如何在VB.net中进行备份和恢复mysql数据库

Question

如何在vb.net中备份和恢复数据库mysql我使用xampp。但是当备份过程开始时，加载他的生活进度条。

这是我的编码：

Private Sub btnBackup_Click(ByVal sender As System.Object, _ByVal e As System.EventArgs) Handles btnBackup.Click

Dim file As String 

sfd.Filter = "SQL Dump File (*.sql)|*.sql|All files (*.*)|*.*"

sfd.FileName= "Database Backup "  + DateTime.Now.ToString("yyyy-MM-dd HH-mm-ss") + ".sql"

If sfd.ShowDialog = DialogResult.OK Then

file = sfd.FileName

Dim myProcess As New Process()

myProcess.StartInfo.FileName = "cmd.exe"

myProcess.StartInfo.UseShellExecute = False

myProcess.StartInfo.WorkingDirectory ="C:\xampp/mysql/bin"

myProcess.StartInfo.RedirectStandardInput = True

myProcess.StartInfo.RedirectStandardOutput = True

myProcess.Start()

Dim myStreamWriter As StreamWriter= myProcess.StandardInput

Dim mystreamreader As StreamReader = myProcess.StandardOutput

myStreamWriter.WriteLine("mysqldump -u root --password=1 _  -h 127.0.0.1 ""minimart"" > """   file   """ ")

myStreamWriter.Close()

myProcess.WaitForExit()

myProcess.Close()

MsgBox("Backup Created Successfully!", MsgBoxStyle.Information, "Backup")

EndIf

End Sub

所以我想在带有进度条
