如何将byteArray写入特定路径

Question

I currently have a method which is taking a picture and saving it.. Once saved I call this method to encrypt the file from a string path but im not sure how to save it.. I wanted to do

string path = @"C:/somePath"

File.WriteAllBytes(path);

but that doesnt work obv. So how do I properly save a bytearray?

string key = GetUniqueKey(32);
byte[] encKey = Encoding.UTF8.GetBytes(key);
byte[] imgBytes = File.ReadAllBytes(path);
byte[] ebytes = encrypt.AESEncrypt(imgBytes, encKey);
File.WriteAllBytes();

Answer 1

If you actually check the parameters it's asking for, you need to provide the bytes as well as the path.

So:

string path = @"C:/somePath/somefile.png"
string key = GetUniqueKey(32);
byte[] encKey = Encoding.UTF8.GetBytes(key);
byte[] imgBytes = File.ReadAllBytes(path);
byte[] ebytes = encrypt.AESEncrypt(imgBytes, encKey);
File.WriteAllBytes(path, ebytes);

Answer 2

方法的签名是：

File.WriteAllBytes(string path, byte[] bytes)
