'nonNegativeInteger' is an invalid value for the XmlElementAttribute.DataType property. nonNegativeInteger cannot be converted to System.Int32.

I am getting the following error when I try and load my Web Service

'nonNegativeInteger' is an invalid value for the XmlElementAttribute.DataType property. nonNegativeInteger cannot be converted to System.Int32.

[XmlElement(DataType="nonNegativeInteger", Order=0, ElementName="AmountInEuroCent")]
public int AmountInEuroCent
{
get { return amountInEuroCent; }
set
{
if ((amountInEuroCent != value))
{
amountInEuroCent = value;
RaisePropertyChanged("AmountInEuroCent");
}
}
}

The above Property appears to be the issue. I guess I could change it to a string but then that really wouldn't be ideal. As I would then have to do loads of conversions from string to int.

Any ideas?

What is nonNegativeInteger? Is this a class you wrote?

Can you try making your property uint instead of int? This is the correspondence of non negative integer.

Cheers, I bounded them to String as a temp solution back when I posted the question. I believe it's got me around the problem but I really wanted to avoid doing Convert.ToInt

But I guess it can't be avoided.

I don't think the overhead will be great. Even if you have it directly mapped, .Net will do the convertion and it won't be faster.
