From the comments on my other answer, your problem is that you are expecting SVN to recursively search every subdirectory for files matching a wildcard pattern. SVN does not do this. SVN relies on your shell to expand wildcards.
The solution depends on your situation.
If all files you want to commit are in the same common directory, simply cd path/to/common/dir and commit as you are doing (but leave out the comma). You can commit from anywhere within your working copy, but when you do, only the files in that directory tree will be committed.
If you have multiple directories to commit it gets more complicated, depending on what OS you are running on.
Unix-like systems have a ** wildcard meaning "0 or more directory paths", so this should work on Linux or Unix:
svn commit **/*.aspx **/*.aspx.cs -m "message"
Windows doesn't understand the ** wildcard, so you need to specify each on the command line. For example (backslashes for path separators, since I'm assuming Windows here):
svn commit subdir1\*.aspx subdir1\*.aspx.cs subdir2\*.aspx subdir2\*.aspx.cs -m "message"
If you have too many subdirectories for this, simply create a file listing all the files you want to commit, and use that for your file list:
dir /B /S *.aspx *.aspx.cs > file_list.txt
svn commit --targets file_list.txt -m "message"
This last example should also work on Unix-like systems, if you don't like using the ** wildcard (using ls or find with appropriate options instead of dir). It will also let you edit the commit list if you like, before committing, by modifying file_list.txt before you commit.
Edit: Rather than a file, you could make use of a "changelist" to store file names to commit. See the other answers for how to build a changelist.
svn commit. The "possible duplicate" listed is forsvn mv. I don't think that's a duplicate.svn addthem first).
