术语 'New-CsOnlineSession' 未被识别为 cmdlet 的名称

The term 'New-CsOnlineSession' is not recognized as the name of a cmdlet

我正在尝试 运行 来自 c# 的强大 shell 脚本。 当仅 运行 启用强大的 shell 脚本时,它 运行 成功。但是,在尝试 运行 来自 c# 的相同脚本时。我收到错误 "The term 'New-CsOnlineSession' is not recognized as the name of a cmdlet"

代码如下:

          public static void GetLyncUsers(string userName, string password)
        {
            using (PowerShell powerShellInstance = PowerShell.Create())
            {

                var script = string.Format("$Username =\"{0}\"\n" +
                                           "$Password =\"{1}\"\n" +
                                           "$secpasswd = ConvertTo-SecureString $Password -AsPlainText -Force\n" +
                                           "$cred = new-Object System.Management.Automation.PSCredential ($Username  , $secpasswd)\n" +
                                           "$CSSession = New-CsOnlineSession -Credential $cred\n" +
                                           "Import-PSSession $CSSession -AllowClobber\n" +
                                           "Get-CsOnlineUser", userName, password);

                // use "AddScript" to add the contents of a script file to the end of the execution pipeline.
                // use "AddCommand" to add individual commands/cmdlets to the end of the execution pipeline.

                powerShellInstance.AddScript(script);


                // use "AddParameter" to add a single parameter to the last command/script on the pipeline.


                // invoke execution on the pipeline (collecting output)
                Collection<PSObject> psOutput = powerShellInstance.Invoke();

                // check the other output streams (for example, the error stream)
                if (powerShellInstance.Streams.Error.Count > 0)
                {
                    // I am getting this error 
                  //The term 'New-CsOnlineSession' is not recognized as the name of a cmdlet
                }
        }

有什么我遗漏的吗? powershell 总体上是新手

解决方案:

using (PowerShell powerShellInstance = PowerShell.Create())
{    
    // Import-Module lynconlineconnector
    powershellInstance.Commands
        .AddCommand("Import-Module")
        .AddArgument("lynconlineconnector");

// rest of your code ....

为什么?

当 运行 在 powershell v3 及更高版本中进行交互式会话时,主机会捕获 CommandNotFound,并在所有已知位置搜索每个模块。如果找到命令,它会自动加载模块,并正常进行。

当 运行 在 C# 中使用相同的脚本时,不会捕获 CommandNotFound 异常,因此会出现错误。

我运行遇到了同样的问题。您必须按照 Technet

中的说明安装 Lync/Skype For Business Online Connector

The setup program copies the Skype for Business Online Connector module (and the New-CsOnlineSession cmdlet) to your local computer.
