C#如何分割多个空格分隔的字符串？

using System;
using System.Text;
using System.Text.RegularExpressions;

namespace test
{
	class Program
	{
		public static void Main(string[] args)
		{
			string pp="1063792.4  2764405.825  5.464413E-05     -1.780467E-04";
			string[] mm=Regex.Split(pp,"\\s+",RegexOptions.IgnoreCase);
			for (int i=0;i<mm.Length;i++)
			{
				Console.Write(mm[i]+'\n');
			}

			// TODO: Implement Functionality Here

			Console.Write("Press any key to continue . . . ");
			Console.ReadKey(true);
		}
	}
}
