comparing start date with in the same list using C#

I have class called LaborRate as below. It has Id, start date, end date column.
user can see existing records from database table in a grid and he can edit them and/or he can add new records to the grid.
while saving existing modified records or new records I need to do below validation.
If the Start Date or End Date falls within Start Date & End Date on other record for then I need to through some error. I cannot depend on Id column because for newly added record the id value is -1. What is the best method to do this comparison.
public class LaborRate
{
private int _id;
private decimal _laborRate;
private DateTime _StartDate;
private DateTime _EndDate;
public int Id
{ get { return _id; } set { _id = value; } }
public Decimal Rate
{ get { return _laborRate; } set { _laborRate = value; } }
public DateTime StartDate
{ get { return _StartDate; } set { _StartDate = value; } }
public DateTime EndDate
{ get { return _EndDate; } set { _EndDate = value; } }
}

how do i check if DateTime is null

if (string.IsNullOrEmpty(value)) is for string, but what is the code to check if Datetime is null?
private DateTime? _ReleaseDate;
public DateTime? ReleaseDate
{
get
{
return _ReleaseDate;
}
set
{
if ()
{
}
else
{
_ReleaseDate = value;
}
}
}

The ValueType? pattern is shorthand for Nullable<ValueType>. In your case you have Nullable<DateTime>.
As you can see from the docs, Nullable<ValueType> implements a HasValue property, so you can simply check it like so:
if (value.HasValue)
{
}
else
{
}
If you simply want to set a default value you can use the GetValueOrDefault method of Nullable<T> and do away with the if statement:
_ReleaseDate = value.GetValueOrDefault(DateTime.MinValue); // or whatever default value you want.

For nullbale types you can use HasValue or != null
However for your example (with the code shown), you have more options
public DateTime? ReleaseDate
{
get
{
return _ReleaseDate;
}
set
{
// if value is null, then that's all good, _ReleaseDate will be null as well
_ReleaseDate = value;
}
}
Or
public DateTime? ReleaseDate {get;set}
The only reason you would need to do something like below, is when you have some specific behaviour on null or otherwise
public DateTime? ReleaseDate
{
get
{
return _ReleaseDate;
}
set
{
if (value.HasValue)
{
// has a value
}
else
{
// doesnt
}
}
}

InnerException:When converting a string to DateTime. parse the string to date the date before putting each variable into the DateTime object

I am trying to deserialize XML returned from an API call but am getting "InnerException:When converting a string to DateTime. parse the string to date the date before putting each variable into the DateTime object"
The XML looks like this
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<agentInventory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:N1="demo.org.uk/demo/CustomsStatus" xmlns:N2="demo.org.uk/demo/UnLocation" xmlns:N3="demo.org.uk/demo/AirCarrier" xmlns="demo.org.uk/demo/AgentInventory">

</agentInventory>
The code used to deserialize the XML is
if (storeXmlInventoryReturnData != null)
{
//DeSerialize XML from storeXmlInventoryReturnData variable
agentInventory myInventoryResponse = null;
XmlSerializer xmlSerializer = new XmlSerializer(typeof(agentInventory));
myInventoryResponse = (
agentInventory)xmlSerializer.Deserialize(new StringReader(storeXmlInventoryReturnData)
);
Console.WriteLine(

myInventoryResponse.sdc,
myInventoryResponse.grossWeight,
myInventoryResponse.goodsDescription
);
Console.ReadLine();
}
else
{
Console.Write("No data returned");
}
}
The exception is thrown at;
myInventoryResponse = (
agentInventory)xmlSerializer.Deserialize(new StringReader(storeXmlInventoryReturnData));
I guess I need to convert the myInventoryResponse.flightDate to a DateTime object but I am at a loss how to achieve this?

For my own sanity sake, I tried getting the provided XML to work with your classes and the nullable DateTime fields.
For them to work, replace the below properties with those linked below.
The default value for a DateTime object is DateTime.MinDate, so if the incoming value is null or empty, then the property will have a value of DateTime.MinDate anyway, for this you might need to additional validation/changes if your code needs to cater for this.
#region XML Nullable helper properties

Validation inside a class property

The code is as follows:
public class MyEvent
{
public string EventTitle { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public bool IsInsideSameMonth
{
get
{
// No code is bug-free, so we assume this situation may occur somehow.
if (StartDate > EndDate)
{
// And when this occurs, we want to halt the application by throwing exception to prevent further potential damage.
throw new MyEventException("Start date is not supposed to be greater than end date.");
}
return (StartDate.Year == EndDate.Year && StartDate.Month == EndDate.Month);
}
}
public void Validate()
{
if (StartDate > EndDate)
{
throw new MyEventException("Start date is not supposed to be greater than end date.");
}
if (String.IsNullOrWhiteSpace(EventTitle))
{
throw new MyEventException("Title cannot be empty.");
}
}
}
public class MyEventException : Exception
{
public MyEventException(string message)
: base(message)
{
}
}
It might seem redundant that I perform StartDate > EndDate validation inside the IsInsideSameMonth property. I just prefer being on the safe side. But it feels as if I am doing something wrong but I cannot describe it.
Is this a good practice? Please share your valuable experience and thoughts.

You shouldn't use Auto-implemented property. You should instead use a backing private field and then check while setting the property like:
private DateTime _StartDate;
public DateTime StartDate
{
get { return _StartDate; }
set
{
if (value > _EndDate)
{
throw new MyEventException("Start date is not supposed to be greater than end date.");
}
else
{
_StartDate = value;
}
}
}
private DateTime _EndDate;
public DateTime EndDate
{
get { return _EndDate; }
set { _EndDate = value; }
}
Your current code would allow the user to set StartDate to any value and you will only realize if you check your property IsInsideSameMonth.

For the EventTitle you could declare a backing field and make the validation inside the setter of the property. Something like this:
string eventTitle;
public string EventTitle
{
get
{
return eventTitle;
}
set
{
if(!IsNullOrWhiteSpace(value))
eventTitle = value;
else
throw new MyEventException("Title cannot be empty.");
}
}
As for the DateTime objects you could follow the same path:
private DateTime startDate;
public DateTime StartDate
{
get
{
return startDate;
}
set
{
if (value > EndDate)
{
throw new MyEventException("Start date is not supposed to be greater than end date.");
}
else
{
startDate = value;
}
}
}
private DateTime endDate;
public DateTime EndDate
{
get
{
return endDate;
}
set
{
endDate = value;
}
}

It's better to control values when the properties are set, so you need to convert your automatic properties to old style (properties with private field) and put your checking there.

Here is the Microsoft property design guide.
Here is an example checking the values when setting, throwing if invalid. I've also defined functions for validation to reduce redundant code (in case you want to change your validation or error messaging- it will be in one location).
public class MyEvent
{
public bool IsInsideSameMonth
{
get
{
return (StartDate.Year == EndDate.Year && StartDate.Month == EndDate.Month);
}
}
private string _EventTile;
public string EventTitle
{
get { return _EventTile; }
set
{
ValidateTitle(value); // this will throw if invalid and leave the value of _EventTitle unchanged
_EventTile = value;
}
}
private DateTime _StartDate = DateTime.MinValue;;
public DateTime StartDate
{
get { return _StartDate; }
set
{
ValidateDates(value, EndDate); // this will throw if invalid and leave the value of _StartDate unchanged
_StartDate = value;
}
}
private DateTime _EndDate = DateTime.MaxValue;;
public DateTime EndDate
{
get { return _EndDate; }
set
{
ValidateDates(StartDate, value); // this will throw if invalid and leave the value of _EndDate unchanged
_EndDate = value;
}
}
private void ValidateDates(DateTime start, DateTime end)
{
if (start > end)
{
throw new MyEventException("Start date is not supposed to be greater than end date.");
}
}
private void ValidateTitle(string title)
{
if (String.IsNullOrWhiteSpace(title))
{
throw new MyEventException("Title cannot be empty.");
}
}
public void Validate()
{
ValidateDates(StartDate, EndDate);
ValidateTitle(EventTitle);
}
}
public class MyEventException : Exception
{
public MyEventException(string message)
: base(message)
{
}
}

Web service not returning integer data in an object [duplicate]

This question already has answers here:
Closed 11 years ago.

VS2003 Web Reference for a WCF Service has Extra "IdSpecified" Parameter
Thanks everyone. I totally missed that. Yes, the class name is awful.
I have a web service (ASMX) that returns an object which contains an array.
I first define my response object:
APIResponse response = new APIResponse();
Fill a datatable:
dtHolder = SqlHelper.ExecuteDatatable(connstring, CommandType.StoredProcedure, strSelect, aParams);
Create a holder for the results of my query:
API036RsBkgDetRec[] BkgDetRec_Array = new API036RsBkgDetRec[dtHolder.Rows.Count];
int i = 0;
foreach (DataRow row in dtHolder.Rows)
{
BkgDetRec_Array[i] = new API036RsBkgDetRec();
BkgDetRec_Array[i].eqoEqszId = row[0].ToString();
BkgDetRec_Array[i].eqoEqtpId = row[1].ToString();
BkgDetRec_Array[i].eqoEqhtId = row[2].ToString();
BkgDetRec_Array[i].qty = Convert.ToInt32(row[3]);
BkgDetRec_Array[i].receiveQty = Convert.ToInt32(row[4]);
BkgDetRec_Array[i].emptyTally = Convert.ToInt32(row[5]);
BkgDetRec_Array[i].maxEmpty = Convert.ToInt32(row[6]);
BkgDetRec_Array[i].chsQty = Convert.ToInt32(row[7]);
BkgDetRec_Array[i].chsTally = Convert.ToInt32(row[8]);
i++;
}
and populate the array I am returning (bkgDetTable) with the holder array I just populated above:
response.bkgDetTable = BkgDetRec_Array;
When I capture the output, I see that none of the integer fields are being created even though when I step through the code, they are being populated with real numbers. The object API036RsBkgDetRec also has them defined as integer values. Only the ones defined as string are coming across.
<bkgDetTable xmlns="http://sdfsd/xsd">
<eqoEqhtId>96</eqoEqhtId>
<eqoEqszId>40</eqoEqszId>
<eqoEqtpId>DR</eqoEqtpId>
</bkgDetTable>

Any ideas?

For all the INT fields, you have two fields:
the actual int field which I'm sure you're already setting to the proper value (private int emptyTallyField;)
but you also have a field called private bool emptyTallyFieldSpecified; which must be set to true - otherwise that int value you set will not be serialized out
The reason for this is because for a reference-type field like a string field, you can have NULL to represent the "there is no value" aspect, and you can have an empty string or any other string in there.
For value types, like int - how else would you represent the "there is no value specified" case? If you set the int field to 0 - is that 0 because you want that "zero" as the value, or is that "0" because you really want to say "there is no value". For this reason, all value types have this additional (fieldname)specified property which indicates whether or not an actual value is present. If that specified-flag is not set (and it's not set by default), then you have no value - thus nothing gets serialized out.

You will notice that for each property value type (integer, double, DateTime, ...) you have a XXXSpecified boolean property. For example you have:
public int maxEmpty
and
public bool maxEmptySpecified
Those properties are generated when you import a WCF web service using wsdl.exe (or Add Web Reference in Visual Studio). You need to set them to true every-time you set their corresponding value type property value.
I agree that this is total crap but, that's how it is. ASMX is deprecated now.
