打开DBF表->创建图层ESRI arcobjects

Question

我已经成功打开了一个 DBF 表：

String dbfDirectoryPath = "Z:/ESRI/data/washingtonCountyDataFiles/tlg_roads";
IWorkspaceFactory workspaceFactory = new ShapefileWorkspaceFactory();
IWorkspace workspace = workspaceFactory.OpenFromFile(dbfDirectoryPath, 0);
IFeatureWorkspace featureWorkspace = workspace as IFeatureWorkspace;
String dbfTable = "tlg_roads_l.dbf"; 
ITable table = featureWorkspace.OpenTable(dbfTable);

现在我想映射它，我认为这需要调用 mapControl.AddLayer(layer)。所以我需要以某种方式将此对象从 featureWorkspace 转换为 ILayer。

看起来我可以只 CreateFeatureClass 然后转换为 ILayer，但是 CreateFeatureClass 有 6 个参数，包括 CLSID，所以我觉得我遗漏了一些概念点。感谢您的任何建议:)

//IFeatureClass featureclass = tableWorkspace.CreateFeatureClass //req six args, incl. CLSID
ILayer layer = featureclass as ILayer;
mapControl.AddLayer(layer);

显然，DBF 文件不用于查看，只有形状文件用于渲染，并且显然 DBF 以某种方式包含形状文件所需的数据。这是我被告知的，无论如何请随时启发我。
