Initializes a new instance of the Object class. C# 复制 public Object (); Remarks This constructor is called by constructors in derived classes, but it can also be used to directly create an instance of the Object class. Applies to 产品版本 .NET Core 1.0, Core 1.1, Core 2.0, Core ...
This example shows how a class is instantiated by using the new operator in C#. The simple constructor is invoked after memory is allocated for the new object.
When you declare an instance constructor in a derived class, you can call a constructor of a base class. To do that, use thebasekeyword, as the following example shows: C# abstractclassShape{publicconstdoublepi = Math.PI;protecteddoublex, y;publicShape(doublex,doubley){this.x = x;this....
Referencing the constructor parameter in an instance member. Every other constructor for a classmustcall the primary constructor, directly or indirectly, through athis()constructor invocation. That rule ensures that primary constructor parameters are assigned anywhere in the body of the type. ...

The issues reported by this rule occur when a class that you implement with virtual methods in its construction sequence is then derived from. If you seal your class, or otherwise know or enforce that your class will not be derived from, the considerations explained here and the issues that ...

Avoids polluting the instance (this) namespace with internal values that can cause issues with inheritence for base/super classes or even derived classes that extend your class. Smaller code as the internal properties and methods when defined within the instance can be minified. ...
