Hello ,
I can't write for a long time because of the intensity work.
In my new article , I will talk abbout new features from c# 9.0. New feature are available that make our business easier.
1-Target-typed new expressions
If the object type can be estimated when creating an object, it will no longer be necessary to specify the type before calling constructor. For example :
List<string> list =new List<stirng>();
Here, since the type of object can be estimated from the defination on the left side, it will be possible to use as follows.
List<string> list=new();
2-Prameter null checking
Null control of parameters that will be passed to methods that will be added to the end of the parameter ! it can now be done automatically with the mark.
For example :
public void Work (Person person)
{
if (person == null)
{
thrpw new ArgumentNullException(nameof(person)));
}
}
In this way, instead of checking null, we can make this process automatic by defining it as follows.
public void Work(Person perso !)
{
}
