说明
The Get-ItemProperty cmdlet gets the properties of the specified items. For example, you can use
this cmdlet to get the value of the LastAccessTime property of a file object. You can also use
this cmdlet to view registry entries and their values.
示例
Example 1: Get information about a specific directory
This command gets information about the C:\Windows directory.
Get-ItemProperty C:\Windows
Example 2: Get the properties of a specific file
This command gets the properties of the C:\Test\Weather.xls file. The result is piped to the
Format-List cmdlet to display the output as a list.
Get-ItemProperty C:\Test\Weather.xls | Format-List
Example 3: Get the value name and data of a registry entry in a registry subkey
This command gets the value name and data of the ProgramFilesDir registry entry in the
CurrentVersion registry subkey. The Path specifies the subkey and the Name parameter
specifies the value name of the entry.
Get-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion -Name "ProgramFilesDir"
Note
This command requires that there is a PowerShell drive named HKLM: that is mapped to the
HKEY_LOCAL_MACHINE hive of the registry.
A drive with that name and mapping is available in PowerShell by default. Alternatively, the path to this registry subkey can be specified by using the following alternative path that begins with the provider name followed by two colons:
Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion.
Example 4: Get the value names and data of registry entries in a registry key
This command gets the value names and data of the registry entries in the PowerShellEngine
registry key. The results are shown in the following sample output.
Get-ItemProperty -Path HKLM:\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine
ApplicationBase : C:\Windows\system32\WindowsPowerShell\v1.0\
ConsoleHostAssemblyName : Microsoft.PowerShell.ConsoleHost, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=msil

-Exclude
Specifies, as a string array, an item or items that this cmdlet excludes in the operation. The value
of this parameter qualifies the Path parameter. Enter a path element or pattern, such as
*.txt. Wildcard characters are permitted. The Exclude parameter is effective only when the
command includes the contents of an item, such as C:\Windows\*, where the wildcard character
specifies the contents of the C:\Windows directory.

-Filter
Specifies a filter to qualify the Path parameter. The FileSystem provider is the only installed PowerShell provider that supports the use of filters. You can find the syntax for the FileSystem filter language in about_Wildcards. Filters are more efficient than other parameters, because the provider applies them when the cmdlet gets the objects rather than having PowerShell filter the objects after they are retrieved.

-LiteralPath
Specifies a path to one or more locations. The value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell PowerShell not to interpret any characters as escape sequences.
For more information, see about_Quoting_Rules.
