Directly access the value of the intermediate variable in the intermediate variable of the public attribute

Define an intermediate variable for public attributes...

ls can,
If there are many parameters passed, use delegate

If it is a dialog box, you can enter the middle variable
public string textbox1text
{
get
{
return textbox1.text
}
}

If there are multiple, you can also define a data structure or class
Used to pass parameters

There are multiple methods for assigning controls between forms:
1. Use event delegation
2. Change the private declaration of the form control to public,
   Take one form as the parent form and the other as the child form, you can set the control value of the child form in the parent form
3. If it is accessed when it is loaded, it is directly passed as a parameter in the form constructor.
4. Write a class, define static properties or methods (set and get),
   Can assign values ​​in one form, get values ​​in another form
