How can we use SFTP in C# to transfer file to another location ?

Hi All,

I have 3 windows based Servers A,B and C. I will be creating a DLL using C# and put this DLL on Server B. Here one scheduler will be work.
When scheduler starts it will fetch a file from Server A through SFTP protocol and transfer on Server C through FTP protocol.

Please help me how can I solve this issue in dot net..

A<-->B(Scheduler will DLL)<--> C

Thanks in Advance.
