Toolkit

.NET Toolkit is a tool for simplify the development of classes, business logic, UI elements, etc.

Toolkit

• Contracts - a way to verify the transferred parameters in a concise way. Contracts are intended to replace the cumbersome constructions of condition checks, such as:

  if (string.IsNullOrWhiteSpace(str?.Trim()))
  {
      throw new Exception("The value is incorrect");
  }

  Instead, just write:

  Contract.StringFilled<Exception>(str);

  The same goes for null checks:

  Contract.NotNull<object, ArgumentNullException>(obj);

  Logic checks:

  Contract.MoreOrEqualThan<int, InvalidOperationException>(first, second);

• Check - a static class similar to the Contract class, but returns a Boolean value instead of throwing an exception.

  if (Check.NotNull<object>(obj)) // true if obj isn't null

  String checks:

  string str = "";
  if (Check.StringFilled(str)) // false because str is empty

• Condition - allows you to build a chain of logical conditions.

  int a = 10;
  int b = 20;
  var result = Condition
               .Check(a == 10)
               .And(b == 20);
               .Or(b == 5)
               .Not() // now it's false

Toolkit.Components

• BaseViewModel contains an implementation of the INotifyPropertyChanged interface with the OnPropertyChanged() method to notify observers about a change in the value of the observed object.

  The generic SetProperty method is designed to assign values to observable objects and notify about their change.

• IMessage is an interface for solving the problem of calling a dialog from a ViewModel without interacting with the View layer.

  // View layer
  public class Message : IMessage
  {
      public void Report() { MessageBox.Show("Message for user" );
  }
  
  public MainWindow()
  {
      DataContext = new ViewModel(new Message());
  }
  
  // ViewModel layer
  class ViewModel
  {
      public ViewModel(IMessage message)
      {
          message.Report();
      }
  }
