element vertex 303943 

property float x 

property float y 

property float z 

property uchar red 

property uchar green 

property uchar blue 

end_header 

1.955 1.647 -1.359 182 185 182 

0.87 1.532 -1.453 152 160 153 

0.843 1.548 -1.484 153 161 154

試試這個

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.IO; 

namespace ConsoleApplication93 
{ 
    class Program 
    { 
     const string FILENAME = @"c:\temp\test.txt"; 
     static void Main(string[] args) 
     { 
      List<List<double>> data = new List<List<double>>(); 
      StreamReader reader = new StreamReader(FILENAME); 
      string inputLine = ""; 
      Boolean endHeader = false; 
      while ((inputLine = reader.ReadLine()) != null) 
      { 
       inputLine = inputLine.Trim(); 
       if (inputLine.Length > 0) 
       { 
        if(endHeader) 
        { 
         List<double> newRow = inputLine.Split(new char[] { ' ', '\t' }, StringSplitOptions.RemoveEmptyEntries).Select(x => double.Parse(x)).ToList(); 
         data.Add(newRow); 
        } 
        else 
        { 
         if(inputLine.Contains("end_header")) 
         { 
          endHeader = true; 
         } 
        } 
       } 
      } 

     } 
    } 

}
