在C＃中的FileStream的StreamReader问题 [英] FileStream StreamReader problem in C#

问题描述

我测试类的FileStream和StreamReader的是如何工作的togheter。通过一个控制台应用程序。
我试图去在一个文件中读取行并打印在控制台上。

I'm testing how the classes FileStream and StreamReader work togheter. Via a Console application. I'm trying to go in a file and read the lines and print them on the console.

我已经能够用whil​​e循环做到这一点，但我想用foreach循环来试试吧。

I've been able to do it with a while-loop, but I want to try it with a foreach loop.

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

namespace testing
{
    public class Program
    {
        public static void Main(string[] args)
        {
            string file = @"C:\Temp\New Folder\New Text Document.txt";
            using(FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read))
            {
                using(StreamReader sr = new StreamReader(fs))
                {
                    foreach(string line in file)
                    {
                        Console.WriteLine(line);
                    }
                }
            }
        }
    }
}

我不断收到此错误是：无法将类型'字符'到'字符串'

The error I keep getting for this is: Cannot convert type 'char' to 'string'

while循环，它不工作，看起来是这样的：

The while loop, which does work, looks like this:

while((line = sr.ReadLine()) != null)
{
    Console.WriteLine(line);
}

我可能真的俯瞰基本的东西，但我无法看到它。

I'm probably overlooking something really basic, but I can't see it.

推荐答案

要阅读新建文本文档.txt的所有行：

To read all lines in New Text Document.txt:

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

namespace testing
{
    public class Program
    {
        public static void Main(string[] args)
        {
            string file = @"C:\Temp\New Folder\New Text Document.txt";
            using(FileStream fs = new FileStream(file, FileMode.Open, FileAccess.Read))
            {                    
                using(StreamReader sr = new StreamReader(fs))
                {
                    while(!sr.EndOfStream)
                    {
                       Console.WriteLine(sr.ReadLine());
                    }
                }
            }
        }
    }
}
