PowershellでTypeからメンバーを取得する
.netのクラスは取得できた。
http://d.hatena.ne.jp/junjun777/20140115/powershell_search_type
しかし、コンストラクターがわからない。
から、インスタンスのメンバーがわからない、という事態が発生する。
そこで、また関数を書いてみた。
関数
function Get-TypeMember() { Param( $Target, [switch]$Static, [switch]$Private ) if($Target -is [String]) { if($Target -match '^\[[^\]]+]$') { $Target = (($Target -replace '^\[([^\]]+)]$', '$1') -as [type]) } else { $ts = (Get-Types $Target) if($ts -ne $null -and -not $ts.length) { $Target = $ts } elseif(!$ts.length) { Write-Error ($Target + ' is not found!') $Target = $null } else { $ts | %{ Write-Host ('[' + $_.FullName + ']') } return Get-TypeMember (Read-Host ?) } } } $res = @() if($Target -is [Type]) { function getMembersSub($tar, [string]$para, [string]$pre) { function getTypeName($type) { $res = $type.ToString() $res = $res -replace 'System.Boolean', 'bool' $res = $res -replace 'System.String', 'string' $res = $res -replace 'System.Int32', 'int' $res = $res -replace 'System.Char', 'char' return $res } $res = @() foreach($mi in $tar.GetMembers($para)) { $def = '' if(-not $mi.IsPublic -and ($mi.MemberType -ne 'Property' -and $mi.MemberType -ne 'NestedType')) { $def = '# ' } $def += $pre $type = $mi.MemberType.ToString() switch($type) { Method { $def += (getTypeName $mi.ReturnType) + ' ' + $mi.Name + '(' $comma = $false foreach($pi in $mi.GetParameters()) { if($comma) { $def += ', ' } $def += (getTypeName $pi.ParameterType) + ' ' + $pi.Name $comma = $true } $def += ')' } Constructor { $type = 'CodeMethod' $def += $tar.Name + '(' $comma = $false foreach($pi in $mi.GetParameters()) { if($comma) { $def += ', ' } else { $comma = $true } $def += (getTypeName $pi.ParameterType) + ' ' + $pi.Name } $def += ')' } Property { $def += (getTypeName $mi.PropertyType) + ' ' + $mi.Name $comma = $true foreach($pi in $mi.GetIndexParameters()) { if($comma) { $def += '('; $type = 'ParameterizedProperty'; $comma = $false } else { $def += ', ' } $def += (getTypeName $pi.ParameterType) + ' ' + $pi.Name } if(-not $comma) { $def += ')' } $def += ' {' if($mi.CanRead) { $def += 'get;' } if($mi.CanWrite) { $def += 'set;' } $def += '}' } Field { $type = 'Properties' $def += (getTypeName $mi.FieldType) + ' ' + $mi.Name } NestedType { $type = 'PropertySet' $def += $tar.FullName + '+' + $mi.Name } } $res += (New-Object Microsoft.Powershell.Commands.MemberDefinition($Target.FullName, $mi.Name, $type, $def)) #if($type -eq 'PropertySet') { $res += (getMembersSub $mi $para $pre) } } return $res } $def = '' if($Static) { $def = 'static ' $ts = 'Static, Public' } else { $ts = 'Instance, Public' } if($Private) { $ts += ', NonPublic' } $res = getMembersSub $Target $ts $def } elseif($Target -ne $null) { $res = (Get-Member -InputObject $Target) } return $res }
都合により、Fieldは「Properties」、NestedTypeは「PropertySet」と表示されますが、だいたいGet-Memberと同じ表示となっています。
使い方
基本的にはTypeの名前を渡すと、そのメンバーを表示してくれます。
Get-TypeMember StreamReader
とかやると

てな感じ。
複数あるような名前を指定すると
Get-TypeMember FileStream
[System.IO.FileStream] [System.IO.IsolatedStorage.IsolatedStorageFileStream] [System.Data.SqlTypes.SqlFileStream] ?:
とか表示して、どれか聞いてくる。
ので、「[System.IO.FileStream]」とかコピペするとそれが出る。
もちろん最初から、
Get-TypeMember [System.IO.FileStream]
としても良い。
「-Private」オプションを付与すると、NonPublicなメンバーも表示します。
NonPublicなものには、Definitionに「#」が付与されています。
「-Static」オプションは、この調子でStaticメンバーも取得できるね、と思ってやったのですが

Get-Memberでできることでした。

まー、タイプ数が少ないというメリットがあるか。
ちなみに、NestedTypeは+でアクセスする。
