推荐答案

您是说要向Form类本身添加属性?如果是这样，您就不能，但是有两个简单的解决方案.

1.创建一个从Form派生的新类，并在需要时使用它.

Do you mean add a property to the Form class itself? If so, you can''t but there are two easy solutions.

1. Create a new class derived from Form and use that in place when you need it.

public class MyFormBase : Form
{
    // ...
    private int id;

    /// <summary>
    /// Gets or sets the identifier.
    /// </summary>
    public int ID
    {
        get{ return id; }
        set{ id = value; }
    }
}

因此，在添加新表单时，请更改声明

So when adding a new form, change the declaration

public partial class Form1 : MyFormBase
{
    // ...
    // Form1 instances automatically have ID property
}

2.使用扩展方法 [

2. Use Extension Methods[^]

只需添加它即可.如果您在执行此操作时遇到特定问题，请发布代码并进行解释.

Just add it. If you have a specific issue with doing so, post your code and explain it.
