创建循环以在 Powershell 中创建新资源组

Question

我需要创建一个循环来检查资源组名称是否被使用，如果没有使用该名称创建一个新资源组。

这是我用来尝试完成此操作的代码

do
{
    $rg = Read-Host -Prompt "What would you like to name the new Resource Group"
    if (!(Get-AzureRmResourceGroup -ResourceGroupName $rg -ErrorAction Ignore)) 
    {
        New-AzureRmResourceGroup -ResourceGroupName $rg -Location "West Europe"
    } 
    else {
        $rg = Read-Host -Prompt "Resouce Group name not available, please select another"
        New-AzureRmResourceGroup -ResourceGroupName $rg -Location "West Europe"
    }

}
while (!(Get-AzureRmResourceGroup -ResourceGroupName $rg -ErrorAction Ignore))

Answer 1

你说的："I want a user to enter a number, and keep entering if until they enter something > 10".

您编码的内容："Enter a number, test if it's < 10 and prompt again. Don't test this one, go with it without testing it. Now loop all of that."

do
{
    # coming round from a previous loop, $num exists, indicating this is a retry.
    if ($null -ne $num) { Write-Host "Sorry, try again" }

    [int]$num = Read-Host "Enter a number"

} until ($num -gt 10)
