对路径“”“”的访问被拒绝 C#

Question

I'm logged in as an admin on my PC, but this shows up

here's my code:

string file = "C:\\Users\\owner\\Documents\\backup.sql";
using (MySqlConnection conn = new MySqlConnection(constring))
{
    using (MySqlCommand cmd = new MySqlCommand())
    {
        using (MySqlBackup mb = new MySqlBackup(cmd))
        {
            try
            {
                cmd.Connection = conn;
                conn.Open();
                mb.ExportToFile(file);
                conn.Close();
            }catch(Exception ex){
                MessageBox.Show(ex.Message);
            }
        }
    }
}

PS: I already have a connection string at the very top of my code.

Answer 1

There is a possibility, that you are getting the error because the file doesn't exist. I could be wrong, but I looked into the source and it doesn't check whether the file already exists.

Answer 2

hey ? are you using mysqlbackup.dll as reference ? if yes maybe this can help .. just go to the folder you want to be the storage of your saved files

Private Sub BackupDatabaseToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BackupDatabaseToolStripMenuItem.Click

  'using mysqlbackup.dll as reference

  Dim cmd As MySqlCommand = New MySqlCommand

  cmd.Connection = connect()

  Dim filepth As String = "C:\Users\IT\Documents\DB_Backup.sql"

  Dim mb As MySqlBackup = New MySqlBackup(cmd)

  mb.ExportToFile(filepth)

  MsgBox("Database Backup Successfully !", MsgBoxStyle.Information, "Project")

  disconnect()
End Sub
