Get a random character from a string.

Question

I need to get a random character out of a string.

Thanks.

Answer 1

Get a random number 0 through the length of the string. Ask the string for the nth character.

Some things to try Googling:

• CharAt
• Index
• Rand
• Random

Of course, add "VB.Net" to your search queries. Use what you know, find what you don't.

Answer 2

Dim str As String = "This is an example String"
Dim rnd As New Random(Date.Now.Millisecond)
Dim index As Int32 = rnd.Next(0, str.Length - 1)
Dim rndChar As Char = str(index)
