通过 C# 使用 Powershell 执行脚本

Question

我需要执行以下脚本： Get-MailboxDatabase -Status |选择服务器名称、名称、数据库大小

我尝试了一些使用 Powershell 和 Command 类的解决方案，但它们不起作用。 我收到的错误： 值参数不能为空。

我认为这会满足您的需求：

private string RunLocalExchangePowerShell(string script)
{
    // create the runspace and load the snapin
    RunspaceConfiguration rsConfig = RunspaceConfiguration.Create();
    PSSnapInException snapInException = null;
    Runspace runSpace = RunspaceFactory.CreateRunspace(rsConfig);
    runSpace.Open();
    rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.E2010", out snapInException);
    Pipeline pipeLine = runSpace.CreatePipeline();

    // load the script and convert the output to a string
    pipeLine.Commands.AddScript(script);
    pipeLine.Commands.Add("out-string");

    // get the results
    Collection<PSObject> results;
    results = pipeLine.Invoke();

    // loop through the results and build the output
    StringBuilder sb = new StringBuilder();
    foreach (PSObject obj in results)
    {
        sb.AppendLine(obj.ToString());
    }

    // close the pipeline and runspace
    pipeLine.Dispose();
    runSpace.Close();

    return sb.ToString();
}

示例用法：

Console.WriteLine(prog.RunLocalExchangePowerShell("Get-MailboxDatabase -Status | select ServerName,Name,DatabaseSize"));
