我正在编写一个使用第三方库的PowerShell脚本。我正在使用的一个对象要求我添加一个事件处理程序。 The event delegate looks like this:
public delegate void TSBPGPCreateOutputStreamEvent(object Sender,
string Filename,
System.DateTime TimeStamp,
ref System.IO.Stream Stream,
ref bool FreeOnExit)
在PowerShell中,我尝试过这样做:
$reader.Add_OnCreateOutputStream( {
param(
$sender,
$fileName,
$timestamp,
[ref]
$stream,
[ref]
$freeOnExit
)
$stream = New-Object IO.MemoryStream
} )
但是我收到了这条错误消息:
Cannot convert value "
param(
$sender,
$fileName,
$timestamp,
[ref]
$stream,
[ref]
$freeOnExit
)
$stream = New-Object IO.MemoryStream
" to type "SBPGP.TSBPGPCreateOutputStreamEvent".
Error: "The type 'System.IO.Stream&' may not be used as a type argument."
订阅活动有更好的方法吗?为什么Stream类型不能用作类型参数?我做错了什么?

您应该使用Register-ObjectEvent cmdlet,使用以下命令查看您自己系统上的示例:

Add-Type -AssemblyName System.Windows.Forms
[reflection.assembly]::loadwithpartialname("System.Drawing") | Out-Null
$form = New-Object Windows.Forms.Form
$form.add_mousedown($handler_form_mousedown)
$handler_form_Mousedown=
{
param([object]$sender, [System.EventArgs]$e)
write-host $e.x
write-host $e.y
$sender.text="if ya think your so noble answer the question"
$sender.text = "Nobles Oblige"
# PS HELP IS USELESS FOR THIS
}
$App = $form.ShowDialog()
