Hello pedestrian via DotNetMonster.c om,

Create an array of the characters you want to fill from. Then check out
the Ssytem.Random class.

-Boo

Let's say I declares an array of string (of size 1000), how to fill
every elements of it with random characters?

In addition to the other comments:

How long do you want each string?

How random do you want each string?

To get random "password" keys (WEP Keys) I will use
RNGCryptoServic eProvider.GetNo nZeroBytes:

http://msdn2.microsoft.com/en-us/lib...zerobytes.aspx

Followed by BitConverter.To String:

If you don't want or need a cryptographical ly strong sequence of values, you
could use System.Random in a loop. Just remember to create the new
System.Random object outside the loop then call its Next method inside the
loop:

http://msdn2.microsoft.com/en-us/lib...em.Random.aspx

I would use the Random.Next method that accepted a range of values...
passing in Char code points

Thanks for replying... Mr Jay
I would like to use the strings to insert values to database columns...
such as FirstName, LastName, Address etc.. columns...
