Introduction:? Why do you want to write this? It's just a sudden thought. Let's talk about my current understanding.KVC:? Key-value coding is a mechanism that uses string identifiers to indirectly access object attributes. However, for this reason, I have never realized the benefits of using this feature for so long. I have no obvious reason to use setvalut: forkey instead of directly using an attribute. Of

#. developers can implement query expressions in C # code that resemble SQL statements, thus enabling the functionality of data queries .LINQ does not simply nest query expressions in C #, but rather a query expression as a syntax for C #. A data source accessed by a query expression is a collection object that contains a set of data. As a result, the data type of the query is checked at compile time, enh

What is the essence of @property.@property = Ivar + getter + setter;The following explanation:The property has two major concepts: Ivar (instance variable), access method (access methods = getter + setter).property as an attribute of objective-c, the main function is to encapsulate the data in the object.

enterprises, and the process was just as transparent as a black box. BPM opens the black box of enterprise processes to clearly expose internal work of business processes. With bpm, you can directly view all elements of the process design, including the process model, workflow, rules, systems, and participants. Of course, you can also see real-time performance and even predict performance trends. BPM can directly manipulate the process structure and flow direction, track the results of the proc

"When you see a bird walking like a duck, swimming like a duck, or screaming like a duck, this bird can be called a duck ." We do not care about the object type, whether it is a duck or not, but behavior. For example, in Python, there are many file-like items, such as stringio, gzipfile, and socket. They have many identical methods. We use them as files. Duck type is often used in dynamic languages and

Asp.net 2.0 has a special directory app_data. Generally, the SQL Server 2005 express data file is stored in this directory. The corresponding database connection string is:Connectionstring = "......
