What is the opposite of BitConverter.To String(byte[]) ?

If I run the following code:

Byte[] bytes = System.Text.Enc oding.ASCII.Get Bytes("test");
return BitConverter.To String(bytes);

I get the string "74-65-73-74" back. My question is, what is the
easiest way to convert the string back to "test"?

Can it be done without breaking the string and using a loop, etc.? I
have tried many methods, but can't find a way without using a loop. It
seems silly that the framework can go one direction but not the other.

Any help please?

System.Text.Enc oding.ASCII.Get String(bytes);

i think that's what you're looking for.

I don't think so - that certainly doesn't do the reverse of
BitConverter.To String.

For me, BitConverter.To String is really for debug purposes, to easily
see the values in a byte array. That's why (I believe) there's no
reverse method.

System.Text.En coding.ASCII.Ge tString(bytes);

Thanks but this is not correct; this will give me a string of length 11
whereas I am looking for the original string of length 4. This is
because GetString() does not *decode* the hex values in the bytes.

So, I am still looking for a 1-step solution...

Greg,

I believe Jon is correct with his statement:

This will just give you a nice human readable representation of the bytes.

System.Text.Enc oding.ASCII.Get Bytes(string)
System.Text.Enc oding.ASCII.Get String(bytes)
would be complimentary functions dealing with the underlying data.

Just like MyObject.ToStri ng almost certainly would not give you a String from
which you could create an identical copy of your Object.

Looking at the language spec, I can't find a statement about the byte order for value types, such as int, float, etc. Are they guaranteed to be little-endian or big- endian? I know that, on a little-endian machine, the byte order is little-endian. But what if I run C# on a big- endian machine, say, using Mono? Does the C# language (or IL) make any guarantees as to the byte order?
