将文件作为缓冲区和bytearray放置不产生相同的哈希（xxhash）

我有一个 c＃脚本在字节数组中读取文件，并使用 xxhash c＃算法（非限制性哈希）类似：

 string p = "C:\\Users\\abc\\Documents\\bow.png";
 x = hash(File.ReadAllBytes(p), 10);

  private uint hash(byte[] data , int length, uint seed=0)
        {
           return  xxHash32.ComputeHash(data, length, seed);
        }

我想使用 expressjs 服务器中产生相同的哈希。 /package/xxhash“ rel =“ nofollow noreferrer”> xxhash js js中的库，但是我没有相同的哈希。这就是我在做的事情：

var XXHash = require('xxhash');
var fs = require('fs');

function getByteArray(filePath){
  let fileData = fs.readFileSync(filePath).toString('hex');
  let result = []
  for (var i = 0; i < fileData.length; i+=2)
    result.push('0x'+fileData[i]+''+fileData[i+1])
  return result;
}

file = Buffer.from(getByteArray( __dirname + "/Files/nfts/bow.png" ))
const uint32array = new Uint32Array(file);
var result = XXHash.hash(uint32array, 0);

我想问题是在C＃脚本中，我使用的是字节数组，但是在Nodejs中，我使用了 buffer 。您知道如何解决吗？

I have a C# script that reads a file in byte array and hashes it in 32 bits using xxhash c# algorithm (non-cryptographically hash) like this :

 string p = "C:\\Users\\abc\\Documents\\bow.png";
 x = hash(File.ReadAllBytes(p), 10);

  private uint hash(byte[] data , int length, uint seed=0)
        {
           return  xxHash32.ComputeHash(data, length, seed);
        }

and i want to produce the same hash in my expressjs server using xxhash JS library in js however I don't get the same hash. this is what I'm doing:

var XXHash = require('xxhash');
var fs = require('fs');

function getByteArray(filePath){
  let fileData = fs.readFileSync(filePath).toString('hex');
  let result = []
  for (var i = 0; i < fileData.length; i+=2)
    result.push('0x'+fileData[i]+''+fileData[i+1])
  return result;
}

file = Buffer.from(getByteArray( __dirname + "/Files/nfts/bow.png" ))
const uint32array = new Uint32Array(file);
var result = XXHash.hash(uint32array, 0);

I guess the problem is that in the c# script I'm using a byte array but in the nodejs I'm using a buffer. do you have any idea how to get around that ?
