1、打开GDB
FileGDBWorkspaceFactory fileGDBWorkspaceFactory = new FileGDBWorkspaceFactory();
IWorkspace workspace = fileGDBWorkspaceFactory.OpenFromFile("GDB路径", 0);
IFeatureWorkspace featureWorkspace = workspace as IFeatureWorkspace;
IFeatureClass featureClass = featureWorkspace.OpenFeatureClass("GDB中要素类名字");

2、打开mdb
AccessWorkspaceFactory accessWorkspaceFactory = new AccessWorkspaceFactoryClass();
IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)accessWorkspaceFactory.OpenFromFile("MDB路径", 0);
IFeatureClass featureClass = featureWorkspace.OpenFeatureClass("MDB中要素类名字");

3、打开shapefile
IWorkspaceFactory workspaceFactory = new ShapefileWorkspaceFactoryClass();
IWorkspace workspace = workspaceFactory.OpenFromFile("shp路径", 0);
IFeatureWorkspace featureWorkspace = workspace as IFeatureWorkspace;
IFeatureClass featureClass = featureWorkspace.OpenFeatureClass("shp名字");

注：对workspace验证是否存在
if (fileGDBWorkspaceFactory.IsWorkspace(GDBPath) == false)
{
msg = "GDB文件不正确，不能打开！";
return msg;
}
