C#开发实例-订制屏幕截图工具（六）添加配置管理功能详解（图文）

添加设置窗口

在解决方案资源管理器窗口中，右键单击项目名称，在弹出的菜单中选择：添加》Windows窗体：

输入窗体名称“frmSetup”：

设置窗体的Text属性为“设置”，设置窗体的Size为“472, 276”，StartPosition属性为“CenterScreen”。

添加设置标签页：

左侧工具箱》窗器：双击“TabControl”

设置的Dock属性为“Top”，Size属性为“456, 200”；

添加标签页：

添加三个标签页，Text分别设置为“基本设置，自动上传，自动保存”

添加确定和取消按钮；

基本设置标签页：

从工具箱中添加两个GroupBox，分别为“热键、截图选项”；

添加两个RadioButton，用于热键选择；

添加四个CheckBox用于截图选项；

添加两个TextBox用于设置放大镜的尺寸；

添加两个PictureBox用于显示X和锁的图片；

添加图片资源：

双击Properties中的“Resources.resx”

切换到图像视图：

将图片复制，粘贴到这里，分别命名为“Lock，X”；

设置PictureBox的Image属性为对应的资源：

自动上传标签页：

自动保存标签页：

其中文件名称需要使用两个ComboBox，Items集合分别设置为：

编写代码：

双击设置窗体，切换到代码视图，添加私有变量：

        /// <summary>
        /// 保存Form1的句柄
        /// </summary>
        private IntPtr frm1Handle = IntPtr.Zero;

修改构造函数：

        /// <summary>
        /// 构造函数
        /// </summary>
        /// <param name="frm1_Handle"></param>
        public frmSetup(IntPtr frm1_Handle)
        {
            InitializeComponent();
            this.frm1Handle = frm1_Handle;
        }

为托盘菜单中的设置添加事件处理

打开主窗体Form1的设计视图，选中“contextMenuStrip1”

修改设置菜单的Name为“tsmi_Set”，双击设置菜单，添加代码：

        /// <summary>
        /// 托盘菜单设置事件处理程序
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void tsmi_Set_Click(object sender, EventArgs e)
        {
            frmSetup frm = new frmSetup(this.Handle);
            frm.ShowDialog();
        }

编译，调试一下，通过托盘图标的右键菜单》设置 可以打开刚刚添加的设置窗口了。

添加项目引用：

主窗体添加相关配置项变量：

        #region 基本设置参数
        /// <summary>
        /// 截图时是否显示截图信息栏
        /// </summary>
        public bool InfoBoxVisible = true;
        /// <summary>

        public int ZoomBoxWidth = 120;
        /// <summary>
        /// 放大镜的尺寸——高度
        /// </summary>
        public int ZoomBoxHeight = 100;
        #endregion

        #region 图片上传参数
        public string PicDescFieldName = "pictitle";
        public string ImageFieldName = "upfile";
        public string PicDesc = "cutImage";
        public string UploadUrl = "http://";
        public bool DoUpload = false;
        #endregion

        #region 自动保存参数
        /// <summary>
        /// 是否自动保存到硬盘
        /// </summary>
        public bool AutoSaveToDisk = false;
        /// <summary>

        /// 自动保存文件名序号
        /// </summary>
        public int autoSaveFileIndex = 0;
        #endregion 自动保存参数

添加“AppSettingKeys”类：

    /// <summary>
    /// 提供配置文件中AppSettings节中对应的Key名称
    /// </summary>
    public static class AppSettingKeys
    {
        //基本设置
        public static string HotKeyMode = "HotKeyMode";
        public static string InfoBoxVisible = "InfoBoxVisible";
        public static string ToolBoxVisible = "ToolBoxVisible";
        public static string ZoomBoxVisible = "ZoomBoxVisible";
        public static string ZoomBoxWidth = "ZoomBoxWidth";
        public static string ZoomBoxHeight = "ZoomBoxHeight";
        public static string IsCutCursor = "IsCutCursor";
        //图片上传
        public static string PicDescFieldName = "PicDescFieldName";
        public static string ImageFieldName = "ImageFieldName";
        public static string PicDesc = "PicDesc";
        public static string UploadUrl = "UploadUrl";
        public static string DoUpload = "DoUpload";
        //自动保存
        public static string AutoSaveToDisk = "AutoSaveToDisk";
        public static string AutoSaveSubDir = "AutoSaveSubDir";
        public static string AutoSaveDirectory = "AutoSaveDirectory";
        public static string AutoSaveFileName1 = "AutoSaveFileName1";
        public static string AutoSaveFileName2 = "AutoSaveFileName2";
        public static string AutoSaveFileName3 = "AutoSaveFileName3";

    }

Program.cs文件添加枚举类型：

    /// <summary>
    /// 控制键的类型
    /// </summary>
    public enum KeyModifiers : uint
    {
        None = 0,
        Alt = 1,
        Control = 2,
        Shift = 4,
        Windows = 8
    }

警告：由于xxx是引用封送类的字段，访问上面的成员可能导致运行时异常
