C# generic list <T> how to get the type of T?

I have a list variable and I want to get the type of that list and cast a second variable to that type. For clarity I added the code below.

Currently I have the following:

return _ValueList.Any<FieldType>(x => x.Equals((FieldType)fieldValueObject));

I want to do something like this:

Type valueType = _ValueList.GetType();

return _ValueList.Any<FieldType>(x => x.Equals((valueType)fieldValueObject));

Any help will be appreciated.

Update:

A invalid cast exception is thrown when fieldValueObject is of type Int16 and I try to cast it to Int32.

Update 2:

I used the following solution:

        if (fieldValueObject.GetType() == typeof(Int16))
        {
            fieldValueObject = Convert.ToInt32(fieldValueObject);
        }
        return _ValueList.Any<FieldType>(x => x.Equals(fieldValueObject));

It is not pretty but it works.

Answer 1

public bool ContainsAny<T>(List<T> valueList, T fieldValueObject)
{
    return valueList.Any(x => x.Equals(fieldValueObject));
}

or

public bool ContainsAny<T>(List<T> valueList, object fieldValueObject)
{
    return valueList.Any(x => x.Equals((T)fieldValueObject));
}

Note that the second can throw an InvalidCastException.
