Is it suitable to make properties of my customize exception to be set

Question

There is my customize exception class

    public class ParseFailedException : Exception
    {
            public string FailedFileName { get; set; }

            public int? LineNo { get; set; }
            public int? ColumnNo { get; set; }
    }

Is it good make the property as set, or should they be passed through the constructor method?

Answer 1

Just pass the properties through the constructor, and set the 'set' to 'private' for the properties. It should not be possible to change the properties after throwing the exception to ensure accurate and correct information in the object.

Answer 2

It's easier to set by constructor (then You throw Your exception in one line), but reading should be available using properties.

Answer 3

Exceptions are immutable objects and populated by the exception source so there should not be a public setter for your properties.
