SDE for sqlserver直連的ArcEngine訪問

Ae中的數據的連接實質還是采用服務連接的方式。連接代碼如下：

 1  public IWorkspace Getworkspace()
 2   {
 3       IPropertySet propertySet = new PropertySetClass();
 4       propertySet.SetProperty("SERVER", "127.0.0.1");  
 5       propertySet.SetProperty("INSTANCE", "sde:sqlserver:127.0.0.1
 
");
 6       propertySet.SetProperty("DATABASE", "sde");
 7       propertySet.SetProperty("USER", "sa");
 8       propertySet.SetProperty("PASSWORD", "sa");
 9       propertySet.SetProperty("VERSION", "SDE.DEFAULT"); 
10 　　 　Type factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.SdeWorkspaceFactory
 
");
11       IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);
12       return workspaceFactory.Open(propertySet, 0);
13  }
