C#运行powershell命令如何传递字节数组

我试图从c#代码调用powershell命令，需要作为参数字节数组传递，但它转换为错误的格式。 C#代码：

实际上，powershell：

Set-UserPhoto -Identity:'hennadiy.lebedyev@itera.no' -Confirm:$False -PictureData:'255','216','255','224',...,'0','16'

Set-UserPhoto -Identity:'hennadiy.lebedyev@itera.no' -Confirm:$False -PictureData:(255,216,255,224,...,0,16)

所需的powershell：

Set-UserPhoto -Identity:'hennadiy.lebedyev@itera.no' -Confirm:$False -PictureData:'255','216','255','224',...,'0','16'

Set-UserPhoto -Identity:'hennadiy.lebedyev@itera.no' -Confirm:$False -PictureData:(255,216,255,224,...,0,16)

无法运行与函数AddScript powershell一起使用。

如果您的“Command”类相当于System.Management.Automation.PSCommand，则说明您的操作是正确的

下面是我用来执行此操作的代码：

const string connectionUri = "https://outlook.office365.com/powershell-liveid/?proxymethod=rps";
const string schemaUri = "http://schemas.microsoft.com/powershell/Microsoft.Exchange";

const string loginPassword = "password";
SecureString secpassword = new SecureString();
foreach (char c in loginPassword)
{
    secpassword.AppendChar(c);
}
PSCredential exchangeCredential = new PSCredential("demo@sample.com", secpassword);

WSManConnectionInfo connectionInfo = new WSManConnectionInfo(new Uri(connectionUri), schemaUri, exchangeCredential)
{
    MaximumConnectionRedirectionCount = 5,
    AuthenticationMechanism = AuthenticationMechanism.Basic
};

using (var remoteRunspace = RunspaceFactory.CreateRunspace(connectionInfo))
{
    remoteRunspace.Open();

    using (PowerShell powershell = PowerShell.Create())
    {
        powershell.Runspace = remoteRunspace;

        var command = new PSCommand()
            .AddCommand("Set-UserPhoto")
            .AddParameter("Identity", "user@sample.com")
            .AddParameter("PictureData", File.ReadAllBytes(@"C:\Test\MyProfilePictures\pic.jpg"))
            .AddParameter("Confirm", false);
        powershell.Commands = command;
        powershell.Invoke();
    }
}

？proxymethod=rps

希望您不要使用实际的powershell命令提供帮助。您可以加载一个文件，通过管道将其传输到命令，并使用管道对象作为参数。事实上，

Set UserPhoto

在流而不是字节缓冲区中也能正常工作，也许与您的问题正交，但为什么要使用C#调用powershell？您不能直接调用脚本正在使用的任何API，绕过所有powershell限制吗？
