It would help if you'd give a bit of context - what's in your object[]?
What do you want to get in your char[]? What's the overall purpose
here?

Here is my code ( i want to get result from query that have FOR XML
AUTO ):
OleDbDataReader reader= cmd.ExecuteReader();

reader.Read();
object[] arObj = new object[reader.FieldCount];
int i = reader.GetValues(arObj);

Ah, I see. So, have you looked at what's inside arObj? What are the
values? Are they strings? I suspect they are, but I wouldn't like to
say for sure - just have a look.

OK, well at this point you now have an object array containing all the column
values of that row of the DataReader.

Are you saying you now need to convert each object in the array to type
char[]?
e.g.
char[] chAr=(char[])arObj[0];

?

I see in arObj[0],arObj[1]... is a number maybe char code. And my goal
is convert arObj to a string. Or how i can to get data from query that
have "FOR XML AUTO" ?
Thanks.
