将字节数组转换为字符串的最佳方法是什么?

I need to read [100]byte to transfer a bunch of string data.

Because not all of the strings are precisely 100 characters long, the remaining part of the byte array are padded with 0s.

If I tansfer [100]byte to string by: string(byteArray[:]), the tailing 0s are displayed as ^@^@s.

In C the string will terminate upon 0, so I wonder what's the best way of smartly transfer a byte array to string in Golang.

    methods that read data into byte slices return the number of bytes read. You should save that number and then use it to create your string. n being the number of bytes read, your code would look like this:

    s := string(byteArray[:n])
    

    If for some reason you don't have n, you could use the bytes package to find it, assuming your input doesn't have a null character in it.

    n := bytes.Index(byteArray, []byte{0})
    

    Or as icza pointed out, you can use the code below:

    n := bytes.IndexByte(byteArray, 0)
