使用PowerShell讀取C＃中的Office 365組成員

Question

我試圖連接到Office 365組，並使用PowerShell通過C＃項目列出組的成員資格。

From this article，我已經決定我需要使用命令是

Get-UnifiedGroupLinks –Identity groupalias –LinkType Members 

這裏是我當前的代碼：

string connectionUri = "https://outlook.office365.com/powershell-liveid/"; 
SecureString secpassword = new SecureString(); 
foreach (char c in Password) 
{ 
    secpassword.AppendChar(c); 
} 
PSCredential credential = new PSCredential(UserName, secpassword); 

Runspace runspace = RunspaceFactory.CreateRunspace(); 
PSObject SessionHolder = null; 
using (PowerShell powershell = PowerShell.Create()) 
{ 
    PSCommand command = new PSCommand(); 
    command.AddCommand("New-PSSession"); 
    command.AddParameter("ConfigurationName", "Microsoft.Exchange"); 
    command.AddParameter("ConnectionUri", new Uri(connectionUri)); 
    command.AddParameter("Credential", credential); 
    command.AddParameter("Authentication", "Basic"); 
    powershell.Commands = command; 

    runspace.Open(); 
    powershell.Runspace = runspace; 
    Collection<System.Management.Automation.PSObject> result = powershell.Invoke(); 
    if (powershell.Streams.Error.Count > 0 || result.Count != 1) 
    { 
     throw new Exception("Fail to establish the connection"); 
    } 
    else 
     SessionHolder = result[0]; 
} 
using (PowerShell powershell = PowerShell.Create()) 
{ 
    PSCommand command = new PSCommand(); 
    // –Identity groupalias –LinkType Members 
    command = new PSCommand(); 
    command.AddCommand("Invoke-Command"); 
    command.AddParameter("ScriptBlock", System.Management.Automation.ScriptBlock.Create("Get-UnifiedGroupLinks")); 
    command.AddParameter("Session", SessionHolder); 
    command.AddParameter("Identity", groupAddress); 
    command.AddParameter("LinkType", "Members"); 
    powershell.Commands = command; 
    powershell.Runspace = runspace; 

    Collection<PSObject> PSOutput = powershell.Invoke(); 
    // loop through each output object item 
    foreach (PSObject outputItem in PSOutput) 
    { 

    } 
} 

上面使用的變量，未顯示的聲明： 「用戶名」， 「Password」，「groupAddress」

我能夠建立與服務的連接，但是當我嘗試獲取組成員時我收到錯誤「找不到與參數名'身份'相匹配的參數」

我不知道如何繼續解決我的代碼。我已經在Identity參數中嘗試了組電子郵件，羣組別名和羣組顯示名稱。也許我還有其他錯誤？

我使用下面庫在Visual Studio 2017年在Windows 10的機器上：

using System.Management.Automation; 
using System.Management.Automation.Runspaces;

我發現一些代碼，使事情的工作......這減緩下來，所以我不知道是否有更好的方法，但這裏是我的更新代碼：

string connectionUri = "https://outlook.office365.com/powershell-liveid/"; 
SecureString secpassword = new SecureString(); 
foreach (char c in Password) 
{ 
    secpassword.AppendChar(c); 
} 
PSCredential credential = new PSCredential(UserName, secpassword); 

Runspace runspace = RunspaceFactory.CreateRunspace(); 
PSObject SessionHolder = null; 
using (PowerShell powershell = PowerShell.Create()) 
{ 
    string connectionUri = "https://outlook.office365.com/powershell-liveid/"; 
    SecureString secpassword = new SecureString(); 
    foreach (char c in Password) 
    { 
     secpassword.AppendChar(c); 
    } 
    PSCredential credential = new PSCredential(UserName, secpassword); 
    PSCommand command = new PSCommand(); 
    command.AddCommand("New-PSSession"); 
    command.AddParameter("ConfigurationName", "Microsoft.Exchange"); 
    command.AddParameter("ConnectionUri", new Uri(connectionUri)); 
    command.AddParameter("Credential", credential); 
    command.AddParameter("Authentication", "Basic"); 
    powershell.Commands = command; 

    runspace.Open(); 
    powershell.Runspace = runspace; 
    Collection<System.Management.Automation.PSObject> result = powershell.Invoke(); 
    if (powershell.Streams.Error.Count > 0 || result.Count != 1) 
     throw new Exception("Fail to establish the connection"); 
    else 
     SessionHolder = result[0]; 

    PSCommand ImportSession = new PSCommand(); 
    ImportSession.AddCommand("Import-PSSession"); 
    ImportSession.AddParameter("Session", SessionHolder); 
    powershell.Commands = ImportSession; 
    powershell.Invoke(); 

    PSCommand GrabGroup = new PSCommand(); 
    GrabGroup.AddCommand("Get-UnifiedGroupLinks"); 
    GrabGroup.AddParameter("Identity", GroupAddress); 
    GrabGroup.AddParameter("LinkType", "Members"); 
    powershell.Commands = GrabGroup; 
    Collection<PSObject> PSOutput_GroupMembers = powershell.Invoke(); 
    foreach (PSObject outputItem in PSOutput_GroupMembers) 
    { 
     //Process Members 
    } 
} 

關鍵似乎是我需要導入會話才能開始使用它。

通常我得到這個錯誤時，我傳遞變量與一些額外的字符。檢查變量是如何傳遞的，如果它只是「電子郵件」或者是否包含其他信息，如@ {「email」}。在Powershell中很常見。

希望能夠流露出一些光芒。因爲命令很簡單：

Get-UnifiedGroupLinks -Identity [name] -LinkType members
