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.
Simple:
//Where yourBytes is an initialized byte array.
int[] bytesAsInts = yourBytes.Select(x => (int)x).ToArray();
Make sure you include System.Linq
with a using declaration:
using System.Linq;
And if LINQ isn't your thing, you can use this instead:
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:
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)
现在很简单,如下所示,
int[] result = Array.ConvertAll(bytesArray, Convert.ToInt32);
Use Buffer.BlockCopy instead of Array.ConvertAll.
ref Converting an int[] to byte[] in C#
byte[] bytes = new byte[] { 0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, 0x8 };
int[] ints= Array.ConvertAll(bytes, Convert.ToInt32);
will return ints[]={0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, 0x8},
not return ints[]={0x04030201,0x08070605}
should use Buffer.BlockCopy(bytes, 0, ints, 0, bytes.Length);
