Override .ToString method c#

Question

Okay, so I wrote this program out of the exercise of a C# programming book (I\'m trying to learn here) and it asks for \"Override the ToString() method to return all

Answer 1

You are returning a string that just says the phrase _name + _number + _date + _salary.

What you likely wanted to do is build a string using those fields. If you wanted them all mushed together Concat would work, but it would be highly un-readable

public override string ToString()
{
    return String.Concat(_name, _number, _date, _salary);
}

However what would be better is to use Format and include labels with the values

public override string ToString()
{
    return String.Format("Name:{0}, Number:{1}, Date:{2}, Salary:{3}",_name, _number, _date, _salary);
}

If you are using C# 6 or newer you can use the following cleaner format

public override string ToString()
{
    return $"Name:{_name}, Number:{_number}, Date:{_date}, Salary:{_salary}";
}

Which is the exact same logic as the previous String.Format version.
