Hi,
Any objects inherit System.ValueType, like int(Int32) and
datetime
are impossible to set null.
This is the C# specification.
As long as you use wsdl.exe, you can't set null value to
them.
So they must be checked on the client side
according to your design.
Then TypedDataSet is usefull
because you need something to tell your design specification
like default value
to your client program developer.
TypedDataSet is a subclass of DataSet.
ColumnName, ColumnType, Relations are defined at design
time.
And they are written as a XSD file.
(XSD file can be used to generate
automatically TypedDataSet class)
But this may not be your wanted solution.
Takenori,

Subject: RE: Antwort: RE: Dot-Net's "wsdl.exe" and Non-Nullable Value Types[snip]I suggest you provide a TypeDataSet object for your .NET clients.[end snip]Forgive my ignorance ... but is this a real class in .NET? If so, do you know the namespace? I didn't find it when I searched.Or, is this just another way of indicating that I build a Wrapper for .NET's "int"? Thanks for your assistance.Erik
