i have array of objects that's are strings.
i need to convert it to array of string before sending to method.

is there a way to convert ? (short way..)

Re: is there way to convert array of objects to array of strings ?

You didn't really give enough detail to get a definite answer, but if it is
an actual array of strings, just typecast it.

For example (C#):

public void SomeFunctionOrOther (object[] actuallyAnArrayOfStrings)
{
string[] stringArray = (string[]) actuallyAnArrayOfStrings;
// followed by code that does something with it.
}


If you use VB you could try the CType() function

No. Not a short way. You'd have to create a string array, iterate
through the object array, and populate your new string with
myojbect[i].ToString()

Re: is there way to convert array of objects to array of strings ?

Roni,

\\\C#
object[] a = {"hello", "how", "are", "you"};
string[] b = new string[a.Length];
a.CopyTo(b, 0);
///

\\\VBNet
Dim a() As Object = {"hello", "how", "are", "you"}
Dim b(a.Length - 1) As String
a.CopyTo(b, 0)
///

I hope this helps,

Cor

I get a specified cast invalid

object[] myobjarray = new object[5];

for(int i=0;i<5;i++)

{

myobjarray[i] = (object)i.ToString();

}

string[] mystrarray = (string[])myobjarray;

for(int i=0;i<5;i++)

{

Console.WriteLine(mystrarray[i]);

}

Console.ReadLine();

Yes, there you've got an object array which happens to contain strings,
rather than a string array. You can't cast an object array to a string
array, despite all the contained objects being strings. (Just think
what would happen if you set myobjarray[i] = new object() afterwards.)

You can use Array.Copy though:

using System;

class Test
{
static void Main()
{
object[] myobjarray = new object[5];
for(int i=0;i<5;i++)
{
myobjarray[i] = (object)i.ToString();
}

string[] mystrarray = new string[myobjarray.Length];
Array.Copy(myobjarray, mystrarray, myobjarray.Length);

foreach (string x in mystrarray)
{
Console.WriteLine (x);
}
}
}

Right, I was replying to what appeared to be faulty code

I was replying because the post above mine claimed something
I thought wouldn't work would.
