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.
The preceding actions take place when an instance is created using thenewoperator. If a new instance of astructis set to itsdefaultvalue, all instance fields are set to 0. Elements of an array are set to their default value of 0 ornullwhen an array is created. ...

The base constructor initializes all fields to their default values. The following table shows initial property values for an instance of SqlCommand. 展开表 PropertiesInitial value CommandText empty string ("") CommandTimeout 30 CommandType CommandType.Text Connection Null You can change the value fo...
Use this constructor to initialize a new instance of theCheckBoxFieldclass. This constructor is commonly used when adding fields to a dynamically created data-bound control. To dynamically add aCheckBoxFieldobject to a data-bound control, create a newCheckBoxFieldobject, set its properties, and the...
They’re not entirely functionally equivalent if you have defined your fields as readonly because primary constructor parameters for non-record types are mutable. So, when you’re using this refactoring approach, be aware that you’re changing the semantics of your code. If you want to maintain...

The workaround is to either build your own version of CsWinRt that doesn't generate types with RVA static fields and a class constructor, or build your own version of ILC with the above mentioned line commented out. CsWinRT has other problems with NativeAOT. It will not work in general...
When a struct instance constructor has athis()constructor initializer that represents thedefault parameterless constructor, the declared constructor implicitly clears all instance fields and performs the initializations specified by thevariable_initializers of the instance fields declared in its s...
By default, Mapster will only map to fields and properties. You can configure to map to constructors byMapToConstructor. //global levelTypeAdapterConfig.GlobalSettings.Default.MapToConstructor(true);//type pairTypeAdapterConfig<Poco,Dto>.NewConfig().MapToConstructor(true); ...
