Is there anyway to handy convert a dictionary to String?

Question

I found the default implemtation of ToString in the dictionary is not what I want. I would like to have {key=value, ***}.

Any handy way to get it?

Answer 1

How about an extension-method such as:

public static string MyToString
      (this IDictionary dictionary)
{
    if (dictionary == null)
        throw new ArgumentNullException("dictionary");

    var items = from kvp in dictionary
                select kvp.Key + "=" + kvp.Value;

    return "{" + string.Join(",", items) + "}";
}

Example:

var dict = new Dictionary
{
    {4, "a"},
    {5, "b"}
};

Console.WriteLine(dict.MyToString());

Output:

{4=a,5=b}
