我正在创建多个条件语句来查看不同的 PowerShell 命令。我遇到的一个问题是get-hotfix我想使用，where-object但当我调用 PSCommand 时，我得到了这个错误

System.Management.Automation.RemoteException: '无法绑定参数 'FilterScript'。无法将类型为“System.String”的“$_.InstalledOn -gt $StartTimeGenerated”值转换为类型为“System.Management.Automation.ScriptBlock”。'

这是我的代码：

if(command == "get-hotfix")
{
    _HotFixViewAll = ReadInfo("ViewAllHotFix");
    _hotfixInterval = Convert.ToDecimal(ReadInfo("HotFixInterval"));

    if (_HotFixViewAll != "Y")
    {
        DateTime DateNow = DateTime.Now;
        TimeSpan datetimeInterval = TimeSpan.FromDays((double)_hotfixInterval);
        DateTime StartTimeGenerated = DateNow.Subtract(datetimeInterval);

        var filterScript = ScriptBlock.Create("$_.InstalledOn -gt $StartTimeGenerated");
        var whereCommand = new Command("Where-Object");
        whereCommand.Parameters.Add("FilterScript", filterScript);
        whereCommand.Parameters.Add("ArgumentList", StartTimeGenerated);
        pipeline.Commands.Add(whereCommand);
    }

    var sortCommand = new Command("Sort-Object");
    sortCommand.Parameters.Add("Property", "InstalledOn"); 
    sortCommand.Parameters.Add("Descending");
    pipeline.Commands.Add(sortCommand);
}

我该如何解决这个问题？

全面方法

                using (var runspace = RunspaceFactory.CreateRunspace(connectioninfo))
                {
                    runspace.Open();
                    using (var pipeline = runspace.CreatePipeline())
                    {
                        // Command to execute remotely
                        var psCommand = new Command(command);
                        pipeline.Commands.Add(psCommand);

                        if(command == "get-hotfix")
                        {
                            _HotFixViewAll = ReadInfo("ViewAllHotFix");
                            _hotfixInterval = Convert.ToDecimal(ReadInfo("HotFixInterval"));

                            if (_HotFixViewAll != "Y")
                            {
                                DateTime DateNow = DateTime.Now;
                                TimeSpan datetimeInterval = TimeSpan.FromDays((double)_hotfixInterval);
                                DateTime StartTimeGenerated = DateNow.Subtract(datetimeInterval);

                                var filterScript = ScriptBlock.Create("$_.InstalledOn -gt $StartTimeGenerated");
                                var whereCommand = new Command("Where-Object");
                                whereCommand.Parameters.Add("FilterScript", filterScript);
                                whereCommand.Parameters.Add("ArgumentList", StartTimeGenerated);
                                pipeline.Commands.Add(whereCommand);
                            }

                            var sortCommand = new Command("Sort-Object");
                            sortCommand.Parameters.Add("Property", "InstalledOn"); // Sort by InstalledOn column
                            sortCommand.Parameters.Add("Descending"); // Sort in descending order
                            pipeline.Commands.Add(sortCommand);
                        }
                        else if (command == "Get-ADDomainController")
                        {
                            psCommand.Parameters.Add("Server", machinename); // Add the target parameter
                        }
                        else if(command == "Get-ADReplicationPartnerMetadata")
                        {
                            psCommand.Parameters.Add("Server", machinename); // Add the target parameter
                        }

                        // Execute the command
                        var results = pipeline.Invoke();
