Use of the indexer in Asp. Net and asp.net
The indexer definition is similar to an attribute, but its functions and attributes are different. the indexer provides a special method for writing get and set accessors. the attribute can access the data of an object like an access field, and the indexer can enable users to

1, get accessor return value. The set accessor assigns a value.2, this keyword is used to define indexers.3, the value keyword is used to define values that are assigned by the set indexer.4. Indexers do not have to be indexed based on integer values, and you decide how to define a specific lookup mechanism.5, indexers can be overloaded.6. Indexers can have multiple formal parameters, su
The indexer allows instances of classes and structures to be indexed in the same way as arrays. The indexer is similar to an attribute. The difference is that their accessors use parameters. It is called the property with parameters.Simple indexer instance:Class Program{Static void Main (string [] args){IndexClass a = new IndexClass ();A [0] = "Chen San ";A [1] =
Indexers are a special class member that allows objects to be accessed in an array-like manner, making the program look more intuitive and easier to write.1, the definition of the indexerClass members in C # can be any type, including arrays and collections. When a class contains arrays and collection members, the indexer greatly simplifies the access operations of an array or collection member.You define indexers in a way that is similar to defining
The indexer (C # programming guide) in the interface can be declared on the interface (C # reference. The accessors of the interface indexer are different from those of the class indexer in the following aspects: the interface accessors do not use modifiers. The interface accessor has no body. Therefore, the accessors are used to indicate whether the

An indexer allows an instance of a class or struct to be indexed in the same way as an array, with an indexer similar to an attribute, unlike an indexer whose access is a parameter. Declarations are somewhat similar to attributes. The indexer

Yesterday, a friend asked me how to use the indexer in C # and explained it to him. If you ask other people, the answer will not be used. Obviously, because I think the indexer is not commonly used, I forgot it. In fact, we often use the indexer: array [I] when accessing arrays and set elements. when you access the datagridview and gridview: gridview. datakeys [I
An indexer (Indexer) is a new class member introduced by C # that makes an object as convenient and intuitive as an array. Indexers are very similar to the properties mentioned earlier, but indexers can have argument lists and can only act on instance objects, not directly on the class. The following is the design of a typical indexer, where the specific implemen

BackgroundIn some applications, the interface needs to be bound to the indexer and updated in real time as the value changes.Solution SolutionsSimply implement the INotifyPropertyChanged interface with the class that contains the indexer and raise the PropertyChanged event when the index value changes, and set the property name to item[].

I recently came into contact with indexer. Generally speaking, indexer refers to something similar to a property defined in a class. The indexer is a new class member in. net. Similar to class attributes. Some people simply call it an attribute with parameters.
The indexer can quickly locate a group member in a class
MyClass (int myval) named "Myval" 8 {9 //"This" represents the current instance of the MyClass class // Here through this can be semantically distinguished member name myval and parameter name myVal11 this.myval + = myval;12 //Use this as an argument to the current object to the Compute method, int res = Myval + myclass1.compute (this); }16 }3. declare the indexer
