How to Convert a byte array into an int array?
提问by user1166981
How to Convert a byte array into an int array? I have a byte array holding 144 items and the ways I have tried are quite inefficient due to my inexperience. I am sorry if this has been answered before, but I couldn't find a good answer anywhere.
如何将字节数组转换为 int 数组？我有一个包含 144 个项目的字节数组，由于我的经验不足，我尝试的方法效率很低。如果之前已经回答过这个问题，我很抱歉，但我在任何地方都找不到好的答案。

Simple:
简单的：
//Where yourBytes is an initialized byte array.
int[] bytesAsInts = yourBytes.Select(x => (int)x).ToArray();
Make sure you include System.Linqwith a using declaration:
确保包含System.Linqusing 声明：
using System.Linq;
And if LINQ isn't your thing, you can use this instead:
如果 LINQ 不是你的东西，你可以用它来代替：
int[] bytesAsInts = Array.ConvertAll(yourBytes, c => (int)c);

I known this is an old post, but if you were looking in the first place to get an array of integers packed in a byte array (and it could be considering your array byte of 144 elements), this is a way to do it:
我知道这是一篇旧帖子，但是如果您首先要获取一个字节数组中的整数数组（并且可能会考虑您的 144 个元素的数组字节），这是一种方法：
var size = bytes.Count() / sizeof (int);
var ints = new int[size];
for (var index = 0; index < size; index++)
{
ints[index] = BitConverter.ToInt32(bytes, index * sizeof (int));
}
Note: take care of the endianness if needed. (And in most case it will)
注意：如果需要，请注意字节序。（并且在大多数情况下会）

Now It's Simple like follows,
现在很简单，如下所示，
int[] result = Array.ConvertAll(bytesArray, Convert.ToInt32);
