Default Generation of alphanumeric random characters

Hi Friends,

I want to generate 25 distinct randam alphanumeric characters in one ASP.NET page. I am using following code
private int GenerateRandomNumber(){
Thread.Sleep( 1 );
Random r = new Random(DateTime.Now.Millisecond);
int a=0;
while (!( (a>=48 && a<=57) ||(a>=65 && a<=90) ||(a>=97 && a<=122)))
a = r.Next(123);
intNumber += 1;
return a;}

But this function always produces same 25 characters. Any idea?

What about replacing

a = r.Next(123);

a=(new Random(DateTime.Now.Millisecond)).Next(123);
