从位置读取文件 [英] Read file from position

问题描述

FileStream infile = new FileStream(@"C:\Users\John\Desktop\ProjectNew\nov.txt",     FileMode.Open, FileAccess.Read);
        int position = x.Length;
        infile.Seek(position, SeekOrigin.Begin);

但Seek方法返回数字。如何从字符串中读取infile文件？

But Seek method returns number. How to read the file 'infile' from position to end in a string?

推荐答案

假设你想从位置100开始阅读...使用（FileStream fs = new FileStream（@file.txt）来使用

Is this what you're after? Assuming you wanted to start reading from position 100...

       using (FileStream fs = new FileStream(@"file.txt", FileMode.Open, FileAccess.Read))
        {
            fs.Seek(100, SeekOrigin.Begin);

            byte[] b = new byte[fs.Length - 100];
            fs.Read(b, 0, (int)(fs.Length - 100));

            string s = System.Text.Encoding.UTF8.GetString(b);
        }
