The data type of a variable is determined by the .NET types of the values of the variable. To view a variable's object type, useGet-Member. For example: PowerShell $a=12# System.Int32$a="Word"# System.String$a=1
$x = New-Module -AsCustomObject {$M = 123 ; Export-ModuleMember --Variable M} 此方法可用于添加任何类型的成员。 PowerShell 复制 $x = New-Object PSObject Add-Member -InputObject $x -Name M -MemberType NoteProperty -Value 123 PSObject 是所有 PowerShell 类型的基类型。在...

Windows PowerShell will use the String data type to store the value. In .NET Framework terms, that's the System.String class, which has perhaps the most built-in functionality of any variable type. If, say, I want to see an all-lowercase version of the value in $var, I can do this...
For more information, see the documentation for the ftype command. For PowerShell to see a file extension as executable in the current session, you must add the extension to the $env:PATHEXT environment variable. See also - about_Aliases - about_Functions - about_Path_Syntax - Alias-...
如果不想继续使用自定义的变量,可以使用del variable:变量名的方法删除变量,注意此处无$符号 $a=0$a-eq$nullFalsedelvariable:a$a-eq$nullTrue PowerShell支持的变量类型和C#大体相同(没有了short、uint、ulong等),大多都继承自System.ValueType类( .NET类),其基本数据类型包括 ...
在命令上使用ErrorVariable参数时,PowerShell 还会将命令发出的错误记录存储在参数指定的变量中。 YAML Type:StringAliases:evRequired:FalsePosition:NamedDefaultvalue:NoneAcceptpipelineinput:FalseAcceptwildcardcharacters:False 默认情况下,新错误消息将覆盖已存储在变量中的错误消息。 若要将错误消息追加到变量内容,请将...
Type Operators Use the type operators (-is,-isnot,-as) to find or change the .NET type of an object. For more information, seeabout_Type_Operators. Unary Operators Use the unary++and--operators to increment or decrement values and-for negation. For example, to increment the variable$afro...
