.NET 2 System.Nullable always returns null
We are using Axis 1.1 with a C# .NET 2 client. A snippet of the WSDL and
a snippet of the generated C# proxy class is given at the end of this
mail.
In the WSDL the element 'type' is declared as nillable="true", which in
the C# proxy class is translated to the following:
[System.Xml.Serialization.SoapElementAttribute(IsNullable=true)]
public System.Nullable<IASReportType> type {
get {
return this.typeField;
}
set {
this.typeField = value;
}
}
When we call our C# .NET 2 client, we expect the value 'ON_DEMAND' to be
returned for the typeField but null is returned.
Removing the System.Nullable syntax so that the method signature reads
public IASReportType type solves the problem i.e. 'ON_DEMAND' is
returned as the value
Does anyone have any explanation and/or a solution for this problem?
Thank you.
