Accepted answer
the IP to which you want to send file, should be able to receive it, you cannot simply send file to any PC by just specifying its IP address.

the PC also should have some server or FTP or share drive where you can post your file.

public void upload()
{
string local = @"C:\temp";
string[] dir = Directory.GetFiles(local, "*.txt");
string filename;
foreach (var files in dir)
{
filename = files.Substring(8, files.Length - 8);

//here files gives complete file path including file name as C:\temp\file1.txt
//here dns is ip of server

//calling method
uploadfiles(filename, files,dns);

//working code- to above question i posted

public void uploadfiles(string fileName,string ipAddress)

string filepath=@"C:\temp";

//code to upload files within network

string dns = "\\\\" +ipAddress;
#region NetworkCommunicationLogic

//create a Share folder in Server in which you want to place files

string Share = @"\Share\";
string serverpath = dns+Share;

WebClient client = new WebClient();
string username = @"RDP Username";

string uri = serverpath + fileName;
NetworkCredential nc = new NetworkCredential(username, pass);

Uri ServerPath1 = new Uri(uri);
client.Credentials = nc;
byte[] arrReturn = client.UploadFile(ServerPath1, filepath);

Console.WriteLine("uploaded file :" + fileName);
