c# – 如何加快从字符串中删除文本的方法？

我想尽快做到这一点.

有没有办法加快以下代码？

using System;

namespace TestRemoveFast
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] tests = {
            "{http://company.com/Services/Types}ModifiedAt","{http://company.com/Services/Types}CreatedAt"
                             };

            foreach (var test in tests)
            {
                Console.WriteLine(Clean(test));
            }

            Console.ReadLine();
        }

        static string Clean(string line)
        {
            int pos = line.IndexOf('}');
            if (pos > 0)
                return line.Substring(pos + 1,line.Length - pos - 1);
            else
                return line;
        }
    }
}
