Casting object[] -> string[]

[AC]

I've put some strings into a stack, and now I want to convert the stack to an string based array. Here's what I'm trying to do (this returns a cast error)

string[] results = (string)resultStack.ToArray();

I've tried casting it as a string, an array of strings... no luck. ideas?

AC,

There are different ways to do this, One of them may be.

//define new string array with the size of object array
string [] strArray= new string [objArray.Length];

//loop it out and fill the values
for(int j=0;j<strArray.Length;j++)
{
strArray[j] = new string(objArray[j].ToString().ToCharArray());
}

Thanks for the reply... I am looking for an explicit cast option. This is
one option (brute force) I was hoping to avoid.

string[] results = (string[])resultStack.ToArray(typeof(string));

Makes sense when yo usee the answer. Thanks John. Wasn't aware .ToArray()
took an optional parm on what to case the array as.

Not a cast, really: the parameter tells ToArray what sort of array to
create. Shakir's solution

//define new string array with the size of object array
string [] strArray= new string [objArray.Length];

//loop it out and fill the values
for(int j=0;j<strArray.Length;j++)
{
strArray[j] = (string)objArray[j];
}

is more or less what ToArray() does internally, with the expected result if
some member of the array isn't a string (i.e. an exception).
