How do you convert multistring to/from C# string collection?

Question

Multistrings (double null-terminated string of null-separated strings) are common in the Windows API. What\'s a good method for converting a multistring returned from an API

Answer 1

This might be naïve, but how about:

static string[] MultiStringToArray(string multiString)
{
    return multiString.TrimEnd('\0').Split('\0');
}

Also - aren't you missing the final \0 (you state double-null-terminated) in StringArrayToMultiString? And it might be easier to call if the array was a params string[] array - something like:

    static string StringArrayToMultiString(params string[] values)
{
    if (values == null) throw new ArgumentNullException("values");
    StringBuilder multiString = new StringBuilder();

    foreach (string s in values)
    {
        multiString.Append(s);
        multiString.Append('\0');
    }
    return multiString.ToString();
}
