[DOTNET] Dataset problem

[Richard Grimes]

I have tried every combination I can think of, but I cannot get this to
work. Has anyone got any suggestions?

When I run this code I get the three <add> statements under the
<configuration> element and not under the <appSettings> element.

void ChangeValue(DataSet* data, String* name, String* value)
{
   DataTable* dt = data->Tables->Item[S"appSettings"];
   if (dt != 0)
   {
      DataRelation* add = dt->ChildRelations->Item[S"appSettings_add"];
      if (add != 0)
      {
         DataTable* addTable = add->ChildTable;
         DataRow* dr = addTable->NewRow();
         dr->Item[S"key"] = name;
         dr->Item[S"value"] = value;
         addTable->Rows->Add(dr);
      }
   }
}

void main()
{
   DataSet* data = new DataSet;
   data->ReadXml(
         AppDomain::CurrentDomain->SetupInformation->ConfigurationFile);

   ChangeValue(data, S"One", S"1");
   ChangeValue(data, S"Two", S"2");
   ChangeValue(data, S"Three", S"3");

   data->AcceptChanges();
   data->WriteXml(
         AppDomain::CurrentDomain->SetupInformation->ConfigurationFile);
}
