请问 如何读取.txt文件中的数据
请问 如何读取.txt文件中的数据 --------------------编程问答-------------------- 下面的示例从 FileStream 读取内容，并将其写入到另一个 FileStream。--------------------编程问答-------------------- 可以使用FileStream类，BAIDU一下很多的 --------------------编程问答-------------------- StreamReader读取
using System;
using System.IO;
class Test
{
public static void Main()
{
// Specify a file to read from and to create.
string pathSource = @"c:\tests\source.txt";
string pathNew = @"c:\tests\newfile.txt";
try
{
using (FileStream fsSource = new FileStream(pathSource,
FileMode.Open, FileAccess.Read))
{
// Read the source file into a byte array.
byte[] bytes = new byte[fsSource.Length];
int numBytesToRead = (int)fsSource.Length;
int numBytesRead = 0;
while (numBytesToRead > 0)
{
// Read may return anything from 0 to numBytesToRead.
int n = fsSource.Read(bytes, numBytesRead, numBytesToRead);
// Break when the end of the file is reached.
if (n == 0)
break;
numBytesRead += n;
numBytesToRead -= n;
}
numBytesToRead = bytes.Length;
// Write the byte array to the other FileStream.
using (FileStream fsNew = new FileStream(pathNew,
FileMode.Create, FileAccess.Write))
{
fsNew.Write(bytes, 0, numBytesToRead);
}
}
}
catch (FileNotFoundException ioEx)
{
Console.WriteLine(ioEx.Message);
}
}
}

推荐使用这种方法，考虑很全面 --------------------编程问答--------------------
不错 --------------------编程问答-------------------- 二楼的就行！！ --------------------编程问答--------------------
数据流读取 --------------------编程问答-------------------- File.ReadAllText() --------------------编程问答--------------------
嗯，找到对应的内容后，再处理，如果要再写入到文本里边，就用streamwriter
补充：.NET技术 , C#
