Powershell中声明、使用类

Powershell提供的默认类型往往不能满足工作中的各种需求，所以使用自定义类型相当有必要。

下面就先举个栗子：

$vmConfigInformation = @" 
public class vmInfo
{
    public string vmName;
    public int ioCount;
    public string[] traceFiles;
    
    public vmInfo ( string vm,
                    int count,
                    string[] trace
                    )
    {
        this.vmName = vm;
        this.ioCount = count;
        this.traceFiles = trace;
    }
} 
"@

Add-Type -TypeDefinition $vmConfigInformation

$testVmName = "win8testing"
$testCount = 10
$testTraceFiles = @("trace01.csv", "trace02.csv", "trace03.csv")

$test = New-Object vmInfo( $testVmName,
                             $testCount,
                             $testTraceFiles);
                         
                         
Write-Host "VM Name:" $test.vmName
Write-Host "VM IO Count:" $test.ioCount
Write-Host "VM Trace Files:" $test.traceFiles

运行结果：

有了这些自定义类型，工作起来着实方便了不少。
