用於應用Entity Framework遷移的PowerShell？

Question

我正在使用PowerShell來應用EF遷移。它正在運行，唯一的問題是如果在應用遷移時出現任何錯誤，它仍然會成功。如果在應用遷移時出現任何錯誤，我希望能夠引發異常。找不到如何做到這一點的任何事情。這裏是我的腳本：

try 
{ 
#all relative paths are relative to where xyzabc.sln is 

#copy migrate.exe to xyzabcWebRole\bin 
Copy-Item packages\EntityFramework*\tools\migrate.exe xyzabc\path\xyzabcWebRole\bin -ErrorAction "Stop" 

#migrate 
$migrator = "C:\TeamCity\buildAgent\work\f791999b69d7a83e\packages\EntityFramework.6.1.3\tools\migrate.exe" 
$migrateCommand = "$migrator xyzabcWebRole.dll /StartUpDirectory=C:\TeamCity\buildAgent\work\f791999b69d7a83e\xyzabcWebRole\bin /connectionStringName:MyDBConnectionString /startUpConfigurationFile:C:\TeamCity\buildAgent\work\f791999b69d7a83e\xyzabc\path\xyzabcWebRole\Web.config /verbose" 

Write-Host $migrateCommand 
Invoke-Expression $migrateCommand 


} 
    catch [System.Exception] 
{ 
Write-Host $_.Exception.ToString() 
exit 1 
}

檢查你調用遷移並拋出一個異常
