This bee upgrade to the 1.5 version, in the execution of bee version will be output a color Bee logo, many people feel very magical, in fact, this is the ANSI color code. In fact, in Linux, we write C language easily can achieve this effect. The specific writing format is as follows: 格式：\033[显示方式;前景色;背景色m 说明：前景色 背景色 颜色-----------------------------

Metadata is tag information in the: NET assembly. It is in the code to choose to go to the definition of the time to locate it. Because the source code was not found, vs read the information in the metadata by reflection to generate that. Workaround: 1. To add the project to the solution first. 2. Then refer the added item to the website (right click on the site,

Recommendation 151: Replace the exposed event member variables with event accessorsEvent accessors contain two parts: add accessors and delete accessors. You should always use event accessors if you are involved in a public event field. The code looks like this: class SampleClass { new eventhandlerlist (); Public Event EventHandler Click { add { events.} AddHandler (null, value);

following naming convention:Delegate variable owning object +on+ delegate variable nameAs follows: Public BOOL Nameonvalidatevalue (object value) { } publicvoid Nameonpropertychanged (DependencyObject D, DependencyPropertyChangedEventArgs e) { }Name of the failure: Public void namechanged (DependencyObject D, DependencyPropertyChangedEventArgs e) { }This name should look more like a delegate o

Recommendation 99: Overriding should not use child class parametersWhen overridden, if a child class parameter is used, it may deviate from the designer's intended target. For example, there is an inheritance system as follows: class Employee { } class manager:employee { }The Setsalary method in type Managersalary now overrides the same method in salary, and the overridden method takes a subclass parameter: class Salary { publicvoid setsalary (Employee e)

collection initialization setting, the compiler calls the Add method on the collection after the collection object has been created.The above code demonstrates how to create a new object or an existing object in an initialization statement, as well as a null value.However, initializing the settings is not only convenient for object and collection initialization, the properties of the anonymous type in the collection returned by the LINQ query are rea

Recommendation 64: Increase the tester-doer mode for loops instead of placing the try-catch inside the loopIf you need to throw an exception in a loop, you need to be particularly careful that throwing an exception is a fairly performance-impacting process. You should try to judge some of the conditions of the anomaly in the loop and then process it according to the conditions.Do a test:Stopwatch Watch =stopwatch.startnew (); intx =0; for(inti =0; I 10000; i++) { Try
