Not that I am aware of. If you are using VB.NET you can use the VB compatability function StrConv: Dim properCase As String = StrConv("this is the day", VbStrConv.ProperCase)However, this is rather bad programming practice, since StrConv is not supported by the CLR. Not only that, but it cannot be used from C#.
If you want to do it the proper way, you'll need to do it manually, I think.
