如何在 PowerShell 中设置标签的背景透明? [英] How Can I set a label's background transparent in PowerShell?

问题描述

我在将 System.Winfows.Forms.Label 背景设置为透明时遇到问题.

I have problems to set a System.Winfows.Forms.Label background to transparent.

在 C# 中很容易:

this.label1.BackColor = System.Drawing.Color.Transparent;

但是在我的 PowerShell GUI 中我无法获得相同的结果.我尝试了很多变体，但没有一个成功:

However in my PowerShell GUI I can't acchieve the same result. I tried many variants, but none worked out:

$my_label = New-Object System.Windows.Forms.Label
$my_label.BackColor = System.Drawing.Color.FromName("Transparent")

或

$my_color = New-Object System.Drawing.Color.Transparent
$my_label.BackColor = $my_color

在 C# 中，您可以超越这些样本，结果标签的背景将变得透明.然而，在 PowerShell 中，每次尝试都会导致不同的错误.

In C# you can overtake those samples and the resulting label's background becomes transparent. In PowerShell, however, every attempt resulted in different errors.

我是不是注意到了什么?

Haven't I paid regard to something?

推荐答案

您是否尝试过这种语法?

Have you tried this syntax?

$my_label.BackColor = [System.Drawing.Color]::FromName("Transparent")

对于像这样的静态方法，类的全名用括号括起来，然后是 2 个冒号，然后是方法名称和括号中的参数(与常规 PowerShell 方法不同).

For a static method such as this, the full name of the class surrounded by brackets, then 2 colons then the method name and parameters in parenthesis (unlike a regular PowerShell method).
