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()
