如何知道winform的名称。事件会触发脚本块？

发布于 2025-02-13 05:55:17 字数 909 浏览 0 评论 0原文

我构建了一个pswinform构建器，

每个事件在$ threadeventhandler列表中都有一个scriptblock，它们被命名为control.name.name -event.name.name。

$ThreadEventHandler["Button1-Click"] = [ScriptBlock]{...}

当我在controler.event上添加简单的ScriptBlock时，没关系。

但是对于较慢的脚本block，我希望该事件使用 start -threadjob whit scriptblock nater control.name-event.name.name在事件中，我使用$ $ this.name 对于control.name，并且我没有向$ thisevent.name提供

$Form.Button1.Add_Click({
    Start-ThreadJob -ScriptBlock $ThreadEventHandler["$($this.Name)-$($ThisEvent.Name)"]
})

transmit $ thisevent.name的想法事件scriptblock？

I construct a PSWinForm-Builder,

Each event has a Scriptblock in a list of $ThreadEventHandler they are named Control.Name - Event.Name.

$ThreadEventHandler["Button1-Click"] = [ScriptBlock]{...}

when i add simple scriptblock on controler.event it is ok.

But for slower scriptblock i want the event use Start-ThreadJob whit scriptblock named Control.Name - Event.Name, in event I use $this.Name for Control.Name and i haven't acces to $ThisEvent.Name

$Form.Button1.Add_Click({
    Start-ThreadJob -ScriptBlock $ThreadEventHandler["$($this.Name)-$($ThisEvent.Name)"]
})

Have you an idea for transmit $ThisEvent.Name in Event ScriptBlock ?

基于指向源代码的链接，我建议通过[scriptblock] :: create（）而不是使用script-block literal来创建您的脚本块。 （{...}），因为这使您可以“烘烤” $ evt变量，其中包含事件名称到脚本块中；请注意，如何将NOM 不应该扩展的变量引用（interpolated）提前扩展（Interpolated）将其$ Sigil逃脱为`$。

$Script:ControlHandler[$Name]."Add_$($Evt)"(
  [scriptblock]::Create(@"
    param(`$caller, `$e)
    Start-ThreadJob -Name "`$(`$this.Name)-$Evt" -ScriptBlock `$Script:ThreadEventHandler["`$(`$this.Name)-$Evt"].ScriptBlock
"@)
)

Based on the link to your source code, I suggest creating your script block from an expandable (here-)string via [scriptblock]::Create() instead of using a script-block literal ({ ... }), as that allows you to "bake" the value of the $Evt variable containing the event name into the script block; note how the variable references that should not be expanded (interpolated) up front have their $ sigil escaped as `$.

$Script:ControlHandler[$Name]."Add_$($Evt)"(
  [scriptblock]::Create(@"
    param(`$caller, `$e)
    Start-ThreadJob -Name "`$(`$this.Name)-$Evt" -ScriptBlock `$Script:ThreadEventHandler["`$(`$this.Name)-$Evt"].ScriptBlock
"@)
)
