	Count	The number of properties contained in the property set.包含属性个数
	GetAllProperties	The name and value of all the properties in the property set.
	GetProperties	The values of the specified properties.
	GetProperty	The value of the specified property.
	IsEqual	True if the property set is the same as the input property set.
	RemoveProperty	Removes a property from the set.
	SetProperties	The values of the specified properties.
	SetProperty	The value of the specified property.

public void GetAllProperties (
    ref object names,
    ref object values                      //The name and value of all the properties in the property set.
);

public void GetProperties (
    object names,
    ref object values                       //The values of the specified properties.
);

public object GetProperty (
    string Name                                //The value of the specified property.
);

主要实例是打开Oracle数据库

//Personal Geodatabase e.g., database = "C:\\myData\\mypGDB.mdb"

<span style="font-size:14px;color:#3333ff;">public IWorkspace open_pGDB_Workspace(string database)</span>

<span style="font-size:14px;color:#3333ff;">{</span>

<span style="font-size:14px;color:#3333ff;"><span style="white-space:pre">	</span>ESRI.ArcGIS.esriSystem.IPropertySet propertySet = new ESRI.ArcGIS.esriSystem.PropertySetClass();</span>

<span style="font-size:14px;color:#3333ff;"><span style="white-space:pre">	</span>propertySet.SetProperty("DATABASE", database);</span>

<span style="font-size:14px;color:#3333ff;"><span style="white-space:pre">	</span>IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesGDB.AccessWorkspaceFactoryClass();</span>

<span style="font-size:14px;color:#3333ff;"><span style="white-space:pre">	</span>return workspaceFactory.Open(propertySet, 0);</span>

<span style="font-size:14px;color:#3333ff;">}</span>

// File Geodatabase e.g., database = "C:\\myData\\myfGDB.gdb"

<span style="color:#3333ff;">public IWorkspace open_fGDB_Workspace(string database)</span>

<span style="color:#3333ff;">{</span>

<span style="color:#3333ff;"><span style="white-space:pre">	</span>ESRI.ArcGIS.esriSystem.IPropertySet propertySet = new ESRI.ArcGIS.esriSystem.PropertySetClass();</span>

<span style="color:#3333ff;"><span style="white-space:pre">	</span>propertySet.SetProperty("DATABASE", database);</span>

<span style="color:#3333ff;"><span style="white-space:pre">	</span>IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesGDB.FileGDBWorkspaceFactoryClass();</span>

<span style="color:#3333ff;"><span style="white-space:pre">	</span>return workspaceFactory.Open(propertySet, 0);</span>

<span style="color:#3333ff;">}</span>

//SDE Geodatabase e.g., server = "Kona"
// database = "sde" or "" if Oracle
// instance = "5151"
// user = "vtest"
// password = "go"
// version = "SDE.DEFAULT"
public IWorkspace open_ArcSDE_Workspace(string server, string instance, string user,string password, string database, string version)
{
	ESRI.ArcGIS.esriSystem.IPropertySet propertySet = new ESRI.ArcGIS.esriSystem.PropertySetClass();
	propertySet.SetProperty("SERVER", server);
	propertySet.SetProperty("INSTANCE", instance);
	propertySet.SetProperty("DATABASE", database);
	propertySet.SetProperty("USER", user);
	propertySet.SetProperty("PASSWORD", password);
	propertySet.SetProperty("VERSION", version);
	IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesGDB.SdeWorkspaceFactoryClass();
	return workspaceFactory.Open(propertySet, 0);
