I work in illustrator but my client needs file in coral draw how can i convert an .ai (adobe illustrator) file to .cdr (Coral Draw file)
You can't. But Corel Draw CAN import AI, EPS and PDF files.
HOWEVER; all effects like gradients, drop shadows and the like will be rasterized -- they will no longer be editable. Also, any multi-line text may be broken apart into individual chuncks.

I do not completely agree with that statement. Draw's .ai import filter has been pretty smart for a long time.
For example, Illustrator gradient fills are usually converted to editable gradient fills in Draw. Even Illustrator gradient mesh objects can be imported as Draw's equivalent mesh objects, still editable.
