In the previous delegate (Delegate) type, I used the static keyword when I defined the public method, resulting in the inability to access this method in the form of an object. Method name, which we will learn to specify static variables. Variable:

This article describes the method of ASP. NET Filter HTML string, for everyone to refer to the use, the specific code is as follows: Remove HTML tags//////// include HTML source removed text public static string getnohtmlstring (String

All I have described above are value types, so much so that I summarize the following what is called value type. Simply put, this type of variable stores the contained values directly. Here we are relative to the C language string, char ch[6] = "HC66

C # Data types The C # language is a strongly typed language that must have a type in the variables, expressions, values, etc. used in the program. For each amount of information stored in the program, we must declare his data type in order for the

When writing the code: IList IList11 =new List (); List List11 =new list (); Some doubts, so search on the internet, very inspired, so the collection, but to some point of view, with the red font mark my Views! First, the IList generic interface

In some cases, we need to read the data from the database to populate the object or read the file from the hard disk to populate the object, but this is relatively time consuming. That's when we think of a copy of the object. In this paper, the use

C # operations Excel data additions and deletions. First create the Exceldb.xlsx file and add two sheets. Worksheet 1: UserInfo table, fields: UserId, UserName, age, Address, Createtime. Worksheet 2: Order table, Fields: OrderNo, ProductName,

What is a singleton mode? Ensure that a class has only one instance and provides a global access point to access it. "DP" Let the class itself be responsible for saving its only instance, which guarantees that no other instance can be created, and

Policy Mode definition: The algorithm family is defined, separately encapsulated, so that they can replace each other, this mode allows the algorithm to change, does not affect the use of the algorithm of the customer. The policy pattern contains

Definition: Specifies the kind of object created with the prototype instance, and creates a new object by copying the prototypes. The prototype pattern is actually creating another customizable object from one object without needing to know the

Template method Pattern: Defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. The template method allows subclasses to redefine some specific steps of the algorithm without altering the structure of an

Iterator pattern: Provides a way to access individual elements in an aggregated object sequentially, without exposing the internal representation of the object. "DP" Four characters: Iterator iterator abstract class: Used to define the starting

Decorative mode: Dynamically add some additional responsibilities to an object, and the adornment mode is more flexible than the subclass to increase functionality. Four characters in decorating mode: Component class: Component Specific Component

The example in this paper describes the method for the conversion of a DataTable in C #. Share to everyone for your reference. The implementation method is as follows: protected void Page_Load (object sender, EventArgs e) {if (! IsPostBack)

public class User {public int ID {get; set;} public string Name {get; set;}} Corresponding database table://user//field: ID, Name Then you may need to write a method that transforms the DataTable into a solid object, which
