我需要上传一个选定的文件到一个特定的文件夹。我有以下代码:

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);
        }
    }
}

我需要定义文件上传到哪里(比如c:\ftp)。完成该过程后,我想向用户显示该文件所在位置的完整路径,例如(filename=file.zip)而不是:ftp.mysite/file.zip要复制该文件,可以使用:

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

要复制文件,可以使用:

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

获取要保存的文件的路径后,需要使用SaveFileDialog类。使用System.IO添加
使用FileInfo类

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);
    }                
  }
}

    }                
  }
}

那你有什么问题?您得到了什么?您期望得到什么?我可以选择该文件,但我需要将其复制到该文件夹(c:\ftp)。完成后,显示该文件的路径。那么您的问题是什么?您得到了什么?您期望得到什么?我可以选择该文件,但我需要将其复制到该文件夹(c:\ftp)。完成后,显示该文件的路径。请确认哪个答案对您有帮助。请确认哪个答案对您有帮助。
