问题描述

如何从一种形式(settings.form)更改所有其他形式的背景颜色?我想发展我的毕业设计.它是一个社交媒体桌面管理项目.我想用一个切换器将所有形式更改为暗模式.我怎样才能做到这一点?这是我的settings.cs

How can we change the background color of all other forms from one form (settings.form)? I want to develop my graduation project. Its a social media desktop management project. I want to change all of the forms to dark mode with one switcher. How can I do that? This my settings.cs

public void checkBox1_CheckedChanged(object sender, EventArgs e)
{
    if (checkBox1.Checked)
    {
        panel1.BackColor= Color.FromArgb(34, 36, 49);
        form1.BackColor = Color.FromArgb(34, 36, 49);
        form2.BackColor = Color.FromArgb(34, 36, 49);
        this.BackColor = Color.FromArgb(34, 36, 49);
        this.label1.BackColor = Color.White;
        this.label1.ForeColor = Color.FromArgb(34, 36, 49);
    }
    else
    {
        this.BackColor = Color.White;
        this.label1.BackColor = Color.FromArgb(34, 36, 49);
        this.label1.ForeColor = Color.White;
    }
    form1.Show();
    form1.Refresh();
    form2.Show();
    form2.Refresh();

当我切换时，所有背景颜色都在变化.但是所有形式都同时开放.

All background color is changing when I switch. But all forms is opening sametime.

推荐答案

您可以使用(ApplicationSettings)属性，该属性可从表单设计器"的Properties面板访问.展开ApplicationSettings，打开PropertyBinding对话框，将设置添加到BackColor属性(例如，CommonFormBackColor)，并对所有表单使用相同的设置.

You can use the (ApplicationSettings) property, accessible from the Form Designer's Properties panel. Expand ApplicationSettings, open up the PropertyBinding dialog, add a Setting to the BackColor property (e.g., CommonFormBackColor) and use the same setting for all Forms.

您可以直接在应用程序设置"的PropertyBinding对话框中创建设置:

You can create the Setting directly in the Application Settings' PropertyBinding dialog:

此新设置是在用户范围中创建的.
用户范围中的所有设置都是按用户应用的，可以更改.
应用程序范围"中的设置被认为是只读的.

This new Setting is created in the User Scope.
All settings in the User Scope are applied on a per-User basis and can be changed.
Settings in the Application Scope are considered read-only.

新设置将出现在ApplicationSettings可扩展属性下:

The new Setting will then appear under the ApplicationSettings expandable property:

为所有更改此设置后应更改其BackColor的窗体分配相同的设置.
当然，您可以将通用设置分配给任何其他控件的任何其他属性.

Assign the same Setting to all Forms that should change their BackColor when this setting is changed.
You can of course assign a common Setting to any other Property of any other Control.

使用

The use of a Form Template (or a base Form class) can automate the whole process.

在运行时更改设置"值时，所有打开的窗体以及以后将打开的窗体都将显示相同的BackColor.

When the Setting value is changed at run-time, all opened Forms - and those that will be opened later - will present the same BackColor.

您可以为所有窗体的BackColor设置一个新值，以更改设置的值:
_{(所有打开的共享BackGround Color相同设置的表单将立即更改颜色)}

You can set a new value to all Form's BackColor changing the Settings's Value:
_{(all opened Form that share the same Setting for the BackGround Color will change color immediately)}

Properties.Settings.Default.CommonFormBackColor = Color.Orange;

您可以使用以下命令保存当前的设置"选择(以保留在当前会话中分配的值，以便在应用程序重新启动时再次使用该值):

You can save the current Settings selection (to preserve the value assigned in the current session, so it will be used again when the application is restarted) with:

Properties.Settings.Default.Save();

您可以重置默认值(最初分配给设计器中设置"的值)，调用:

You can reset the default value (the value originally assigned to the Settings in the Designer) calling:

Properties.Settings.Default.Reset();
