Visual Basic .Net has two versions of OpenTextFileReader()
, as listed below:
Microsoft.VisualBasic.FileIO.FileSystem.OpenTextFileReader(String) As System.IO.StreamReader
Microsoft.VisualBasic.MyServices.FileSystemProxy.OpenTextFileReader(String) As System.IO.StreamReader
Are there any differences between the two? If so, what are they?
Also please discuss any pros & cons that may be relevant. For instance, calling from FileSystem
vs FileSystemProxy
.
I see one is Shared
but the other is not. I understand this means one applies to the base class, and the other to instances, but I'm not sure if/how that might affect the differences between them.
Based on the reference source here, Microsoft.VisualBasic.MyServices.FileSystemProxy.OpenTextFileReader(String)
is nothing more than a trampoline:
Public Function OpenTextFileReader(ByVal file As String) As IO.StreamReader
Return Microsoft.VisualBasic.FileIO.FileSystem.OpenTextFileReader(file)
End Function
I suspect it's there to facilitate the ergonomic My
namespace.
