If i understand you correctly, there is a possible way in reflection to change the attribute value of a instance at runtime.. checkout the sample code

        AttributeCollection ac  = TypeDescriptor.GetAttributes(yourObj);

        foreach (var att in ac)
        {
            //DataEntityAttribute  -- ur attribute class name
            DataEntityAttribute da = att as DataEntityAttribute ;
            Console.WriteLine(da.field1);  //initially it shows MESSAGE_STAGING
            da.field1= "Test_Message_Staging";  
         }


         //Check the changed value
        AttributeCollection acc = TypeDescriptor.GetAttributes(yourObj);

        foreach (var att in ac)
        {
            DataEntityAttribute da = att as DataEntityAttribute ;
            Console.WriteLine(da.field1); //now it shows Test_Message_Staging
        }
