AnySafe

Determines if the collection contains any elements. If the argument is null, false will be returned. This is useful when you don't know in advance whether the collection will be null or not.

Source

public static bool AnySafe<T>(this IEnumerable<T> collection)
{
    var result = false;

    if (collection!= null)
    {
        result = collection.Any();
    }

    return result;
}

Short version:

public static bool AnySafe<T>(this IEnumerable<T> collection)
{
    return (collection != null) ? collection.Any() : false;
}

Example

List<string> names = null;
var result = names.AnySafe(); //false, names is null

names = new List<string>();
result = names.AnySafe(); //false, no items in collection

names.Add("Item1");
result = names.AnySafe(); //true
