在ASP.NET網站上顯示Powershell對象的值
[英]Display values from powershell objects on asp.net site
問題描述
我被要求創建幾個與asp.net網站一起使用的PowerShell腳本。 但是，asp.net站點和C＃一起對我來說是全新的領域。
搜索www我發現一些博客展示了如何運行.ps1腳本以及如何在文本框中顯示輸出。 這工作得很好，而且我還能夠將參數傳遞給測試腳本。
現在，我想對輸出進行更多格式化，以獲得更好，更“復雜”的UI。 我在Sapiens PowerShell Studio中創建了一個快速且骯臟的WPF表單，該表單如下所示：
它正在顯示以下WmiObject的值，這些值是我從舊的SCCM測試服務器中$SCCMinfo = Get-WmiObject -Namespace 'root\\SMS' -Class 'SMS_ProviderLocation' -ComputerName "6.6.5.5.4.4"
這是具有兩列的布局表。 左邊是帶有“靜態”文本的標簽，右邊是帶有$ SCCMinfo對象的實際值的標簽（例如： $labelGenusVal.Text = $SCCMinfo.__GENUS ）
如何使用asp.net表單實現相同目的？ 我所能找到的就是如何在一個元素中顯示完整的輸出。
編輯：
我可以通過在.ps1中為所需的每個值實現寫輸出，然后在aspx.cs中對結果進行索引。
但是我發現這是一個非常丑陋的解決方案。 有沒有直接的方法可以從PowerShell腳本中檢索變量及其值？ 我還嘗試了shell.Runspace.SessionStateProxy.PSVariable.GetValue("VarName"); 和shell.Runspace.SessionStateProxy.GetVariable("VarName"); 但他們總是返回null。
這是我當前的解決方案：
.aspx.cs
using System;
using System.Management.Automation;
namespace WPS_Test2
{
public partial class SCCM_info : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void ExecuteCode_Click(object sender, EventArgs e)
{
// Clean the Result TextBox
//ResultBox.Text = string.Empty;
// Initialize PowerShell engine
var shell = PowerShell.Create();
string pathToWPS = @"C:\Users\sudo\Desktop\WPS_projects\WPS_Test2\WPS_Test2\zzz_wps_scripts\SCCM_info.ps1";
// Add the script to the PowerShell object
shell.AddCommand(pathToWPS);
// Add some arguments / params
shell.AddParameter("sccm_server", SCCM_server.Text);
// Execute the script
var results = shell.Invoke();
LabelSelectedSCCMsrv.Text = "selected SCCM server: " + SCCM_server.Text;
var SCCMiGenus = results[0].ToString();
labelGenusVal.Text = SCCMiGenus;
var SCCMiClass = results[1].ToString();
labelClassVal.Text = SCCMiClass;
var SCCMiSuperclass = results[2].ToString();
labelSuperclassVal.Text = SCCMiSuperclass;
var SCCMiDynasty = results[3].ToString();
labelDynastyVal.Text = SCCMiDynasty;
var SCCMiRelpath= results[4].ToString();
labelRelpathVal.Text = SCCMiRelpath;
var SCCMiPropertyCount = results[5].ToString();
labelPropertyCountVal.Text = SCCMiPropertyCount;
var SCCMiDerivation = results[6].ToString();
labelDerivationVal.Text = SCCMiDerivation;
var SCCMiServer = results[7].ToString();
labelServerVal.Text = SCCMiServer;
var SCCMiNamespace = results[8].ToString();
labelNamespaceVal.Text = SCCMiNamespace;
var SCCMiPath = results[9].ToString();
labelPathVal.Text = SCCMiPath;
var SCCMiMachine = results[10].ToString();
labelMachineVal.Text = SCCMiMachine;
var SCCMiNamespacePath = results[11].ToString();
labelNamespacePathVal.Text = SCCMiNamespacePath;
var SCCMiProviderForLocalSite = results[12].ToString();
labelProviderForLocalSiteVal.Text = SCCMiProviderForLocalSite;
var SCCMiSiteCode = results[13].ToString();
labelSiteCodeVal.Text = SCCMiSiteCode;
var SCCMiPSComputerName = results[14].ToString();
labelPSComputerNameVal.Text = SCCMiPSComputerName;
}
}
}

我終於能夠實現一個適當的解決方案。 如果您知道如何的話，這很簡單。
我為標簽使用了與結果相同的ID。成員名稱並使用額外的if語句遍歷它們，以將其文本設置為適當的值（如果不為null）。 在.ps1中，我只是返回所需的var（在這種情況下，只有$SCCMinfo ）
如果有更好的解決方案，我歡迎您提出建議。 畢竟我還在學習。
全部在一起：
