Ahoj,
mám takový problém: nahrávám fotky z lokálního počítače na server, kde jsou uloženy webovky. Pokud pustím tento kód:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.IO;
namespace Pokus_nahravani
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Application.Exit();
}
private void Form1_Load(object sender, EventArgs e)
{
FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create("ftp://www.zs-dukelska.strakonice.eu/nahravani/pokus.jpg");
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential("uz_jmeno", "heslo");
request.UsePassive = true;
request.UseBinary = true;
request.KeepAlive = false;
request.Proxy = null;
FileStream stream = File.OpenRead(@"C:\pokus.jpg");
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
stream.Close();
Stream reqStream = request.GetRequestStream();
reqStream.Write(buffer, 0, buffer.Length);
reqStream.Close();
}
}
}
nahraje se vše správně a program skončí, aniž by vyhodil nějakou chybu.
Pokud ale pustím tento kód:

}
tak to vyhodí chybu na tomto řádku:
Stream reqStream = request.GetRequestStream();
Vyhodí to chybu, že se stala při nahrávání neočekávaná chyba.
Nutno podotknout, že mi z domova jdou oba programy, ale ze školy, pro kterou to dělám, mi jde jen ten první.
Už se s tím trápím docela dlouho, tak budu hrozně vděčnej, když na to někdo z vás přijde. Předem velké díky....:)
Pro pořádek ještě přidávám Designer pro druhý program:
