C# Is Type in list question

Basic c# question. In the sample bellow But the 'is' doesn't like the type variable. Any ideas there should be a simple answer.

    List<object> list = new List<object>();
    list.Add("one");
    list.Add(2);
    list.Add('3');

    Type desiredType = typeof(System.Int32);

    if 开发者_JAVA技巧(list.Any(w => w is desiredType))
    {
        //do something
    }

Try this:

List<object> list = new List<object>();
list.Add("one");
list.Add(2);
list.Add('3');

Type desiredType = typeof(System.Int32);

if (list.Any(w => w.GetType().IsAssignableFrom(desiredType)))
{
    //do something
}

Anyway: are you sure you want to create a list of objects?

w.GetType() == desiredType.

Why are you abusing generics like that?

You could use the Linq extension method OfType:

list.OfType<> will return an IEnumerable to any items of the specified type.

If I recall correctly you have to write w is System.Int32..

The delegate is expecting a type or a namespace, but you're supplying a type instance. Try this:

if (list.Any(w => w is Int32))
{
    //do something
}
