Šioje trumpoje mokymo programoje paaiškinama, kaip sujungti PDF su C# REST API. Išmoksite sujungti visus PDF failus su C# REST sąsaja naudodami SDK. Jame bus paaiškinti visi veiksmai, kurių reikia norint sukurti programą, skirtą kelių PDF failų derinimui.
Būtina sąlyga
parsisiųsti Aspose.PDF Cloud SDK for Dotnet
Nustatykite C# projektą naudodami aukščiau pateiktą SDK
Veiksmai, kaip sujungti PDF su C# Low Code API
- Nustatykite API raktą ir SID PdfApi klasės objekto inicijavimui
- Sukurkite objektą MergeDocuments ir pateikite PDF failų, kuriuos norite sujungti, sąrašą
- Įkelkite visus šaltinio PDF failus naudodami UploadFile() metodą PdfApi klasėje
- Iškvieskite metodą PutMergeDocuments(), kad sujungtumėte visus PDF failus į vieną paskirties PDF failą
- Atsisiųskite ir išsaugokite išvesties PDF failą, kuriame yra visų sujungtų PDF failų turinys
Šie veiksmai apibendrina, kaip sujungti PDF internete su C# REST API. Naudokite MergeDocuments klasės objektą, kad sukurtumėte PDF failų, kuriuos norite sujungti, sąrašą ir įkelkite visus šiuos PDF failus į debesį naudodami PdfApi.UploadFile() metodą ir iškvieskite PutMergeDocuments() metodą, kad sujungtumėte PDF failus internete. API iškvietimas grąžina būseną Gerai, po to galite iškviesti metodą DownloadFile, kad gautumėte išvesties PDF failą.

Šis kodas mus išmokė, kaip sujungti PDF failus su C# REST sąsaja. Metodo UploadFile() naudokite panašius pavadinimus, kurie naudojami PDF failų sąraše objekte MergeDocuments. Atsisiuntę gautą PDF failą, nustatykite parametrą Position į nulį, kitaip negalėsite išsaugoti failo diske.
Šiame straipsnyje paaiškinta, kaip sujungti PDF dokumentus internete naudojant C# .NET pagrįstą API. Norėdami sukurti tuščią PDF failą, žr. šį straipsnį: Sukurkite PDF dokumentą naudodami NET REST API.
