To summarize, C# programming language can be used to build Windows app using the .NET platform, and can also be used to build Linux app using the Mono platform. It cannot be used to make an Android app, but with persistence, in theory, you can wrap it around the Android NDK framework.
Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language used by Apple for the OS X and iOS operating systems, and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch prior to the introduction of Swift. The programming language Objective-C was originally developed in the early 1980s. It was selected as the main language used by NeXT for its NeXTSTEP operating system, from which OS X and iOS are derived.
