无法写入流程的输入

Question

我试图制作一个C＃函数，从MySQL服务器进行数据库转储。您可能知道，MySQL要求输入如下密码：

所以这就是我所做的：

success: function(msg){
    alert( "Data Saved: " + msg );


},
  error: function(XMLHttpRequest, textStatus, errorThrown) {
     alert("some error");
  }

当我执行此功能时，进程启动并等待用户写入密码，但public static bool BackupDatabase(string filename) { try { string mysqldumpdir = @"C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqldump.exe"; string user = "root"; string password = "root"; string databases= "hrsmarttest7"; ProcessStartInfo startInfo = new ProcessStartInfo { FileName = mysqldumpdir, RedirectStandardInput = true, Arguments = string.Format("--user {0} --password --databases {1} --result-file=\"{2}\"", user, databases, filename), UseShellExecute = false, CreateNoWindow = true }; var mysqldump = new Process { StartInfo = startInfo, EnableRaisingEvents = true }; mysqldump.Start(); System.Threading.Thread.Sleep(3000); mysqldump.StandardInput.AutoFlush = true; mysqldump.StandardInput.Write(password+"\n"); // this doesn't do the job !!! mysqldump.WaitForExit(); mysqldump.Close(); return true; } catch (Exception e) { //RecordException(e); return false; } } 没有写入密码，我必须终止程序以结束我的程序。

请帮忙。
