Best approach is to use a named group:

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
        string xyz = "text/plain; charset=US-ASCII; name=\"anythingfile.txt\"";
        Match m = Regex.Match(xyz, "name=\"(?<name>[^\"]+)\"");
        Console.WriteLine(m.Groups["name"].Value);
        Console.ReadKey();
    }
}

Do you really need regex? Simple string operations may be enough:

var NameValue = xyz.Split(';')
                   .Select(x => x.Split('='))
                   .ToDictionary(y => y.First().Trim(), y => y.LastOrDefault());
