Can I check if an object is comparable to some other type?

I'd like to write some code like this:

if (obj.IsComparableTo(integer))
    Console.Write("successed");

Is this possible? If not, is there an a开发者_StackOverflow中文版lternative way of determining this?

Depending on what you mean by comparable, maybe:

var comparable = obj as IComparable<int>;
if(comparable != null) Console.Write("successed");

However, this only accounts for the interface, which would be rare. Most implicit conversions will be harder to check for. If you add more context, maybe a more appropriate solution will be easier to spot.

You object has to implement the interface IComparable<int>

public class Foo : IComparable<int>
{
}

It is not possible to compare two different types of objects unless they implement the IComparable interface.

i've found it :

        public bool isComparable<t>(object o)
        {
            try
            {
                object r = (t)o;
            }
            catch
            {
                return false;
            }
            return true;
        }

to use it:

if (isComparable<int>(32).ToString())
    Console.WriteLine("success");
else
    Console.WriteLine("fail");
