WinForms Data Passing: Best Methods

There are various methods available in WinForm application for transferring data between different forms, with popular options including:

1. Passing parameters to the constructor: Data can be passed by passing parameters when instantiating a new form.
2. Passing property values: Assign values to the properties of a new window before opening it, and then read these property values in the new window.
3. Static variable or property: Define a variable or property in a public static class, and then set and retrieve the value of this variable or property in the form where data needs to be passed.
4. Delegate or Event: Define a delegate or event in the parent form, then register this delegate or event in the child form, and pass data by triggering the delegate or event.
5. Global variables or application states: they can be used to store data and share it between different forms.

Using the above methods, it is easy to achieve data transmission between WinForm windows. The specific method chosen depends on the specific application scenarios and requirements.
