  1. 使用 C# 從數據庫文件中提取數據

    數據庫 被認為是大多數應用程序的組成部分。無論是桌面、Web 還是移動應用程序，數據庫在存儲、訪問和操作數據方面都起著至關重要的作用。有許多數據庫管理系統可以為您創建和管理數據庫。 但是，可能會出現這樣一種情況，即您需要一種方法來從數據庫文件(即 .db 文件)中提取數據，而無需安裝數據庫管理系統或編寫 SQL 查詢。在這種情況下，您將如何解析數據庫文件並從中獲取數據？ 在本文中，我將演示如何在不編寫 SQL 查詢的情況下輕鬆地從 SQLite 數據庫中的表中提取數據。我將使用 GroupDocs.Parser for .NET API，它支持通過 ADO.NET。 從 SQLite 數據庫 (.db) 中的表中提取數據的步驟 在 Visual Studio 中創建一個新項目。 從 NuGet 安裝適用於 GroupDocs.Parser for .NET。 添加以下命名空間。 using System; using System.Collections.Generic; using System.IO; using GroupDocs.Parser.Data; using GroupDocs.Parser.Options; 準備連接字符串。 string connectionString = string.Format("Provider=System.Data.Sqlite;Data Source={0};Version=3;", "sqlite.db"); 在 Parser 對像中加載數據庫文件。 using (Parser parser = new Parser(connectionString, new LoadOptions(FileFormat.Database))) { // 你的代碼在這裡 } 使用 Parser.GetToc 方法獲取數據庫中表的列表。 // 獲取表格列表 IEnumerable toc = parser....Generic; using System.IO; using GroupDocs...
