.NET与PowerShell集成开发指南

在现代软件开发中,.NET框架和C#语言为开发者提供了强大的工具和丰富的类库。与此同时,PowerShell作为一种强大的命令行脚本工具,也广泛应用于Windows系统的管理与自动化任务中。本文将介绍如何将.NET和C#与PowerShell进行集成,创建自定义的C#控件,并在PowerShell脚本中直接使用这些控件。

创建自定义C#控件

在Visual Studio中,可以通过创建“Windows Forms Control Library”类型的项目来开发自定义的Windows Forms控件。在本例中,将创建一个名为“PSMap”的控件,该控件将用于增强PowerShell的“New-PSDrive”命令的功能。

首先,需要定义控件的界面和功能。在C#中,可以使用Windows Forms Designer来设计控件的界面,并使用代码来实现其功能。以下是一个简单的示例代码,展示了如何创建一个包含多个下拉菜单和标签的控件:

namespace PSMap { partial class MapControl { private System.ComponentModel.IContainer components = null; protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } private void InitializeComponent() { this.DriveLetter = new System.Windows.Forms.ComboBox(); this.ServerName = new System.Windows.Forms.ComboBox(); this.ShareName = new System.Windows.Forms.ComboBox(); this.Credentials = new System.Windows.Forms.ComboBox(); this.lb_DriveLetter = new System.Windows.Forms.Label(); this.lb_ServerName = new System.Windows.Forms.Label(); this.lb_ShareName = new System.Windows.Forms.Label(); this.lb_Credentials = new System.Windows.Forms.Label(); this.lb_Title = new System.Windows.Forms.Label(); this.lb_justcode = new System.Windows.Forms.Label(); this.lb_About_PSMap = new System.Windows.Forms.Label(); this.PSProvider = new System.Windows.Forms.ComboBox(); this.lb_psprovider = new System.Windows.Forms.Label(); this.SuspendLayout(); // // DriveLetter // this.DriveLetter.FormattingEnabled = true; this.DriveLetter.Items.AddRange(new object[] { "HKLM", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z" }); this.DriveLetter.Location = new System.Drawing.Point(6, 54); this.DriveLetter.Name = "DriveLetter"; this.DriveLetter.Size = new System.Drawing.Size(96, 21); this.DriveLetter.TabIndex = 0; this.DriveLetter.SelectedIndexChanged += new System.EventHandler(this.DriveLetter_SelectedIndexChanged); // // ServerName // // ... (省略部分代码) } private System.Windows.Forms.ComboBox DriveLetter; private System.Windows.Forms.ComboBox ServerName; private System.Windows.Forms.ComboBox ShareName; private System.Windows.Forms.ComboBox Credentials; private System.Windows.Forms.Label lb_DriveLetter; private System.Windows.Forms.Label lb_ServerName; private System.Windows.Forms.Label lb_ShareName; private System.Windows.Forms.Label lb_Credentials; private System.Windows.Forms.Label lb_Title; private System.Windows.Forms.Label lb_justcode; private System.Windows.Forms.Label lb_About_PSMap; private System.Windows.Forms.ComboBox PSProvider; private System.Windows.Forms.Label lb_psprovider; } }

在上述代码中,定义了一个名为“MapControl”的部分类,其中包含了多个下拉菜单和标签。这些控件将用于收集用户输入的参数,以便在PowerShell脚本中创建新的PSDrive。

PowerShell中使用自定义控件

在PowerShell中,可以通过加载.NET程序集来使用自定义的C#控件。以下是一个示例脚本,展示了如何在PowerShell中加载并使用“PSMap”控件:

# 加载自定义控件 [Reflection.Assembly]::LoadFile('C:\PSMapDll-Deploy\PSMap.dll') [void] [System.Reflection.Assembly]::LoadWithPartialName("System.Drawing") [void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") # 设置主窗体 $objForm = New-Object System.Windows.Forms.Form $objForm.Text = "PSMapForm" $objForm.Size = New-Object System.Drawing.Size(600, 340) $objForm.StartPosition = "CenterScreen" # 添加自定义控件 $objCustom = New-Object PSMap.MapControl $objCustom.Location = New-Object System.Drawing.Size(0, 0) $objCustom.Size = New-Object System.Drawing.Size(600, 300) # 根据需要添加自定义控件的项 $t = $objCustom.Controls.Item("ServerName") $t.Items.Add("TestServer1") $t.Items.Add("TestServer2") $t = $objCustom.Controls.Item("ShareName") $t.Items.Add("C$") $t.Items.Add("MyShare") $t = $objCustom.Controls.Item("Credentials") $t.Items.Add("Computername\Username") $t.Items.Add("DomainName\Username") $t = $objCustom.Controls.Item("PSProvider") $t.Items.Add("testprovider") $t = $objCustom.Controls.Item("Credentials") $t.Items.Add("domain\username") # 添加主窗体功能并运行窗体 $OKButton = New-Object System.Windows.Forms.Button $OKButton.Location = New-Object System.Drawing.Size(500, 260) $OKButton.Size = New-Object System.Drawing.Size(75, 23) $OKButton.Text = "OK" $OKButton.Add_Click({$y = $objCustom; $objForm.Close()}) $objForm.Controls.Add($OKButton) $objForm.Controls.Add($objCustom) $objForm.Topmost = $True [void] $objForm.ShowDialog() # 创建UNC路径变量 $z = "\\" + $y.Controls.Item("ServerName").Text + "\" + $y.Controls.Item("ShareName").Text # 测试凭据变量并根据其是否存在调用正确的映射命令 if ($x.Text -eq "") { New-PSDrive -Name $y.Controls.Item("DriveLetter").Text -PSProvider $y.Controls.Item("PSProvider").Text -Root $z } else { New-PSDrive -Name $y.Controls.Item("DriveLetter").Text -PSProvider $y.Controls.Item("PSProvider").Text -Root $z -Credential $x.Text }

在上述脚本中,首先加载了“PSMap”程序集,并初始化了一个包含自定义控件的窗体。然后,为控件添加了一些预定义的项,并设置了窗体的事件处理程序。最后,根据用户输入的参数创建了一个新的PSDrive。
