Coming From
When coming from another language it is good to find out where D stands in relation to it. There is the feature list which states if a feature exists or not and possibly an explanation. For a side-by-side comparison of many languages: Languages vs D or you can look at code snippets of from Rosetta Code.
A very superficial way to find out the popularity of D in relation to other languages can is at the Tiobe Index website.

Porting
If you are interested in converting your code to D start by looking at the Porting Overview.
Walter Bright has observed that when you first start writing D you tend to write it like the existing languages you are familiar with. In time you may choose to make use of the higher-level features of D that make writing D code a pleasure rather than a chore. But programming is about using a tool to solve a problem, and there is no dogma in D that there is only one way to do it. Very often you don't need to make use of advanced D features like metaprogramming, templates, and compiler time function execution to achieve a useful result quickly.
So it's often initially satisfying to start by porting the code as is, and then over time refine it or write a higher-level wrapper (you can start by wrapping only a few bits and build up over time).
