IWorkspaceName接口

概述：

给成员提供存取，提供工作空间名称信息。注：该接口已经取代iworkspacename2 iworkspacename。请考虑使用较新的版本。

	AllProperties Methods	Description
	BrowseName	The browse name of the WorkspaceName.
	Category	The category of the WorkspaceName.
	ConnectionProperties	The connection properties of the WorkspaceName.
	PathName	The path name of the WorkspaceName.
	Type	The type of the associated workspace.
	WorkspaceFactory	The workspace factory of the WorkspaceName.
	WorkspaceFactoryProgID	The ProgID of the WorkspaceName's workspace factory.

IWorkspaceName接口能够获得工作空间的相关Name属性，为了创建一个IWorkspaceName，首先要设置WorkspaceFactoryProgID属性或者PathName、ConnectionProperties属性。IWorkspaceName接口能指向一个已经存在的工作空间，或者一个已经被创建的工作空间，如果IWorkspaceName已经存在，可以通过IName::Open方法打开创建，此方法相当于利用IWorkspaceFactory的Open和OpenFromFile方法打开。如果此接口实例不存在，可以用IWorkspaceFatory::Create方法创建。
在某些情况下，你可能已经有了一个完整的工作区对象但需要一个工作空间的名字。你可以检索工作区名称从工作区通过调用调用IDataset::FullName获取工作区上的全名。

    //e.g., workspacePath = "D:\data\geodatabases\Usa.mdb"
    public void IWorkspace__get_WorkspaceName(string workspacePath, IWorkspace workspace)
    {
        //Creates a new workspace name for a personal geodatabase.
        IWorkspaceName workspaceName = new WorkspaceNameClass();
        workspaceName.WorkspaceFactoryProgID = "esriDataSourcesGDB.AccessWorkspaceFactory";
        workspaceName.PathName = workspacePath;
        //Or Get a workspace name from an existing workspace.
        IDataset dataset = (IDataset)workspace; //Workspaces implement IDataset
        workspaceName = (IWorkspaceName)dataset.FullName;
    }
