C# array to string

irishdude11

i have a byte array in C#. Is there a function to convert this to a string?
For example

buffer[0] = 2;
buffer[1] = 8;
buffer[2] = 3;

Is there a function that will convert that to the string '283'

I imagine you can do something along these lines. Set string1 = buffer[0]. Set string2 = buffer[1]. Then set string1 = string1 + string2. Then set string2 = buffer[2]. Then set string1 = string1 + string2. Repeat until the buffer is exhausted.

Should be possible to do a for loop for this if you can get the + operator to work as described in the above link.

A nice-looking way to do it with linq would be something like

byte[] buffer = new byte[] {2,8,3};
string n = String.Join("", buffer.Select(x => x.ToString()).ToArray());

or in .NET 4.0 just

byte[] buffer = new byte[] {2,8,3};
string n = String.Join("", buffer.Select(x => x.ToString()));

alternatively if buffer were really really big a StringBuilder would be more efficient:

byte[] buffer = new byte[] {1,2,3};
var sb = new StringBuilder();
foreach (var x in buffer) sb.Append(x);
string n = sb.ToString();

I'd do:

Encoding.ASCII.GetString(array);

Or replace ASCII with whatever target encoding you're working with.

[PHP]buffer[0] = 2;
buffer[1] = 8;
buffer[2] = 3;

Is there a function that will convert that to the string '283' [/PHP]

why do you want to do this ?

I think in .NET 4.0 you have string.Join(string, object[]), meaning you can just pass buffer directly in.
