Tutorial singkat ini memandu cara menggabungkan PDF dengan C# REST API. Anda akan belajar menggabungkan semua PDF dengan C# REST Interface menggunakan SDK. Ini akan menjelaskan semua langkah yang diperlukan untuk mengembangkan aplikasi untuk menggabungkan beberapa file PDF.
Prasyarat
Siapkan proyek C# dengan SDK di atas
Langkah-langkah Menggabungkan PDF dengan C# Low Code API
- Tetapkan kunci API dan SID untuk menginisialisasi objek kelas PdfApi
- Buat objek MergeDocuments dan berikan daftar file PDF yang ingin Anda gabungkan
- Unggah semua file PDF sumber menggunakan metode UploadFile() di kelas PdfApi
- Panggil metode PutMergeDocuments() untuk menggabungkan semua file PDF menjadi satu file PDF tujuan
- Unduh dan simpan file PDF keluaran yang berisi konten semua file PDF yang digabungkan
Langkah-langkah ini merangkum cara menggabungkan PDF online dengan C# REST API. Gunakan objek kelas MergeDocuments untuk membuat daftar file PDF yang ingin Anda gabungkan, dan unggah semua file PDF ini ke cloud menggunakan metode PdfApi.UploadFile(), dan aktifkan metode PutMergeDocuments() untuk menggabungkan file PDF secara online. Panggilan API mengembalikan status OK setelah itu Anda dapat memanggil metode DownloadFile untuk mengambil file PDF keluaran.

Kode ini telah mengajari kita cara menggabungkan file PDF dengan Antarmuka C# REST. Gunakan nama serupa dalam metode UploadFile() seperti yang digunakan dalam daftar file PDF di objek MergeDocuments. Saat Anda mengunduh file PDF yang dihasilkan, atur parameter Posisi ke nol jika tidak, Anda tidak akan dapat menyimpan file di disk.
