由图层判断数据源类型

原文由图层判断数据源类型

通过IWorkspaceName接口的WorkspaceFactoryProgID属性来判断 图层数据源类型。

IFeatureClass pFC = pFeatureLyr.FeatureClass;
IDataset dataset = pFC as IDataset;
IWorkspaceName ws = ((IDatasetName)(dataset.FullName)).WorkspaceName;
if (ws.WorkspaceFactoryProgID.IndexOf("AccessWorkspaceFactory") > -1)
{

}
else if (ws.WorkspaceFactoryProgID.IndexOf("FileGDBWorkspaceFactory") > -1)
{

}
else if (ws.WorkspaceFactoryProgID.IndexOf("SdeWorkspaceFactory") > -1)
{

}
