object of affection is in reflection

This example shows that C # uses reflection to determine whether an object contains an attribute, and for C # program designers, it has a certain learning value.The specific implementation code is as follows:Here's how to use the code:bool cc = _person. Containproperty ("CC"); bool AA = _person. Containproperty ("Age");I hope that the examples described in this a

In webform, you can use reflection to bind a business object to an ASP. NET form control. For more information about the winform project, seeCodeImplement the same function. Winform does not provide the findcontrol method similar to webform, so I wrote a method similar to webform in the way of traversing the control, considering that many of the winform controls are placed in label and tabcontrol, the met

Java reflection (1): Get the Class Object The entrance to all reflection operations is java. lang. Class. Except java. lang. reflect. ReflectPermission, no class under the java. lang. reflect package has a common constructor. To obtain these classes, it is necessary to call

We usually use Sharedpreferences to store some data that needs to be saved locally, but not stored in the database, generally we use it to store some user names, passwords and other data is very convenient, then if we want to store information there are 10 of several, We have to write 10 lines of repetitive code to put them in, take out the time also have to write 10 lines of code to remove them one by one, then there

We usually use Sharedpreferences to store some of the needs to be saved locally. But not some data stored in the database. Generally we use it to store some username,password and other data is very convenient, then assume that we want to store information there are 10 of several. We have to write 10 lines of repeated code to put them in. When you take it out, you have to write 10 lines of code to take them out of one piece, so

We know that the JS engine of all browsers gets this object at one time when for in reflects a member of an object, for example VaR OBJ = {A: 1}; For (VAR o in OBJ) {OBJ = {A: 1, B: 2 };} The entire for loop will only be executed once. We recycle the reference of OBJ internally, but the reflection object

): self.name = name def eat (self, food): print ('%s is eating% S "% (self.name, food)) d = Dog (" Tom ") Choice = input (" >>>: "). Strip () SetAttr (d, Choice, ' Apple ') # Food, So it's equivalent to D.food = ' Apple ' # print (D.food) so it's dead, or with one of the following print (GetAttr (d, choice)) # output # >>>:food# AppleIv. delattr (x, y)Function: Delete the property or method in the Obj

reference or pointer to the derived class object, you can get the use of concise, Consistent external interfaces enable the benefits of a colourful and cluttered inner execution logic .If the 2nd makes you think abstract is not intuitive, I will give a specific example of life you can immediately understand the benefits of polymorphism. For example plug plug, electrical plug of the number of appliances, th

① What is reflection?Reflection provides encapsulated assembly, module, and type objects.You can use reflection to dynamically create instances of the type (see figure 4), bind the type to an existing object (this does not exist), or obtain the type from an existing
