如何读SDE中图层名？

<P>我已经完成SDE的连接，将Shape数据通过SDE导入Microsoft SQL Server 2000中。</P>
<P>现在先完成SDE的连接，再将导入的图层读入ListBox 中，就不知道如何实现了？</P>
<P>以下是连接SDE代码：</P>
<P>                      Dim pWorkspaceFactory As IWorkspaceFactory<BR>                  　Dim pWorkspace As IFeatureWorkspace<BR>                  　Dim pPropSet As IPropertySet<BR>                  　Dim pClass As IFeatureClass<BR>                  　Dim pLayer As IFeatureLayer<BR>                  　Dim pMxDoc As IMxDocument<BR>                  　Set pWorkspaceFactory = New SdeWorkspaceFactory<BR>                  　Set pPropSet = New PropertySet<BR>                  　With pPropSet '设置ArcSDE连接属性<BR>                  　　.SetProperty "SERVER", Server<BR>                  　　.SetProperty "INSTANCE", Instance<BR>                  　　.SetProperty "USER", User<BR>                  　　.SetProperty "PASSWORD", Password<BR>                  　　.SetProperty "VERSION", version '可选，缺省为SDE.DEFAULT版本<BR>                  　End With<BR>                  　Set pWorkspace = pWorkspaceFactory.Open(pPropSet, 0)</P>
<P>                  '如何将图层加载到List1？</P>
