如何將 PDF 轉換為 Base64?
PdfDocument 物件並未直接提供取得 Base64 的屬性。不過,您可以取得位元組陣列,進而藉此取得 Base64 字串。
using System;
using SomePdfLibrary; // Make sure to import the library used for handling PDF files
class Program
{
static void Main()
{
// Create a PdfDocument object for the specified PDF file
var pdf = new PdfDocument("MyPDF.pdf");
// Get the binary data (byte array) from the PDF document
var byteArray = pdf.BinaryData;
// Convert the byte array to a Base64 string
var base64Result = Convert.ToBase64String(byteArray);
// Output the Base64 result
Console.WriteLine("Base64 of PDF: " + base64Result);
}
}
using System;
using SomePdfLibrary; // Make sure to import the library used for handling PDF files
class Program
{
static void Main()
{
// Create a PdfDocument object for the specified PDF file
var pdf = new PdfDocument("MyPDF.pdf");
// Get the binary data (byte array) from the PDF document
var byteArray = pdf.BinaryData;
// Convert the byte array to a Base64 string
var base64Result = Convert.ToBase64String(byteArray);
// Output the Base64 result
Console.WriteLine("Base64 of PDF: " + base64Result);
}
}
Imports System
Imports SomePdfLibrary ' Make sure to import the library used for handling PDF files
Friend Class Program
Shared Sub Main()
' Create a PdfDocument object for the specified PDF file
Dim pdf = New PdfDocument("MyPDF.pdf")
' Get the binary data (byte array) from the PDF document
Dim byteArray = pdf.BinaryData
' Convert the byte array to a Base64 string
Dim base64Result = Convert.ToBase64String(byteArray)
' Output the Base64 result
Console.WriteLine("Base64 of PDF: " & base64Result)
End Sub
End Class

說明:
PdfDocument初始化:使用您要轉換的 PDF 檔案名稱來初始化PdfDocument物件。 請將SomePdfLibrary替換為您實際使用的函式庫名稱。BinaryData擷取:它會擷取指定 PDF 的二進位資料(以位元組陣列形式)。- Base64 轉換:使用
Convert.ToBase64String方法將位元組陣列轉換為 Base64 字串。 - 輸出 Base64 字串:將 Base64 編碼的字串輸出至主控台以供驗證。
