我从各种来源混淆了以下查询，但无法使其工作，因此它只返回输出框中的选定字段。我需要用户通过网络输入路径，因此无法使用 addscript 命令。如果在 zip 过滤器之后删除 3 个命令，则脚本将返回 powershell 命令的输出。我添加了这三行，以为我可以选择它返回的字段。任何帮助将不胜感激。

        Result.Text = string.Empty;

        InitialSessionState iss = InitialSessionState.CreateDefault2();

        // Initialize PowerShell Engine
        var shell = PowerShell.Create(iss);

        // Add the command to the Powershell Object, then add the parameter from the text box with ID Input
        //The first one is the command we want to run with the input, so Get-ChildItem is all we need
        shell.Commands.AddCommand("Get-ChildItem").AddParameter("Path", Input.Text)
                                                  .AddParameter("Filter", "*.zip");
        shell.AddCommand("select-object");

            var results = shell.Invoke();

            // display results, with BaseObject converted to string

            if (results.Count > 0)
            {
                // We use a string builder ton create our result text
                var builder = new StringBuilder();

                foreach (var psObject in results)
                {
                    // Convert the Base Object to a string and append it to the string builder.
                    // Add \r\n for line breaks
                    builder.Append(psObject.BaseObject.ToString() + "\r\n");
                }

                // Encode the string in HTML (prevent security issue with 'dangerous' caracters like < >
                Result.Text = Server.HtmlEncode(builder.ToString());
            }
        }
        catch (ActionPreferenceStopException Error) { Result.Text = Error.Message; }
        catch (RuntimeException Error) { Result.Text = Error.Message; };
    }
}
}
