获取 "Supply an argument that is in the set and then try the command again"

Question

我正在使用 PS 创建 Dynamics 环境，效果非常好。 https://docs.microsoft.com/en-us/powershell/module/Microsoft.PowerApps.Administration.PowerShell/new-adminpowerappenvironment?view=pa-ps-latest

我正在为所有用户启用一个选项来创建环境，并希望为他们创建一个简单的表单来创建新环境。我测试并检查了很多建议，但我似乎无法将 TextBox-es 中的数据提取到命令中。首先，我使用带有预定义值的下拉菜单测试选项，但出现以下错误：

New-AdminPowerAppEnvironment : Cannot validate argument on parameter 'EnvironmentSku'. The argument "$($TextBox1.Text)" does not 
belong to the set "Trial,Sandbox,Production,SubscriptionBasedTrial,Teams" specified by the ValidateSet attribute. Supply an argument 
that is in the set and then try the command again.

然后我将所有内容都更改为 TextBox，但还是出现同样的错误。以下是表格：

    $x = New-AdminPowerAppEnvironment -EnvironmentSku '$($TextBox1.Text)' -LocationName europe -CurrencyName '$($TextBox2.Text)' -DisplayName '$($TextBox3.Text)' -LanguageName '$($TextBox4.Text)' -ProvisionDatabase -RegionName westeurope -WaitUntilFinished 1
    $x
}

注意：如果您没有试用版或 Dynamics 订阅，您很可能无法测试脚本，但对于在表单中设置值的正确方法的任何建议，我将不胜感激。

提前致谢。

Answer 1

在 PowerShell 字符串中引用变量时，使用双引号 (") 而不是单引号 (')

所以

... -EnvironmentSku "$($TextBox1.Text)" ...

而不是

... -EnvironmentSku '$($TextBox1.Text)' ...

错误信息拼写得很清楚，但很容易错过！它的字面意思是“$($TextBox1.Text)”，它不是指变量在运行时的实际值。

为了避免在传递除了变量之外没有任何其他参数时出现此问题，只需按如下所示不带引号传递它：

... -EnvironmentSku $TextBox1.Text ...

请参阅此 link，其中显示了引用规则：https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_quoting_rules?view=powershell-7.1
