只需要在VS2012中运行下面代码即可：
Tools->Library Package Manager->Package Manager Console
function FormatItems($projectItems) {
$projectItems |
% {
# Write-Host " Examining item: $($_.Name)";
if ($_.Name -and $_.Name.ToLower().EndsWith(".cs") `
-and (-not $_.Name.ToLower().Contains(".designer."))) {
$win = $_.Open('{7651A701-06E5-11D1-8EBD-00A0C90F26EA}');
$win.Activate();
$dte.ExecuteCommand('Edit.FormatDocument');
if (!$_.Saved) {
Write-Host " Saving modified file: $($_.Name)";
$dte.ExecuteCommand('File.SaveSelectedItems');
}
$dte.ExecuteCommand('Window.CloseDocumentWindow');
}
if ($_.ProjectItems -and ($_.ProjectItems.Count -gt 0)) {
# Write-Host " Opening sub-items of $($_.Name)";
FormatItems($_.ProjectItems);
}
};
}
$dte.Solution.Projects | % {
Write-Host "-- Project: $($_.Name)";
FormatItems($_.ProjectItems)
}
;
注意：上面代码会遍历文件，打开，格式化，保存再关闭。运行前请保存并备份！
