Question

从昨天开始，我已经对谷歌进行了相当多的谷歌搜索，但是没有发现它有多大意义。我有一个文件，其中包含应用程序的设置，我认为正确阅读，但更改我的背景颜色的代码可能不是。

我正在尝试根据设置文件文件中的信息更改用于窗口背景的颜色。

窗口代码

<Window x:Class="WindowFrame.MainWindow" Name="WindowFrame"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="WindowFrame" 
    ResizeMode="NoResize" 
    ShowInTaskbar="False" 
    Topmost="True" 
    Focusable="False" 
    IsHitTestVisible="False" 
    AllowsTransparency="True" 
    WindowStyle="None" 
    Width="{DynamicResource {x:Static SystemParameters.VirtualScreenWidthKey}}" 
    Height="{DynamicResource {x:Static SystemParameters.VirtualScreenHeightKey}}" 
    HorizontalAlignment="Center" 
    VerticalAlignment="Center" 
    Background="#7FAC0000" 
    WindowState="Maximized">
<Grid>

</Grid>

        [DllImport("user32.dll")]
        static extern int SetWindowLong(IntPtr hwnd, int index, int newStyle);

        public MainWindow()
        {
            InitializeComponent();
            string filePath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "settings.txt");

                            {
                                contentColor = contentArray[i].Replace("title: ", "");

                                if(contentColor == "light")

                                    WindowFrame.Background = brush;
                                }
                            }

                            if (contentArray[i].ToLower().Contains("intensity: "))
                            {
                                contentIntensity = contentArray[i].Replace("intensity: ", "");
                            }
                            break;
                        }
                }
            }
        }

        public static class WindowsServices
        {
            const int WS_EX_TRANSPARENT = 0x00000020;
            const int GWL_EXSTYLE = (-20);

            public static void SetWindowExTransparent(IntPtr hwnd)
            {
                var extendedStyle = GetWindowLong(hwnd, GWL_EXSTYLE);
                SetWindowLong(hwnd, GWL_EXSTYLE, extendedStyle | WS_EX_TRANSPARENT);
            }
        }

        protected override void OnSourceInitialized(EventArgs e)
        {
            base.OnSourceInitialized(e);
            var hwnd = new WindowInteropHelper(this).Handle;
            WindowsServices.SetWindowExTransparent(hwnd);
        }
    }
}

我相当确定第42行和第65行之间的代码实际上是正确读取文件，但如果不是，请告诉我。

正在阅读的文件如下所示：

color: light
intensity: 1
