get unique random number in vb.net

To generate a unique random number in VB.NET, you can use the Random class. Here's an example code snippet:

Dim random As New Random()
Dim randomNumber As Integer = random.Next()

In this code, we create an instance of the Random class and then use the Next() method to generate a random number. The Next() method returns a random integer.

Please note that if you want to generate a random number within a specific range, you can use the Next(minValue, maxValue) overload of the Next() method. For example, to generate a random number between 1 and 100, you can modify the code as follows:

Dim random As New Random()
Dim randomNumber As Integer = random.Next(1, 101)

In this case, the Next() method will generate a random number between 1 (inclusive) and 101 (exclusive).

I hope this helps!
