在文件读取的时候这样获取到要读取的文件里的数据的行数啊？
请指教！
谢谢……

filestream fs=new filestream("xxx.txt",filemodel.open);

streamreader sr=new streamreader(fs);

string line=sr.readline();

int rows=0;

while(!string.isnotnullorempty)
{
 rows++;
}

consoule.write(rows);

using System;
using System.Collections.Generic;
using System.Text;
using  ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            FileStream fs = new FileStream("xxx.txt", FileMode.Open);

            StreamReader sr = new StreamReader(fs);
            int rows = 0;

            string line = sr.ReadLine();

            while (line != null)
            {
                rows++;
                line = sr.ReadLine();
            }


            Console.WriteLine(rows.ToString());

            Console.Read();
        }
    }
}
