The Ocean Module
// create a ModuleTrust from the namespace, type, assembly string
ModuleTrust mt = new ModuleTrust(moduleTrustName);
// add the ModuleTrust to the known trust
CoreSystem.Modules.AddModuleTrust(mt);
// add the modules in the collection to the known modules
CoreSystem.AddModules(col, moduleTrustName);
}
}
Private void CoreSystemStateChanged(object sender,
SystemStateEventArgs e)
{
// Make sure we’re beyond IntegratePresentation.
if (e.State.Equals(SystemState.Running))
{
// we assume we’ve added a moduletrust for our purposes
// earlier, perhaps in the configuration file
string demoTrustName = "DemoModuleTrust";
// create a collection to hold the module
ModuleReferenceCollection col = new ModuleReferenceCollection();
// add our module to the collection using the assembly
// qualified typename
string moduleName = "Demo.MyModule, MyModuleAssembly";
col.AddModule(moduleName);
// add the modules in the collection to the known modules,
// and place them in the moduletrust named “DemoModuleTrust”
CoreSystem.AddModules(col, demoTrustName);
}
}
Module Trust
The ModuleManager class also manages module trusts. A module trust represents
the trust level held by a group of assemblies. When assemblies are loaded into the
Ocean Core through a system factory implementation, or through the
CoreSystem.AddModules method, they will be associated with a
ModuleTrust object.
A ModuleTrust can be strong by associating with a public key or weak by not
associating with a key. A strong ModuleTrust will cause assembly loading to fail
for assemblies that are not signed with the key specified by the ModuleTrust.
You find all module trusts through the ModuleTrust property, or you can a specific
module trust using its name as a string and the GetModuleTrust method.
Additionally you can find the module trust that contains a specific module and all the
modules loaded to a specific module trust.
