Get-Member for object inspection in PowerShell - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to list all properties and methods of the object stored in $obj.

PowerShell

$obj | [1]

Drag options to blanks, or click blank then click option'

AGet-Member

BSelect-Object

CFormat-Table

DGet-Content

💡 Hint

Common Mistakes

Using Get-Content which reads file content, not object members.

Using Select-Object which selects properties but doesn't list all members.

The Get-Member cmdlet shows the properties and methods of an object in PowerShell.

2fill in blank

medium

Complete the code to show only the methods of the object $item.

PowerShell

$item | Get-Member -MemberType [1]

Drag options to blanks, or click blank then click option'

AProperty

BMethod

CEvents

DAliasProperty

💡 Hint

Common Mistakes

Using Property which shows data fields, not actions.

Using Events which shows event handlers, not methods.

The -MemberType Method option filters the output to show only methods.

3fill in blank

hard

Fix the error in the code to correctly get the properties of $data.

PowerShell

$data | Get-Member -MemberType [1]

Drag options to blanks, or click blank then click option'

Amethods

BProps

Cproperty

DProperty

💡 Hint

Common Mistakes

Using plural forms like 'methods' or 'properties' which cause errors.

Using incorrect member type names like 'Props'.

The -MemberType parameter expects the exact member type name, which is Property with capital P and singular.

4fill in blank

hard

Fill both blanks to list only the properties of $record and display their names.

PowerShell

$record | Get-Member -MemberType [1] | Select-Object [2]

Drag options to blanks, or click blank then click option'

AProperty

BMethod

CName

DValue

Attempts:

3 left

💡 Hint

Common Mistakes

Selecting 'Value' instead of 'Name' which does not exist in this context.

Filtering by 'Method' instead of 'Property'.

Use Property to filter member type and Name to select the property names.

5fill in blank

hard

Fill all three blanks to get methods of $obj that start with 'Get' and select their names.

PowerShell

$obj | Get-Member -MemberType [1] | Where-Object { $_.Name -like '[2]' } | Select-Object [3]

Drag options to blanks, or click blank then click option'

AMethod

BGet*

CName

DProperty

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'Property' instead of 'Method' in the first blank.

Using incorrect wildcard patterns or missing quotes.

Selecting 'Property' instead of 'Name' in the last blank.

Filter for Method, then use Where-Object to find names starting with 'Get', and finally select the Name property.

Practice

1. What is the main purpose of the Get-Member cmdlet in PowerShell?

easy

A. To execute a script block on an object

B. To list the properties and methods of an object

C. To delete an object from memory

D. To create a new object instance

Solution

1. Step 1: Understand what Get-Member does

   Get-Member shows the properties and methods available on an object, helping you explore it.

2. Step 2: Compare options with Get-Member purpose

   Options B, C, and D describe actions unrelated to inspecting object members.

3. Final Answer:

   To list the properties and methods of an object -> Option B

4. Quick Check:

   Get-Member = List properties and methods [OK]

Hint: Remember: Get-Member shows what an object has and can do [OK]

Common Mistakes:

• Thinking Get-Member runs code on the object
• Confusing Get-Member with object creation
• Assuming it deletes or modifies objects

2. Which of the following is the correct syntax to use Get-Member to inspect the properties of the output from Get-Process?

easy

A. Get-Process | Get-Member

B. Get-Member | Get-Process

C. Get-Process Get-Member

D. Get-Process > Get-Member

Solution

1. Step 1: Understand piping in PowerShell

   The pipe symbol | sends output from one command as input to another.

2. Step 2: Apply piping to Get-Process and Get-Member

   Correct syntax is Get-Process | Get-Member to inspect process objects.

3. Final Answer:

   Get-Process | Get-Member -> Option A

4. Quick Check:

   Pipe output to Get-Member = Get-Process | Get-Member [OK]

Hint: Use pipe (|) to send output to Get-Member [OK]

Common Mistakes:

• Reversing the order of commands
• Using spaces instead of pipe
• Trying to redirect output with >

3. What will be the output type when you run Get-Process | Get-Member -MemberType Property?

medium

A. List of properties of process objects

B. List of all processes running

C. List of methods of process objects

D. Error message about invalid syntax

Solution

1. Step 1: Understand the -MemberType Property filter

   This filter limits output to only properties of the object, excluding methods.

2. Step 2: Apply filter to Get-Process output

   The command lists only properties (like Id, ProcessName) of each process object.

3. Final Answer:

   List of properties of process objects -> Option A

4. Quick Check:

   MemberType Property = Properties listed [OK]

Hint: Use -MemberType Property to see only properties [OK]

Common Mistakes:

• Confusing properties with methods
• Expecting process list instead of members
• Assuming syntax error due to filter

4. You run the command Get-Process | Get-Member -MemberType ScriptMethod but get no output. What is the most likely reason?

medium

A. The -MemberType parameter is misspelled

B. The pipeline is missing before Get-Member

C. The objects returned by Get-Process have no methods

D. You used the wrong parameter value for -MemberType

Solution

1. Step 1: Check the -MemberType parameter value

   The correct value for methods is 'Method' (singular). Using a wrong value returns no results.

2. Step 2: Verify other options

   Options A and B would cause errors, not empty output. The objects returned by Get-Process have methods, so The objects returned by Get-Process have no methods is false.

3. Final Answer:

   You used the wrong parameter value for -MemberType -> Option D

4. Quick Check:

   Wrong -MemberType value = no output [OK]

Hint: Check exact spelling of -MemberType values [OK]

Common Mistakes:

• Using plural 'Methods' instead of 'Method'
• Forgetting the pipe symbol
• Assuming no methods exist on objects

5. You want to find only the properties of a service object that start with 'Status'. Which command correctly uses Get-Member to filter these properties?

hard

A. Get-Service | Get-Member -MemberType Property | Where-Object Name -like 'Status*'

B. Get-Service | Get-Member -MemberType Property Name 'Status*'

C. Get-Service | Get-Member -MemberType Property | Where-Object { $_.Name -like 'Status*' }

D. Get-Service | Get-Member -MemberType Property -Filter 'Status*'

Solution

1. Step 1: Understand filtering with Get-Member

   Get-Member does not support a -Name or -Filter parameter for partial matches, so filtering must be done after.

2. Step 2: Use Where-Object to filter properties by name

   Get-Service | Get-Member -MemberType Property | Where-Object { $_.Name -like 'Status*' } correctly pipes Get-Member output to Where-Object with a script block filtering names starting with 'Status'.

3. Final Answer:

   Get-Service | Get-Member -MemberType Property | Where-Object { $_.Name -like 'Status*' } -> Option C

4. Quick Check:

   Filter after Get-Member with Where-Object [OK]

Hint: Filter Get-Member output using Where-Object script block [OK]

Common Mistakes:

• Trying to use -Name or -Filter with Get-Member
• Using Where-Object without script block
• Filtering before Get-Member instead of after
