It is clear that the FileUpload components, which can be found on the Standard toolbar of Visual Studio 2005 allows uploading files to the remote site, but does not cover all the expectations desired or at least not mine.
So it is interesting to know how we can attack a specific server and an FTP to copy the desired file to the remote location to stay.
To do this:
Step 1: In general declarations establish that the class will use.
C#
using System.Net;
VB.NET
Imports System.Net
Step 2: Create a button in the Click event and write the following code in C# or VB.NET:
C#
private static void wc_UploadFTP(string ftpServerPath, string filename, string username, string password)
{
WebClient ClientFtp = new WebClient() ;
ClientFtp.Credentials = new NetworkCredential(username, password);
ClientFtp.UploadFile(ftpServerPath + "/" + new FileInfo(filename).Name, "STOR", filename);
}
VB.NET
Private Shared Sub wc_UploadFTP(ByVal ftpServerPath As String, ByVal filename As String, ByVal username As String, ByVal password As String) Dim ClientFtp As New WebClient() ClientFtp.Credentials = New NetworkCredential(username, password) ClientFtp.UploadFile((ftpServerPath & "/") + New FileInfo(filename).Name, "STOR", filename) End Sub
