I have written a web service in C#, .NET 1.1 which reads a XML file into a
dataset.
This is just a plain XML file. First I use the Dataset.ReadXmlScheme
function and pass the XML file to it. Then I convert data type of one of the
column to integer and then I use the Dataset.ReadXml function and pass the
same file to it. This works on my machine, but when I run it on a .NET 2.0
machine it thows an exception with message "Input string was not in correct
format". The XML document is well formed and also all the column has all
values numeric.
So I installed .NET 2.0 on my machine keeping .NET 1.1 as it was. Then on
asociating the web service virtual directory in IIS with .NET 1.1 it works
fine and on associating it with .NET 2.0 it gives above error.
Does it has to do with converting the column to integer type? 8 5668
Can you give me the XML which causes this, as well as the call stack where
the Exception is thrown?
Thanks,
Zafar

The attachement was blocked since it was an XML file, please send in some
other format like .zip.

news:uo**************@TK2MSFTNGP10.phx.gbl... The attached file (only part of it as the original file is large) contains an attribute score for in every child element. This after loading the schema into the dataset is converted to integer format using ReadXmlSchema function of the DataSet class and then the XML file is read using the ReadXml function. Suprisingly it works fine if I associate it to run with .NET 1.1 and does not if I associate it with .NET 2.0 with out. Also I am not able to debug when I use .NET 2.0 using Visual Studio 2003. This is the call stack [FormatException: Input string was not in a correct format.] System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)

Thanks. Could you also post the code which works in .NET 1.1 and not in .NET

This is the part of code wich works in .Net Framework 1.1 and not in 2.0.
The try block throws exception at the statement dataSet.ReadXml(xmlFile)
Nikhilesh ,
I am realy sorry, I need you to send me the XML file again. I am unable to
locate it in the archive.

Nikhilesh,
This is an issue in .NET framework 2.0 which might be fixed in a service
pack. As a work around for .NET 2.0, could you rename your attribute score,
so that its name is different than the element itself.
Thanks,
Zafar

Well, may be that also. But also the name of the root element and the name
of the child element is same that was causing problem. I changes the name of
the root element from <score> to <scores> and it worked. May be .Net 2.0 is
strict about the names of root element and child elements
