The WinSCP .NET assembly (winscpnet.dll) is a .NET wrapper around WinSCP's scripting interface that allows your code to connect to a remote machine and manipulate remote files over SFTP, FTP, WebDAV and SCP sessions from .NET languages, such as C#, VB.NET, and others, or from environments supporting .NET, such as PowerShell and SQL Server Integration Services (SSIS).

The WinSCP .NET assembly winscpnet.dll is a .NET wrapper around WinSCP's scripting interface that allows your code to connect to a remote machine and manipulate remote files over SFTP, FTP, WebDAV and SCP sessions from .NET languages, such as C#, VB.NET, and others, or from environments supporting .NET, such as PowerShell and SQL Server Integration Services (SSIS).

For details see:

The assembly is also exposed to COM, and as such it can be used from variety of other programming languages and development environments--e.g., WSH-hosted active scripting languages like JScript and VBScript, Visual Basic for Applications (VBA), Perl, and Python.

For details see:

The library is primarily intended for advanced automation tasks that require conditional processing, loops or other control structures for which the basic scripting interface is too limited. The library is not a general purpose file transfer library. It particularly lacks support for interactive processing and as such it is not well suited for use in GUI applications.
