C# code examples
for Value Objects
This page contains C# code examples for ArcGIS Server SOAP value objects
used for input and output types. The samples apply
to both desktop and Web applications. Note that
the same value object type may be utilized by multiple proxy types (multiple
service types). SOAP proxy classes and methods
may be included to demonstrate the use of a value object. By
default, the name for the SOAP proxy class is the name of the service
used to generate it plus the service type. For
example, if a SOAP proxy class is generated dynamically using a map service
named "NorthAmerica", the proxy class name will be "NorthAmerica_MapServer". For
the purposes of the example code, the proxy class names will be <service
name>_<service type>.
