C#比较两个文本文件的内容是否相等

1.引用:using System.IO;

2.代码:

class Program

{

static void Main(string[] args)

{

string filePath1 = "F:\\测试文件\\11.txt";

string filePath2 = "F:\\测试文件\\22.txt";

using (HashAlgorithm hash = HashAlgorithm.Create())

{

using (FileStream file1 = new FileStream(filePath1, FileMode.Open), file2 = new FileStream(filePath2, FileMode.Open))

{

byte[] hashByte1 = hash.ComputeHash(file1);//哈希算法根据文本得到哈希码的字节数组

byte[] hashByte2 = hash.ComputeHash(file2);

string str1 = BitConverter.ToString(hashByte1);//将字节数组装换为字符串

string str2 = BitConverter.ToString(hashByte2);

if (str1 == str2)

{

Console.WriteLine("相同");

}

else

{

Console.WriteLine("不同");

}

}

Console.ReadKey();

}

}

}
