Figure 1. C# demo code
"C# is designed to be a platform-neutral language, a workhorse for cross-platform applications."
- Anders Hejlsberg, creator of C#
There are four ways of viewing CSharp content in this site:
  1. CSharp Story
    An ebook with seven chapters that covers CSharp programming at intermediate level.
  2. CSharp Bites
    A large collection of pages each focused on one feature of the CSharp programming language, starting with basics.
  3. Blogs
    There are now, as of 07 Jan 2025, no C# blogs. That is expected to change eventually.
  4. dotnet fiddle Playground code examples
It's easy to sample each of these views by using the links above, or more selectively, using links in the C# Explorer's panel on the left. The code above on the right illustrates a CSharp "ShowType" function, useful for evaluating library and user-defined types.
Everything below this line is a place-holder for content to come.

Exercises

  1. Write a CSharp program to find the largest file in a specified directory tree, using walkdir crate from crates.io.
  2. Ammend Project #1 by accepting arguments from the command line, using args crate.
  3. Use ChatGPT to create a directory traversal crate and use that instead of walkdir.
  4. Write a CSharp program to read a source code file and count the number of lines and number of scopes for each function. You can count scopes by counting open braces "{". Start by searhing for fn and then read each line searching for "{" and "}". Push each open brace on a stack, and pop when a closed brace is encountered. When the stack is empty, the end of the function has been reached.
  5. Modify Project #4 by counting lines and scopes for each file in a directory tree rooted at a specified folder, usually named "src".
