Generic method how to use variables

Question

Hi,

I wonder how to assign values in a generic method :

Calls :

this.FormaterZones<trelEmplacement>(donnees);
this.FormaterZones<trelSpecification>(info);

Method that not wokring :

    private void FormaterZones<T>(T infos)
    {
        if (typeof(T) == typeof(trelEmplacement))
        {
            infos.emplacementDescriptionComplete = infos.emplacementDescriptionComplete.PremierMotLettreMajuscule();
        }
        else
        {
            if (typeof(T) == typeof(trelSpecification))
            {
                infos.specificationDescriptionComplete = infos.emplacementDescriptionComplete.PremierMotLettreMajuscule();
            }
        }

    }

public class trelSpecification
{
    [Key]
    public Guid trelSpecificationsId { get; set; }

    public int positionLigne { get; set; }

    [StringLength(1000)]
    public string? specificationDescriptionCompleteFr { get; set; }

    [StringLength(1000)]
    public string? specificationDescriptionCompleteEn { get; set; }

    [StringLength(1000)]
    public string? specificationDescriptionCompleteXy { get; set; }

}

Any suggestion? Thank you

@prof cegep, Welcome to Microsoft Q&A, you could try to use Convert.ChangeType method to cast generic type parameter to a specific type.

Here is a code example you could refer to.

 internal class Program
    {
        static void Main(string[] args)
        {
            trelEmplacement tr1=new trelEmplacement();

            trelSpecification tr2 = new trelSpecification();
            Program p=new Program();
            p.FormaterZones(tr1);
            p.FormaterZones(tr2);
            Console.WriteLine(tr1.emplacementDescriptionComplete);
            Console.WriteLine(tr2.specificationDescriptionComplete);
        }
        private void FormaterZones<T>(T infos)
        {
            if (typeof(T) == typeof(trelEmplacement))
            {
                trelEmplacement tr= (trelEmplacement)Convert.ChangeType(infos, typeof(trelEmplacement));
                tr.emplacementDescriptionComplete = "success";
               
            }
            else
            {
                if (typeof(T) == typeof(trelSpecification))
                {
                    trelSpecification tr= (trelSpecification)Convert.ChangeType(infos, typeof(trelSpecification));
                    tr.specificationDescriptionComplete = "failed";
               
                }
            }

        }
    }

    public class trelEmplacement
    {
        public string emplacementDescriptionComplete { get; set; }
    }

    public class trelSpecification
    {

        public string specificationDescriptionComplete { get; set; }

    }

Tested result:

Best Regards,

Jack
