在C＃wpf格式中，我想从外部类更改控件的属性（如button.visible = false）。 [英] In C# wpf form, I want to change the properties of the control (like button.visible=false ) from outside class.

问题描述

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            Form1 fname = new Form1();
            myclass.myctls(fname);
        }
    }
}

我的另一个班级

my another class

namespace WindowsFormsApplication1
{
    class myclass
    {
        public static void myctls(Form f1)
        {
            foreach (Control tempCtrl in f1.Controls)
            {

                    tempCtrl.Enabled = false;
            }
        }
    }
}

推荐答案

不要。让类包含控件来做它。这样，您可以在不影响外部世界的情况下更改表单。

具体如何操作取决于类之间的关系，但其中一个应该有所帮助：

在两种表格之间传递信息，第1部分：父母对儿童 [ ^ ]

在两个表格之间传递信息，第2部分：儿童到家长 [ ^ ]

在两个表单之间传输信息，第3部分：儿童与儿童 [ ^ ]

示例是Winforms，但原则（实际上相关代码）在WPF中是相同的。

Don't. Let the class containign the control do it. That way, you can change the form without affectign the outside world.
Exqactly how you do it depends on the relation ship between the classes, but one of these should help:
Transferring information between two forms, Part 1: Parent to Child[^]
Transferring information between two forms, Part 2: Child to Parent[^]
Transferring information between two forms, Part 3: Child to Child[^]
The examples are Winforms, but the principle (and indeed the relevant code) is the same in WPF.
