There are many tools that output their data in in a table format. One such example is diskpart. Shaving off some extraneous output, you would get something like this.
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 136 GB 0 B
Disk 1 Offline 136 GB 136 GB
Disk 2 Reserved 1027 MB 0 B *
Disk 3 Reserved 500 GB 0 B *
Disk 4 Reserved 500 GB 0 B *
Disk 5 Reserved 10 GB 0 B *
Disk 6 Reserved 13 GB 0 B *
Disk 7 Reserved 4102 MB 0 B *
Disk 8 Reserved 7169 MB 0 B *
Disk 9 Reserved 503 GB 0 B *
Disk 10 Reserved 506 GB 0 B *
Disk 11 Reserved 500 GB 0 B *
Disk 12 Reserved 3891 GB 0 B *
Disk 13 Reserved 500 GB 0 B *
Disk 14 Reserved 3891 GB 0 B *
Disk 15 Reserved 1843 GB 0 B
Disk 16 Reserved 3072 GB 0 B *
Disk 17 Reserved 2048 GB 0 B *
Disk 18 Reserved 808 GB 0 B *
Disk 19 Reserved 805 GB 0 B *
Disk 20 Reserved 3891 GB 0 B *
Disk 21 Reserved 3891 GB 0 B *
Disk 22 Reserved 3891 GB 0 B *
Disk 23 Reserved 6144 GB 0 B *
Another example is netstat, which looks like the following:
Proto Local Address Foreign Address State
TCP 0.0.0.0:80 7ANDYS:0 LISTENING
TCP 0.0.0.0:135 7ANDYS:0 LISTENING
TCP 0.0.0.0:443 7ANDYS:0 LISTENING
TCP 0.0.0.0:445 7ANDYS:0 LISTENING
TCP 0.0.0.0:1025 7ANDYS:0 LISTENING
TCP 0.0.0.0:1026 7ANDYS:0 LISTENING
TCP 0.0.0.0:1027 7ANDYS:0 LISTENING
TCP 0.0.0.0:1028 7ANDYS:0 LISTENING
TCP 0.0.0.0:1029 7ANDYS:0 LISTENING
TCP 0.0.0.0:2048 7ANDYS:0 LISTENING
I am trying to figure out if there is a fairly repeatable way to convert this type of data into an object, such that the properties of the object are the headers in the first row. I know there are a bunch of ways to do this for the output of individual tools using regex, but I am looking for more of a strategy on how to go about solving this, rather than a one-off solution just for diskpart or netstat.
I was trying to figure out how to use Lee Holmes' script up on Poshcode called Convert-TextToObject, but wasn't quite sure where to start.

Have you seen this: http://thepowershellguy.com/blogs/posh/archive/2007/03/24/hey-powershell-guy-how-can-i-parse-a-tab-delimited-file-and-then-save-that-as-a-comma-separated-values-file.aspx It might be what you are looking for.
回答2:
On a strategical point of view, I would try to transform your text file into a correct CSV (coma separated values) file and then use Import-Csv.
回答3:
I did this yesterday :). You can use out-datatable to transform your data into a System.DataTable. Get it at poshcode.
For more details, see my recent entry.

Something for the netstat example:
get-content netstat.txt | select -skip 1 |
ConvertFrom-String -propertynames blank,proto,local,foreign,state |
select * -ExcludeProperty blank
proto local foreign state
----- ----- ------- -----
TCP 0.0.0.0:80 7ANDYS:0 LISTENING
TCP 0.0.0.0:135 7ANDYS:0 LISTENING
TCP 0.0.0.0:443 7ANDYS:0 LISTENING

Using this ConvertFrom-SourceTable cmdlet:
$DiskPart | ConvertFrom-SourceTable -Literal | Format-Table
Disk ### Status Size Free Dyn Gpt
-------- ------ ---- ---- --- ---
Disk 0 Online 136 GB 0 B
Disk 1 Offline 136 GB 136 GB
Disk 2 Reserved 1027 MB 0 B *
Disk 3 Reserved 500 GB 0 B *
Disk 4 Reserved 500 GB 0 B *
...
$NetStat | ConvertFrom-SourceTable -Literal | Format-Table
Proto Local Address Foreign Address State
----- ------------- --------------- -----
TCP 0.0.0.0:80 7ANDYS:0 LISTENING
TCP 0.0.0.0:135 7ANDYS:0 LISTENING
TCP 0.0.0.0:443 7ANDYS:0 LISTENING
TCP 0.0.0.0:445 7ANDYS:0 LISTENING
...
(This also means that you can also do a full round trip on the above display results)
