converting an array to a string

[Guest]

Hi,

How do I convert an array to a string ?
What I did was convert a string to an array, after some manipulation, I want
to pass the value back to a string.

char[] setchecked;
setchecked = strchecked.ToCharArray();
/////
I want to convert array setchecked[] back to a string n pass the value to
string strchecked.
or should i just:

strchecked = "";
foreach (char c in setchecked)
{ strchecked += c; }


TIA.
Andrew.

in VB.Net you can just cast an array of characters to a string

dim strChecked as string = cstr(setChecked);

In C#, you use the .Net method (though you could do that in VB.Net also),
which is rather plainly:

string strChecked = new string(setchecked);

doh!

Andrew,

In .Net strings are immutable, meaning they can't be changed. This means
that each iteration in your loop allocates new memory If you were to
take an approach like that I'd suggest you look into
System.Text.StringBuilder. That being said, check out the System.String
constructors, specifically System.String(Char[]).

So to answer your question try
strChecked = new String(setChecked);

HTH,

string myString = string.Concat(setchecked);

or if you wanted a separator between each char instance use

string.Join and pass it your separator and array to join
