Use text input by a user to reference/call the data in a variable VB.NET

Question

I want to be able to reference a variable by what the user enters: For example:

Dim str1 As String = "sherrifs"
Dim str2 As String = "cowboys"
Dim str3 As String = "aliens"
Dim strUserInput As String
    Console.WriteLine("Please enter a variable name: ")
    strUserInput = Console.ReadLine()

If the user enters str1 then the output should be sherrifs etc.. How would I go about doing this in vb.net? Thanks

The usual way, in a console mode app, to give a user a choice between 3 options is to let him enter a number between 1 and 3. — Hans Passant

Best way would be to keep your items in a Dictionary<string, string> object. Keep key as variableName, value as variableValue.

Dictionary<string, string> variableList = new Dictionary<string, string>()
variableList.Add("str1", "sherrifs")
variableList.Add("str2", "cowboys")
variableList.Add("str3", "aliens")

Dim strUserInput As String
Console.WriteLine("Please enter a variable name: ")
strUserInput = Console.ReadLine()

If variableList.ContainsKey(strUserInput) Then
   Console.WriteLine(variableList(strUserInput))
Else
   Console.WriteLine ("No luck")
