The previous code is a LINQ self-inferred type. In fact, LINQ at the end of the query is able to create types dynamically. varIntarray =New[] {1,2,3,4,5,6,7,8,9,Ten, One}; varList = fromNuminchIntarraywherenum >1&&num5Let l=array.indexof

Direct to the code bar, so simply direct, also do not delay my lunch break. Everything is in the source code. Public classcontroleventtool{/// ///remove a class of events from a control, such as the Click event///2018.3.21/// Public Static

For a class, if it is defined (as Object a) and another object B is assigned directly ("a = B") to it, it is equivalent to assigning the address to the object. When another object B is no longer applied to this address, a the point of the stack

A delegate is a class that defines the type of the method so that the method can be passed as a parameter to another method. An event is a special kind of delegate.1. Declaration of DelegationDelegate classDelegate is a reference type, we treat him

1. C # encapsulates all the basic types into its own type, for example, int is encapsulated into a struct structure. If you define an int object, you can call the function in the INT structure.2, unlike c\c++, C # char is simply representative of
