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。
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。
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。
