CType is used for when you want to
Cast an object of a Type into a different Type in VB.NET
In C# it's much easier. If you want to cast something into something else then you would just use:
-
Integer i;
-
i = 5;
-
-
Double j;
-
j = (Double) i;
This syntax cannot be used in VB.NET (probably because it uses brackets for so many things...arrays, functions etc) So, in VB.NET you either use the CType method or the DirectCast method to cast between object types:
-
Dim i As Integer
-
i = 5
-
-
Dim j As Double = Ctype(i, Double)
All the information you need on the CType method and any other .NET controls can be found in the
MSDN Library. There are multiple articles on the
CType Function there. I recommend bookmarking the MSDN Library and using it as your primary resource when developing in .NET.
