I am trying to create a new object of type Invoice. I pass in the necessary parameters in the correct order.
However, it is telling me that I have included invalid arguments. I might be overlooking something very simple here, but maybe someone can point it out.
I am working on homework, however the Invoice.cs file was included for use with the project.
The only solution I am seeking is why my object will not accept the values. I have never had an issue with objects before.
Here is the code I have:
static void Main(string[] args)
{
Invoice myInvoice = new Invoice(83, "Electric sander", 7, 57.98);
}
And here is the actual Invoice.cs file:
// Exercise 9.3 Solution: Invoice.cs
// Invoice class.
public class Invoice
{
// declare variables for Invoice object
private int quantityValue;
private decimal priceValue;
// auto-implemented property PartNumber
public int PartNumber { get; set; }
// auto-implemented property PartDescription
public string PartDescription { get; set; }
// four-argument constructor
public Invoice( int part, string description,
int count, decimal pricePerItem )
{
PartNumber = part;
PartDescription = description;
Quantity = count;
Price = pricePerItem;
} // end constructor
// property for quantityValue; ensures value is positive
public int Quantity
{
get
{
return quantityValue;
} // end get
set
{
if ( value > 0 ) // determine whether quantity is positive
quantityValue = value; // valid quantity assigned
} // end set
} // end property Quantity
// property for pricePerItemValue; ensures value is positive
public decimal Price
{
get
{
return priceValue;
} // end get
set
{
if ( value >= 0M ) // determine whether price is non-negative
priceValue = value; // valid price assigned
} // end set
} // end property Price
// return string containing the fields in the Invoice in a nice format
public override string ToString()
{
// left justify each field, and give large enough spaces so
// all the columns line up
return string.Format( "{0,-5} {1,-20} {2,-5} {3,6:C}",
PartNumber, PartDescription, Quantity, Price );
} // end method ToString
} // end class Invoice
