How to fix override ToString method


By : randomwalk

around this issue As mentioned in the comments you have declared a method inside another method. You need to move the ComputerPrice() outside of the ToString method. Also, you need to remove the tomatoSlices from the ToString definition:
code :
class Sandwich
{
    public string name = "Tony";
    public string meat = "None";
    public int tomatoSlices = 1;

    public double ComputerPrice()
    {
         return 4.0 + (0.5 * tomatoSlices);
    }

    public override string ToString()
    {
        return ComputerPrice().ToString();
    }
}
var sandwich = new Sandwich();

var price = sandwich.ToString();

How can I override the ToString() method in C#?

will help you As per your question, to change some characters in the ToString implementation, you need to call the existing ToString method by using the base keyword:
code :
public override string ToString()
{
    return base.ToString().Replace("something", "another thing");
}

Override ToString or provide non-ToString named extension method for an interface?

I think the issue was by ths following ,
Would you even consider ToString giving you a useful output on a collection/enumerable type? Would that violate the principle of least surprise?
code :
string result = new string(mySlice.ToArray());

Does Arrays.toString() override Object's toString() method?

this one helps. The Arrays class is a utility class. As it isn't instantiable, Object's toString method is irrelevant.
The static toString methods you see are totally unrelated to the standard toString method, as should be clear from their description in the javadoc. Note also the plural form : there's more than one method with this name and none of them has the same signature as the Object's one : they all take some argument.

like below fixes the issue In ES5 style javascript, to override the toString method I would simply do the following: , This actually does work:
code :
class MyAwesomeClass {
  toString() {
    console.log("toString called");
    return "Awesome";
  }
}

console.log(new MyAwesomeClass() + "!!!");

Implementing ToString does not override the original ToString method despite using Overridable/Overrides. What do I miss

it helps some times I guess, VB's Overridable and Overrides specifiers do not work how I thought they do. , If you call it through the interface, it will work:
code :
Sub Main()
    Dim oTest As IElements = New TestingOverrides("x")
    Console.Write(oTest.ToString())
End Sub
Sub Main()
    Dim oTest As New TestingOverrides("x")
    Console.Write(oTest.IElements_ToString())
End Sub
Public Class Grandfather
    Implements IElements
    Private _MyArg As String
    Public Sub New(Arg As String)
        _MyArg = Arg
    End Sub
    Public NotOverridable Overrides Function ToString() As String _
        Implements IElements.GetArg
        Return _MyArg
    End Function
End Class
Public Class Grandfather
    Implements IElements
    Public NotOverridable Overrides Function ToString() As String 
        Return GetArg()
    End Function

    Public MustOverride Function GetArg() Implements IElements.GetArg
End Class
