PowerShell的学习笔记(2)

我们在使用PowerShell脚本的时候，帮助文档特别的重要。除了能在PowerShell的控制台中查看帮助信息外，我们还能借助于第三方工具，进行PowerShell帮助文档的查看；总的来说有三种。

@ 能以图形化方式列出所有可用的帮助主题。

大家可以到下面这个网站

把当前的PowerShell脚本复制并另存为PS_Help_About.ps1，然后运行这个脚本，就会看到下面的帮助文档。



脚本如下：

function Add-Node {
param (
$selectedNode,
$name,
$tag
)
$newNode = new-object System.Windows.Forms.TreeNode
$newNode.Name = $name
$newNode.Text = $name
$newNode.Tag = $tag
$selectedNode.Nodes.Add($newNode) | Out-Null
return $newNode
}

function Get-HelpTree {
if ($script:cmdletNodes)
{
$treeview1.Nodes.remove($script:cmdletNodes)
$form1.Refresh()
}
$script:cmdletNodes = New-Object System.Windows.Forms.TreeNode
$script:cmdletNodes.text = "PowerShell Help"
$script:cmdletNodes.Name = "PowerShell Help"
$script:cmdletNodes.Tag = "root"
$treeView1.Nodes.Add($script:cmdletNodes) | Out-Null

$treeView1.add_AfterSelect({
if ($this.SelectedNode.Tag -eq "Cmdlet") {
$helpText = Get-Help $this.SelectedNode.Name -Full
$richTextBox1.Text = $helpText | Out-String
$linkLabel1.Text = $helpText.relatedLinks.navigationLink[0].uri
$form1.refresh()
} else {
$richTextBox1.Text = "Example to show how to use TreeView control in PowerShell script"
$linkLabel1.Text = "http://www.ravichaganti.com/blog"
}
})

#Generate Module nodes
$modules = @("Microsoft.PowerShell.Core","Microsoft.PowerShell.Diagnostics","Microsoft.PowerShell.Host","Microsoft.PowerShell.Management","Microsoft.PowerShell.Security","Microsoft.PowerShell.Utility")

$modules | % {
$parentNode = Add-Node $script:cmdletNodes $_ "Module"
$moduleCmdlets = Get-Command -Module $_
$moduleCmdlets | % {
$childNode = Add-Node $parentNode $_.Name "Cmdlet"
}
}
$script:cmdletNodes.Expand()
}
