int到字节然后返回int不会返回相同的值

我必须通过网络发送整数值数组。它们只能以字节数组字节[]发送。

但是问题是，当另一个设备接收到的字节时 - 转换回int时不会给出相同的值？

下面的代码及其输出是我面临的问题

int x = GetUniqueID();
Debug.Log("Int value is: " + x.ToString());
byte b = (byte)x;
Debug.Log("Converted to byte is: " + b.ToString());
int y = (int)b;
Debug.Log("Converted back to int is: " + y.ToString());

private int GetUniqueID()
    {
        int x;
        x = Random.Range(0, 1000);

        return x;
    }

，这是上述代码的控制台输出（运行两次）：

为什么在int转换为byte之后，为什么未返回原始值？

原文

I have to send an array of integer value over the network. They can only be sent as a byte array byte[].

But the problem is that when that byte that is received by the other device - when converted back to int does not give the same value?

Below code and its output is the problem that I am facing

int x = GetUniqueID();
Debug.Log("Int value is: " + x.ToString());
byte b = (byte)x;
Debug.Log("Converted to byte is: " + b.ToString());
int y = (int)b;
Debug.Log("Converted back to int is: " + y.ToString());

private int GetUniqueID()
    {
        int x;
        x = Random.Range(0, 1000);

        return x;
    }

And here is the console output of the above code (run twice):

Why is the original value not returned after the int is converted to byte?

您将int（32位或4个字节）施放为一个单个字节 byte 。这会导致您的价值被截断，这就是为什么您看到它在示例中从344减少到88的原因。

而是尝试使用 bitconverrer class将int转换为byte []

byte[] b = BitConverter.GetBytes(x)

You are casting an int, which is 32 bits or 4 bytes, into a byte which is a single byte. This causes your value to be truncated, which is why you are seeing it reduce from 344 to 88 in your example.

Instead try using the BitConverter class to convert an int into a byte[]
