However it returns an object. This particular method will throw if any error occurs in its parameters.   and useful. Please study the given code and experiment. To master any programming concept you should write your own programs and use them.



Once you're ready to move to the next level you can take this advanced course to learn more in-depth techniques. The class library provides multiple classes to store homogeneous same type or heterogeneous different types data collections.
