C# Convert Byte Array with nulls to string
All,
I have a question about converting byte arrays with nulls to C# string. Here is an example of my byte array that I would like to convert to string. I expect to get a string with value SHKV
[0]: 83
[1]: 0
[2]: 72
[3]: 0
[4]: 75
[5]: 0
[6开发者_如何学Go]: 86
[7]: 0
How can I do it in C# ?
Thanks, MK
You really need to know the original encoding in order to convert it successfully.
I suspect that in this case the encoding is probably UTF-16, which you can convert as follows:
byte[] yourByteArray = new byte[] { 83, 0, 72, 0, 75, 0, 86, 0 };
string yourString = Encoding.Unicode.GetString(yourByteArray));
Console.WriteLine(yourString); // SHKV
That looks like little-endian UTF-16, so:
string s = Encoding.Unicode.GetString(data);
Are you guaranteed to always see this encoding of the strings (char, null, char, null, etc.)? If so, you can simply use the Unicode string encoder to decode it:
Byte[] contents = new Byte[] {83, 0, 72, 0, 75, 0, 86, 0};
Console.WriteLine(System.Text.Encoding.Unicode.GetString(contents));
Assuming ASCII bytes, you can do use LINQ:
new string(bytes.Where(b => b != 0).Select(b => (char)b).ToArray());
However, I suspect that you're trying to hack away Unicode data.
DON'T.
Instead, use the Encoding
class.
string str = new ASCIIEncoding().GetString(bytes.Where(i => i != 0).ToArray());
Also you can use UnicodeEncoding
, UTF32Encoding
, UTF7Encoding
or UTF8Encoding
Using Linq syntax:
var chars =
from b in byteArray
where b != 0
select (char) b;
string result = new String(chars.ToArray());
Though you are better off selecting the right encoding instead, as others have suggested.
byte[] b = new byte[]{83,0,72,0,75,0,86,0};
System.Text.Encoding.Unicode.GetString(b);
