参考： https://docs.microsoft.com/zh-cn/visualstudio/ide/visual-csharp-code-snippets?view=vs-2017

 

常用的代码片段：

ctor 自动生成默认的构造函数
prop自动生成get set方法
cw 自动生成Console.WriteLine()
输入override 然后按空格，自动显示父类中所有可重写的成员列表
Exception 自动生成一个新的遵循.NET最佳时间的异常类

 

以下是从visual studio中整理出来的常用代码片段，以作备忘

        {
            get { return (int)GetValue(MyPropertyProperty); }
            set { SetValue(MyPropertyProperty, value); }
        }

        // Using a DependencyProperty as the backing store for MyProperty.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty MyPropertyProperty =
            DependencyProperty.Register("MyProperty", typeof(int), typeof(ownerclass), new PropertyMetadata(0));

快捷键: propa

        public static int GetMyProperty(DependencyObject obj)
        {
            return (int)obj.GetValue(MyPropertyProperty);
        }

        public static void SetMyProperty(DependencyObject obj, int value)
        {
            obj.SetValue(MyPropertyProperty, value);
        }

        // Using a DependencyProperty as the backing store for MyProperty.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty MyPropertyProperty =
            DependencyProperty.RegisterAttached("MyProperty", typeof(int), typeof(ownerclass), new PropertyMetadata(0));

快捷键: wde

用途: Windows工作流模式下创建依赖属性事件的模板

        public static System.Workflow.ComponentModel.DependencyProperty InvokeEvent = System.Workflow.ComponentModel.DependencyProperty.Register("Invoke", typeof(EventHandler), typeof(Obj));

        [System.ComponentModel.Description("Invoke")]
        [System.ComponentModel.Category("Invoke Category")]
        [System.ComponentModel.Browsable(true)]
        [System.ComponentModel.DesignerSerializationVisibilityAttribute(System.ComponentModel.DesignerSerializationVisibility.Visible)]
        public event EventHandler Invoke
        {
            add
            {
                base.AddHandler(Obj.InvokeEvent, value);
            }
            remove
            {
                base.RemoveHandler(Obj.InvokeEvent, value);
            }
        }
