);
foreach(var manufacturer in type.GetProperties())
{
    if(manufacturer.PropertyType == typeof(KeyValuePair<Guid, string>))
    {
        var v = manufacturer.GetValue(null, null); //this does not work
        // How to get the KeyValuePair<Guid, string>? 
    }
}

How to get each KeyValuePair?

UPDATE: Sorry.. the solution works perfectly, the problem is that GUID are not valuid Guids.. M is not hexadecimal character

Answer 1

This does not have to do anything with reflection or static properties. Within the getters of your properties there are exceptions thrown.

"MMMMMMMM-509B-477A-ADB1-5CD014B41001" and "MMMMMMMM-509B-477A-ADB1-5CD014B41002" are no valid Guid s. Create Guid s with valid values and the properties won't throw the exceptions.

Each of the digits in a Guid must be a hexadecimal digit (see here ).

new Guid("MMMMMMMM-509B-477A-ADB1-5CD014B41001")

will throw the exception, while for example

new Guid("00000000-509B-477A-ADB1-5CD014B41001")

won't.
