操作指南
從內存中讀取PDF文件
MemoryStream to PDF C#
View the article in
English
我們可以在 C# .NET 中將 MemoryStream 加載並創建為 PDF 文件，而不需要觸及文件系統。 這可以通過 System.IO .NET 命名空間中的 MemoryStream 對象實現。
快速入門: 在 C# 中從 MemoryStream 創建 PDF
只需一行代碼，使用 IronPDF 即可輕鬆將 MemoryStream 轉換為 PDF。 此快速入門指南展示瞭如何輕鬆地從 MemoryStream 初始化 PdfDocument，使開發人員能夠無縫地將 PDF 創建集成到他們的 C# 應用程序中，而無需處理物理文件。 非常適合涉及內存中數據處理、網絡通信或實時數據轉換的場景。
Install IronPDF with NuGet Package Manager
Copy and run this code snippet.
var bytes = File.ReadAllBytes("sample.pdf");
var pdfDoc = new IronPdf.PdfDocument(myMemoryStream);

從內存加載 PDF
新的 IronPdf.PdfDocument 實例可以從以下任何 .NET 內存對象中初始化：
MemoryStream
FileStream
作為字節數組的二進制數據 (byte[])
以下是直接從 PDF 文件中讀取流並使用 C# 創建 PdfDocument 對象的示例：
:path=/static-assets/pdf/content-code-examples/how-to/pdf-memory-stream-from-stream.cs
using IronPdf;
using System.IO;
// Read PDF file as stream
var fileByte = File.ReadAllBytes("sample.pdf");
// Instantiate PDF object from stream
PdfDocument pdf = new PdfDocument(fileByte);Imports IronPdf
Imports System.IO
' Read PDF file as stream
Private fileByte = File.ReadAllBytes("sample.pdf")
' Instantiate PDF object from stream
Private pdf As New PdfDocument(fileByte)
$vbLabelText
$csharpLabel
提供的示例演示了如何直接從文件系統讀取 PDF 文件並創建 PdfDocument 對象。 但是，您也可以從通過網絡通信或任何其他數據交換協議接收到的字節數組初始化 PdfDocument。 這使您可以將 PDF 數據轉換為可編輯的對象，使您能夠根據需要進行修改。

常見問題解答
若要在 C# 中將 MemoryStream 轉換為 PDF，請從 NuGet 下載 IronPDF 庫。取得 PDF 檔案的位元組數據，並使用PdfDocument建構函數將此位元組陣列載入到 PDF 物件中。然後，您可以根據需要修改 PDF，最後匯出更新的文件。
是的，您可以使用 IronPDF 從各種 .NET 記憶體物件（例如 MemoryStream、FileStream）和以位元組數組表示的二進位資料初始化PdfDocument 。
首先，下載 IronPDF 庫。然後，取得 PDF 檔案的位元組數據，並使用PdfDocument建構函數將位元組數組載入到 PDF 物件中。在匯出 PDF 之前，進行任何必要的修改。
使用 IronPDF 將 PDF 從 MemoryStream 載入到PdfDocument物件後，可以在儲存更新後的文件之前新增頁首、頁尾和其他內容。
在 PDF 處理中使用 MemoryStream 可以讓您在記憶體中處理 PDF 操作，而無需與檔案系統交互，這對於需要動態生成或修改 PDF 的應用程式來說是理想的選擇。
對PdfDocument進行更改後，可以使用 IronPDF 提供的SaveAs方法將修改後的 PDF 儲存回 MemoryStream。
是的，IronPDF 可讓您從位元組數組初始化PdfDocument ，從而方便處理透過網路通訊或其他資料交換協定接收的 PDF 資料。
常見問題包括正確處理位元組數組以及確保將 PDF 資料正確載入到PdfDocument物件中。 IronPDF 提供了強大的方法來有效率地管理這些流程。
是的，IronPDF 與 .NET 10 完全相容。它支援 .NET 10（以及 .NET 9、8、7、6 和 Framework/Core 版本）的項目，因此您可以在 .NET 10 中使用 MemoryStream、位元組數組和其他記憶體對象，而無需特殊配置或變通方法。
