本文提供了使用ArcGIS SDK在不同数据源下（如Access数据库、FileGDB、ArcSDE和Shapefile）打开工作空间的示例代码。通过具体的路径示例，展示了如何利用IWorkspaceFactory接口打开各种地理数据库。

//IWorkspaceFactory OpenFromFile Example

    //e.g., nameOfFile = "E:\\data\\english\\access\\canada\\canada.mdb"
    public IWorkspace IWorkspaceFactory_OpenFromFile_Example_Access(string nameOfFile)
    {
        IWorkspaceFactory workspaceFactory= new ESRI.ArcGIS.DataSourcesGDB.AccessWorkspaceFactoryClass();
        return workspaceFactory.OpenFromFile(nameOfFile, 0);
    }

    //e.g., nameOfFile = "E:\\data\\english\\FileGDB\\canada\\canada.gdb"
    public IWorkspace IWorkspaceFactory_OpenFromFile_Example_FileGDB(string nameOfFile)
    {
        IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesGDB.FileGDBWorkspaceFactoryClass();
        return workspaceFactory.OpenFromFile(nameOfFile, 0);
    }

    //e.g., nameOfFile = "D:\\data\\redarrow.sde"
    public IWorkspace IWorkspaceFactory_OpenFromFile_Example_ArcSDE(string nameOfFile)
    {
        IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesGDB.SdeWorkspaceFactoryClass();
        return workspaceFactory.OpenFromFile(nameOfFile, 0);
    }

    //The connection string for a shapefile should be the full path
    //to the Shapefile's folder (e.g., "C:\\temp")
    // Note: location cannot be relative path ".\\temp" it must be an explicit pathname
    public IWorkspace IWorkspaceFactory_OpenFromFile_Example_Shapefile(string nameOfFile)
    {
        IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesFile.ShapefileWorkspaceFactoryClass();
        return workspaceFactory.OpenFromFile(nameOfFile, 0);
    }
