Question

您好我是PowerShell的新手。我正在尝试进行ETL数据库部署，所以我需要在给定时间后在tfs文件夹中的所有文件。我建立了与tfs的连接，但我能够下载文件但是如果一个文件有两个签到我得到的文件与之前的签到而不是最新的

我的代码：

$TfsUrl = "http://tfs2013-xxx02.ad.xxx.com:8080/tfs/abcd-xxx243"

    # Load TFS assemblies for connecting to the TFS server 
    Add-Type -Path "E:\Microsoft Visual Studio 14.0\Common7\IDE\TestAgent\Microsoft.TeamFoundation.Client.dll"
    Add-Type -Path "E:\Microsoft Visual Studio 14.0\Common7\IDE\TestAgent\Microsoft.TeamFoundation.Common.dll"
    Add-Type -Path "E:\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\4qvjm2or.ipa\Microsoft.TeamFoundation.Lab.Client.dll"
    Add-Type -Path "E:\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\4qvjm2or.ipa\Microsoft.TeamFoundation.Lab.Common.dll"
    Add-Type -Path "E:\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\4qvjm2or.ipa\Microsoft.TeamFoundation.VersionControl.Client.dll"

    #Get TFS Instance   
    $Tfs = [Microsoft.TeamFoundation.Client.TfsTeamProjectCollectionFactory]::GetTeamProjectCollection($TfsUrl)

    # use the account credentials of the process running the script
    try 
    {
        $Tfs.EnsureAuthenticated()
        Write-Output "TFS Connection is successful"
    }
    catch 
    {
        Write-Output "Error trying to connect to tfs server.  Check your tfs permissions and path: $_ " 
        Exit(1)
    }

    #Write-Message $LogFileName "THIS IS INSIDE Connect-ToTFS"
    #Write-Message $LogFileName "TFS IS $Tfs"

$DeploymentFilePath= "$/xxxx/FutureReleases/Database/ReportingETLs"

$TFSInstance    = $Tfs.GetService([Microsoft.TeamFoundation.VersionControl.Client.VersionControlServer])
$LatestVersion  = [Microsoft.TeamFoundation.VersionControl.Client.VersionSpec]::Latest
$RecursionType  = [Microsoft.TeamFoundation.VersionControl.Client.RecursionType]::Full  


$DateFrom   = "D2016-10-08T01:59"

# Get the From and To date-time in version format to be passed to TFS API
$VersionFrom    = $null 
$VersionFrom    = [Microsoft.TeamFoundation.VersionControl.Client.VersionSpec]::ParseSingleSpec($DateFrom, "")      

$FileHistory    = @($TFSInstance.QueryHistory($DeploymentFilePath,$LatestVersion,0,$RecursionType,$null,$null,$null,[int32]::MaxValue, $true ,$true, $true))

#Write-Output "Filehistory is: $FileHistory"

#$ChangeSetCount = $FileHistory.Count
#Write-Output "ChangeSetCount is: $ChangeSetCount"


$TFSGetFullPath = "E:\temp\"
$chArray = @()
$checkin =""

foreach ($history in $FileHistory)
{
    foreach ($change in $history.Changes)
    {
        foreach ($item in $change.item)
        {

            if($item.CheckinDate -gt $VersionFrom.Date)
            {
                $chArray += $history.ChangesetId 


            }
        }
    }
}

Write-Output "ChangesetArray is: $chArray"
foreach ($ch in $chArray) 
{
    foreach ($lastdeployedHistory in $FileHistory)       
    {      
        if($lastdeployedHistory.ChangesetId -eq  $ch)
        {
            foreach ($workitem in $lastdeployedHistory.Changes)
            { 
                $workitem.Item.DownloadFile([IO.Path]::GetFullPath($TFSGetFullPath) + $workitem.Item.ServerItem.Split('/')[$workitem.Item.ServerItem.Split('/').Length - 1]);
            }
        }                                                                                                                
    }
}

这是由$ chArray中的对象顺序引起的。 $ chArray中的变更集按从新到旧排序。下载文件时，它首先下载新文件，然后下载旧文件。

例如，一个文件有两个变更集：111和112，脚本中的代码为Write-Output "ChangesetArray is: $chArray"，您应该看到如下输出：ChangesetArray is: 112 111。下载文件时，首先下载112版本的文件，然后下载覆盖最新版本的111版本。

您可以在$ chArray中对数组进行排序以解决此问题：

Write-Output "ChangesetArray is: $chArray"

$sortcsarray = $chArray | Sort-Object

Write-Output "ChangesetArray is: $sortcsarray"

foreach ($ch in $sortcsarray)

使用powershell从tfs文件夹中获取最新的签入文件
