I am working in support of an old project of vb.net project. In that large project there are lots of place where 3d,4d array has been used. I want to find out all these files where 3d,4d array has been used. Is there any easy way to find all those at a time. I have tried using regular expression .*\(.*\,\s.*\,\s.*\) for 3d array during searing but its returning nothing.
ter(A, R, P) this is sample 3d array[a,r,p are integer variables]
I know the function with 3 arguments also have also same pattern but its can decrease my task to some extent. What would be best way to solve this problem??thanks in advance

Solution 1

The reason is that , is not to be escaped. So \, is interpreted as \ and , characters separately hence the required match is not found.

Further .* in start is not necessary and \s* is also not necessary as . matches white space too. So the following pattern can be used
\(.*,.*,.*\)
but this matches (A, R, P, S) (A, R, P, S, T) etc. as by default the * quantifier is greedy quantifier and the lazy quantifier *? is not available in Visual Studio. So to exclude , in the search pattern the following pattern can be used

\([^,]*,[^,]*,[^,]*\)

its working now but it is also returning a(),a(1,2) .I want to find out only the 3d and 4d array. Is there any option to avoid those unwanted results.

Then it is better to use the following pattern
\([A-Za-z0-9]+,[A-Za-z0-9]+,[A-Za-z0-9]+\)

the pattern doesn't matching with f(a, b_1, c_34) ..Most of array declaration like this.

But strangely its returning 0 results. I am really confused, may be I am doing some mistake.

Rounak Hasan 21-May-12 2:04am

I have changed it to \([A-Za-z0-9]+[_]*[A-Za-z0-9]*,\s[A-Za-z0-9]+[_]*[A-Za-z0-9]*,\s[A-Za-z0-9]+[_]*[A-Za-z0-9]*\)
But still its returning nothing.

Try
\([^,()]+,[^,()]+,[^,()]+\) or
\([A-Za-z0-9_]+,[A-Za-z0-9_]+,[A-Za-z0-9_]+\)

it also returning zero result. May be because of the space after the comma. I have tried giving /s there but still no result there. And one thing for array declaration it is like
Dim f(a, b_1, c_34) as string
I think by this we can distinguish between calling function with 3 arguments with 3d array.

I have checked.
The first pattern
\([^,()]+,[^,()]+,[^,()]+\)
matches the above array string and with introduction of a space inside [ ]
\([ A-Za-z0-9_]+,[ A-Za-z0-9_]+,[ A-Za-z0-9_]+\)
the second pattern also matches
Please try
Thank you.
