i set uniqueidentifier column in table,

NO need to use Multithreading Here..
..but however 10 crore unique number generation will take time..
to create fast we should make some modification in Table..like Table Partition..

string RandomNumber=RandamNumberGenerator();



public string RandamNumberGenerator()
{

var chars = "0123456789";
var random = new Random();

var result = new string(
Enumerable.Repeat(chars, 10)
.Select(s => s[random.Next(s.Length)])
.ToArray());
return result;
}

You can use Membership.GeneratePassword();

Syntax:
public static string GeneratePassword(
int length,
int numberOfNonAlphanumericCharacters
)

Example:

// Generate a new 12-character password with 1 non-alphanumeric character.
string password = Membership.GeneratePassword(12, 1);
