Type Conversion using functions
You can also use the classic Visual Basic keywords such as Val(), CStr(), CInt(), CBool(), and so on to perform data type conversions with the standard data types. However, the CType() function is a nice generic solution that works for all scenarios.
Example
Module Module1
Sub Main()
Dim TextString As String = "world"
Dim TextString2 As String = "111"
Dim Number As Integer
Dim Number2 As Integer
Number = Val(TextString) ' Number is now 0, because TextString contains no numeric information.
Number2 = Val(TextString2) ' Number is now 0, because TextString contains no numeric information.
Console.WriteLine(Number)
Console.WriteLine(Number2)
Console.ReadLine()
End Sub
End Module
Output
0
111
