Access Bitlocker recovery info from Active Directory

Question

I am finding links to recover bitlocker passwords from active directory using vbscript, but I would like to do this using my c# program.

I have found some information on this, but nothing has been successful so far. Can anyone help out and correct the code, or point me in the direction of solving this?

here is the latest code that I have found and tested, but it doesn't work

class BitlockerModel
{
    public string RecoveryGuid { get; set; }
    public string RecoveryPassword { get; set; }
    public string Date { get; set; }
    public string Time { get; set; }

    public BitlockerModel()
    {
        RecoveryGuid = string.Empty;
        RecoveryPassword = string.Empty;
        Date = string.Empty;
        Time = string.Empty;
    }
}

private void btnBitlockerSearch_Click(object sender, EventArgs e)
    {
        try
        {
            var computerName = txtBitlockerSearch.Text;
            if ((string.IsNullOrEmpty(computerName)))
            {
                MessageBox.Show(@"Computername can't be empty");
                return;
            }
            var bitlockerObject = new BitlockerLookup();
            var result = bitlockerObject.GetBitlockerInfo(computerName).ToList();

            foreach (var items in result)
            {
                lsBitlockerInformation.Items.Add(string.Format("Date: {0}", items.Date));
                lsBitlockerInformation.Items.Add(string.Format("Time: {0}", items.Time));
                lsBitlockerInformation.Items.Add(string.Format("RecoveryGUID: {0}", items.RecoveryGuid));
                lsBitlockerInformation.Items.Add(string.Format("Recovery Password: {0}", items.RecoveryPassword));
                lsBitlockerInformation.Items.Add(Environment.NewLine);
            }
        }
        catch
        {

弄清楚了，尽管我必须建立一个模型来保存响应并使用管理员帐户运行应用程序，但是开始的代码运行良好。
