น่าเสียดายที่ไม่มีวิธีการส่งคำขอโดยชั้นเรียนแบบไดนามิก คุณต้องตั้งโปรแกรมผ่านไฟล์ fdl ในการเพิ่มบริการ (เช่น WFS) คุณสามารถใช้รหัสด้านล่าง
IWorkspaceFactory factory = (IWorkspaceFactory)new FMEWorkspaceFactoryClass();
IFeatureWorkspace workspace = (IFeatureWorkspace)factory.OpenFromFile("d:\test", 0);
IFeatureDataset fds = workspace.OpenFeatureDataset("name.fdl");
ไชโย!
PS: คุณลองใช้อินเทอร์เฟซIWFSServerหรือไม่ ผมใช้ฟังก์ชั่น DI หนึ่งในโครงการก่อนหน้านี้ของฉันไปที่ข้อมูลการส่งออกไปยังรูปแบบ GML ใช้QuickExport คุณสามารถลองใช้QuickImportและเลือก WFS เป็นแหล่งที่มา ฉันกำลังดูรหัส QuickExport สำหรับการอ้างอิงของคุณ ...
