byte[] to hex string

Question

How do I convert a `byte[]` to a `string`? Every time I attempt it, I get System.Byte[] instead of the value. Also, how do I get the value in Hex instead of a decimal?

Accepted Answer

There is a built in method for this:

```
byte[] data = { 1, 2, 4, 8, 16, 32 };

string hex = BitConverter.ToString(data);
```

Result: 01-02-04-08-10-20

If you want it without the dashes, just remove them:

```
string hex = BitConverter.ToString(data).Replace("-", string.Empty);
```

Result: 010204081020

If you want a more compact representation, you can use Base64:

```
string base64 = Convert.ToBase64String(data);
```
