Change Name of Datamember dynamically in C#

Question

I want Name of Datamember to be displayed dynamically

public class SampleDTO
{

      [DataMember]
      public int Time1 { get; set; }
    
      [DataMember]
      public int Time2 { get; set; }
}

For example,

Time1 value entered by user = 20, Name of Time1 property should be displayed like “Case > 20 (mins)”

If Time1 value entered by user = 15, Name of Time1 property should be displayed like “Case > 15 (mins)”

How can I do this? Can anyone help me on this.
