PowerShell script to read and increment value inside json file everytime after checkout

参考以下PowerShell脚本：

$pathToJson = "path/test.json"
$a = Get-Content $pathToJson | ConvertFrom-Json

$VMName = $a.parameters.VMName.value
echo $VMname
$len = $VMName.Length
$number= "$VMName".Substring($len - 2, 2)
echo $number

$number = [int]$number+1

echo $number

$NewVMName = $VMName.replace('19',$number)

echo $NewVMName

$a.parameters.VMName.value = $NewVMName

$a | ConvertTo-Json | set-content $pathToJson

PowerShell 脚本将查找 VMName 字段的值。然后它会得到字符串中的数字和增量+1.

结果：
