Merging dictionaries in C#

Question

What\'s the best way to merge 2 or more dictionaries (Dictionary) in C#? (3.0 features like LINQ are fine).

I\'m thinking of a method signa

Answer 1

How about adding a params overload?

Also, you should type them as IDictionary for maximum flexibility.

public static IDictionary Merge(IEnumerable> dictionaries)
{
    // ...
}

public static IDictionary Merge(params IDictionary[] dictionaries)
{
    return Merge((IEnumerable) dictionaries);
}
