Question

Is there a way to check if a variable is value type of reference type?

Imagine:

private object GetSomething<T>(params T[] values) 
{
    foreach (var value in values)
    {
        bool is ValueType; // Check if 'value' is a value type or reference type
    }
}

Answer 1

bool isValueType = typeof(T).IsValueType;

Job done… it doesn’t matter if any of the values is null, and it works even for an empty array.
