C# Example

First, generate C# code that can read and write the data types defined in “students.tcks”:

> cks gen-c# students.tcks Example.Students gen/Students.hs

The “Example.Students” is the C# namespace that the generated classes will be assigned. The “gen/” is the directory that the generated files will be written to.

Example use of generated bindings:

using Example.Students; // the generated classes

using Cks.Data;
using BinaryFormatException = Cks.Binary.Reader.BinaryFormatException;

using Console = System.Console;
using System.IO;

public class AddShaggy
{
  public static void Main(string[] Args)
  {
    if (Args.Length != 1) {
      Console.Error.WriteLine("Expecting exactly one argument.");
      return;
    }
    string Path = Args[0];

    // Read in the list of students.
    List<Student> Students = Read(Path);
    if (Students == null) System.Environment.Exit(1);

    // Append Shaggy to the list.
    Student Shaggy =
      new Student("Shaggy Rogers", 42, new Sex.Male_());
    Students.Add(Shaggy);

    // Write the updated list out to the same file.
    Write(Path, Students);
  }

  public static List<Student> Read(string Path)
  {
    FileStream fs = File.OpenRead(Path);
    using (BinaryReader In = new BinaryReader(fs)) {
      try {
        // The main API call to read CKS data.
        return Students._BinaryReader.Read(In);
      }
      catch (BinaryFormatException e) {
        Console.Error.WriteLine("Format error: " + e.Message);
        return null;
      }
    }
  }

  public static void Write(string Path, List<Student> Value)
  {
    FileStream fs = File.Open(Path, FileMode.Create, FileAccess.Write);
    using (BinaryWriter Out = new BinaryWriter(fs)) {
      // The main API call to write CKS data.
      Students._BinaryWriter.Write(Out, Value);
    }
  }
}
