Today i can upload files one by one each time a single file.
But now i want to upload some files togeather for example i select 5 files then it should upload the first file when finish then upload the second file ....untill the last one.
This is the code in form1:
using System;
using System.ComponentModel;
using System.Collections.Generic;
using System.Diagnostics;
using System.Text;
using System.Threading;
using System.Windows.Forms;
using System.Drawing;

public Form1()
{
InitializeComponent();
this.Select();
txtHost.Text = FtpAddress;
txtUsername.Text = UserName;
txtPassword.Text = Password;
txtHost.ForeColor = txtHost.WaterMarkForeColor;
txtUsername.ForeColor = txtUsername.WaterMarkForeColor;
txtPassword.ForeColor = txtPassword.WaterMarkForeColor;
txtDir.ForeColor = txtDir.WaterMarkForeColor;
txtUploadFile.ForeColor = txtUploadFile.WaterMarkForeColor;
txtHost.TextChanged += anyTextBox_TextChanged;
txtUploadFile.TextChanged += anyTextBox_TextChanged;
txtDir.TextChanged += anyTextBox_TextChanged;
anyTextBox_TextChanged(null, null);
if ((txtHost.Text == "") || (txtUploadFile.Text == ""))
{
btnUpload.Enabled = false;
txtHost.WaterMark = "Enter ftp valid address";
txtUploadFile.WaterMark = "Select a file to upload";
}
if (txtDir.Text == "")
{
checkBox1.Enabled = false;
txtDir.WaterMark = "Enter a sub directory name(optinal)";
}
if (txtUsername.Text == "")
{

this.Invalidate();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void btnBrowse_Click(object sender, EventArgs e)
{

try
{

}
catch { }
this.toolStripProgressBar1.Visible = true;
this.ftpProgress1.RunWorkerAsync(f);
this.btnUpload.Text = "Cancel";
}
}
private void ftpProgress1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.toolStripStatusLabel1.Text = e.UserState.ToString(); // the message will be something like: 45 Kb / 102.12 Mb
this.toolStripProgressBar1.Value = Math.Min(this.toolStripProgressBar1.Maximum, e.ProgressPercentage);
}
private void ftpProgress1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)

}
private void checkBox2_CheckedChanged(object sender, EventArgs e)
{
if (checkBox2.Checked)
{
txtPassword.PasswordChar = checkBox1.Checked ? * : \0;
}
else
{

}
}
}
}
Some information:
txtHost is a textBox for the ftp address.
txtUsername for username.
txtPassword for password.
txtDir for directory.
txtUploadFile for file.
All this are textBoxes.
I added this part:
if (txtDir.Text != null || txtDir.Text != "")
{
FtpProgress.d = new DirectoryInfo(txtDir.Text);
}
d is DirectoryInfo
Now the class of where im doing the uploading:

try

flist = d.GetFiles();
if (flist.GetLength(0) > 0)
{
foreach (FileInfo txf in flist)
{
string fn = txf.FullName;
BackgroundWorker bw = sender as BackgroundWorker;
f = e.Argument as FtpSettings;
string UploadPath = String.Format("{0}/{1}{2}", f.Host, f.TargetFolder == "" ? "" : f.TargetFolder + "/", Path.GetFileName(fn));//f.SourceFile));
if (!UploadPath.ToLower().StartsWith("ftp://"))
UploadPath = "ftp://" + UploadPath;
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(UploadPath);

catch (Exception ex)

}
}
}
using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
System.Diagnostics.Debug.WriteLine(String.Format("Upload File Complete, status {0}", response.StatusDescription));
}
}
}

}
}
public class FtpSettings
{
public string Host, Username, Password, TargetFolder, SourceFile;
public bool Passive;
public int Port = 21;
}
}
It was working fine fo single file but i changed/added this part:
In the top of the class:
public static DirectoryInfo d;
private FileInfo[] flist;
Then i added the part:
foreach (FileInfo txf in flist)
{
string fn = txf.FullName;
And instead f.SourceFile i changed it to fn.
But im getting exception:
The remote server returned an error: (550) File unavailable (e.g., file not found, no access).
And it did work before the changes for a sing file.
What i want it to do now is like before upload each time a single file using the backgrounworker and progressBar just like before my changes but this time when it finish to upload the first file go to the backgroundworker completed event show the Completed message just like for a single file and then move on automatic to the next file and so on untill the last file in FileInfo[] in the FtpProgress class.
If files(FileInfo[]) contain 1 file upload one single file. If it contain 121 files upload all the 121 files one by one.
How can i do it ? What do i need to change/add to my code ?
