Define private properties in C# like Typescript

Question

Is there a syntax in C# that allows me to define a private property, like in Typescript?

Example: Typescript:

constructor (private field1: string) { }

In C# I have to do this:

private readonly string field1;
public MyClass(string field1)
{
    this.field1 = field1;
}

update 1:

I'm looking for a syntax sugar for AspNet core dependency injection.

Answer 1

There is no syntactic sugar for this in C# 7, you'll have to write the boilerplate.

Sounds like primary constructors are sort of what you're looking for - they were in C# 6 beta but ultimately dropped.

Answer 2

Class myClass
{
  private string field1 {get; set;}

  public Class()
  {
  }
}

Thats it, you now have a property if you initialize this class. If you want it readonly, only write a get method.

EDIT (after question edit)

If you want a dependency injection syntactic sugar in the constructor as in Angular, unfortunately there aren't any ... yet .

To declare a private field in a class:

Class myClass
{
  private string field1;

  public Class()
  {
  }
}

if you want to be able to initilialize this field with a constructor call, you can give a parameter to the constructor so it can initialize it.

Class myClass
{
  private string field1;

  public Class(string field1)
  {
      this.field1 = field1;
  }
}

you can also define it as a property instead of a simple field (properties have getter and / or setters, and are internally backed by a hidden variable in C# with the below syntax) :

Class myClass
{
  private string Field1 { get; set; }

  public Class(string field1)
  {
      this.Field1 = field1;
  }
}
