✅ Get instance name inside of class

So i have class like this:

private class CliFlag
{
  public object Value { get; }
  public CliFlag(object value)
  {
    this.Value = value;
  }
}

private class CliFlag
{
  public object Value { get; }
  public CliFlag(object value)
  {
    this.Value = value;
  }
}

and i want to create

ToString

ToString

that will return

-[nameOfTheCliFlag] [valueOfTheFlag]

-[nameOfTheCliFlag] [valueOfTheFlag]

like this

var flag = new CliFlag("x");
flag.ToString(); // -flag x

var flag = new CliFlag("x");
flag.ToString(); // -flag x

however i can't find o way to get the name of the current instance inside of the class, i thought about

nameof(this)

nameof(this)

, but that doesn't work
is there any way how to get this working without passing the name of the flag from outside?

That's not even the name of the current instance. That's the name of the variable to which the current instance is assigned

fair

And no, there's no way to find that. Your instance might not even be assigned to a variable: it might be stored in a list, or simply be an expression.

Also variable names are lost at compile time

ok, i guess that makes sense, thanks for help, i will try different approach here

store the name alongside the value
