将颜色定义为静态变量 [英] Defining color as static variable

问题描述

您好。我想制作一个按钮，可以改变我的应用程序中所有背景网格的颜色。



我只知道这个函数改变了实际网格的颜色：

Hello. I would like to make a button which can change color of all background grids in my app.

I just know that this function changes color of actual grid:

LayoutRoot.Background = new SolidColorBrush(Colors.Blue);

现在，如何将此颜色值存储为静态值？我的意思是，点击后，颜色值将被存储。



如何在每个新页面加载时检索此值？



如何将此值存储在隔离存储中？



我知道我应该使用静态变量创建一个类。

我是编程的新手，所以有人可以告诉我如何编程页面，按钮将放在哪里和class.vb页面？

也许听起来很奇怪，但我根据例子了解一切。

Now, how to store this color value as a static value? I mean, after click, color value will be stored.

How to retrieve this value while every new page loads?

How can I store this value in isolated storage?

I know I should make a class with a static variable.
I am newbie in programming, so can someone tell me how to program page, where button will be placed and class.vb page?
Maybe it sounds weird, but I understand everything better basing on examples.

推荐答案

第一： - 使一个函数生成随机颜色

1st:-Make a function to generate random color

Private Function CreateRandomColor() As Color
    Dim randonGen As New Random()
    Dim randomColor As Color = Color.FromArgb(randonGen.[Next](255), randonGen.[Next](255), randonGen.[Next](255))

    Return randomColor
End Function

Imports System.Windows.Media
Partial Public Class Settings
    Inherits PhoneApplicationPage

    Public Sub New()
        InitializeComponent()
    End Sub

    Private Sub Button1_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button1.Click
Dim color As Color 
color= CreateRandomColor()
 While (color != White or Red or Blue or Green) ''Specify color names u want 
        LayoutRoot.Background = New SolidColorBrush(color)
color = CreateRandomColor()
End While
    End Sub
End Class
