選擇文件並將其上傳到特定文件夾

Question

我需要將一個選定的文件上傳到特定的文件夾。 我有以下代碼：

using System.IO;

namespace FTP_UPLOAD
{
    public partial class FTPUPLOAD : Form
    {
        public FTPUPLOAD()
        {
            InitializeComponent();
        }

        private void Button1_Click(object sender, EventArgs e)
        {
            var fileContent = string.Empty;
            var filePath = string.Empty;

            using (OpenFileDialog openFileDialog = new OpenFileDialog())
            {
                openFileDialog.InitialDirectory = "c:\\";
                openFileDialog.Filter = "zip files (*.zip)|*.zip";
                openFileDialog.FilterIndex = 2;
                openFileDialog.RestoreDirectory = true;

                if (openFileDialog.ShowDialog() == DialogResult.OK)
                {
                    //Get the path of specified file
                    filePath = openFileDialog.FileName;

                    //Read the contents of the file into a stream
                    var fileStream = openFileDialog.OpenFile();
                    {
                    }
                }
            }
            MessageBox.Show(fileContent, "File Content at path: " + filePath, MessageBoxButtons.OK);
        }
    }
}

我需要定義文件將被上傳到的位置（例如c：\\ ftp）。 該過程完成之后，我想向用戶顯示該文件所在的完整路徑，例如（filename = file.zip），而不是：ftp.mysite / file.zip

Answer 1

要復制文件，可以使用：

File.Copy(openFileDialog.FileName, "c:\\ftp\" + openFileDialog.SafeFileName,true);

Answer 2

獲取要保存的文件的路徑后，需要使用SaveFileDialog類。 using System.IO;添加using System.IO; 使用FileInfo類。

private void SaveFile(string filePath)
{
  FileInfo file = new FileInfo(filePath);

  using (SaveFileDialog saveFileDialog = new SaveFileDialog())
  {
    saveFileDialog.FileName = filePath;
    if( saveFileDialog.ShowDialog() == DialogResult.OK)
    {
      MessageBox.Show("Your file was saved at " + saveFileDialog.FileName);
    }                
  }
}
