NeoFileMagic

安全、輕量、資源可控的 .NET 多格式檔案讀取器(目前支援 ODS)。適用於需要嚴格資源限制與資料安全驗證的結構化資料提取場景。
專案架構
- NeoFileMagic(類別庫): 核心檔案讀取框架與公開 API(內含 ODS 模組)。
- NeoFileMagic.Tests(測試): xUnit 測試專案,驗證解析正確性與資源限制邊界。
- Sample(範例): 示範如何從本機或遠端載入 ODS 並進行強型別反序列化。
安裝
dotnet add package NeoFileMagic
基本使用
using NeoFileMagic.FileReader.Ods;
// 從檔案載入 ODS
var doc = NeoOds.Load("sample.ods");
// 讀取第一個工作表的 (0,0) 儲存格
var cell = doc.Sheets[0].GetCell(0, 0);
Console.WriteLine(NeoOds.OneLine(cell));
使用範例
1) 遍歷列與欄
using NeoFileMagic.FileReader.Ods;
var doc = NeoOds.Load("sample.ods");
var sheet = doc.Sheets[0];
for (int r = 0; r < sheet.RowCount; r++)
{
var row = sheet.Rows[r];
for (int c = 0; c < row.ColumnCount; c++)
{
var cell = row.Cells[c];
// 以單行輸出:將換行與 Tab 摺疊為單一空白
Console.Write(NeoOds.OneLine(cell));
Console.Write('\t');
}
Console.WriteLine();
}
2) 安全與資源限制設定
using NeoFileMagic.FileReader.Ods;
var options = new OdsReaderOptions
{
// 偵測到檔案加密時拋出 NotSupportedException
ThrowOnEncrypted = true,
// 資源限制:避免異常或惡意檔案造成記憶體壓力 (DoS 攻擊防禦)
MaxSheets = 64,
MaxRowsPerSheet = 100_000,
MaxColumnsPerRow = 256,
MaxRepeatedRows = 100_000,
MaxRepeatedColumns = 256,
};
var doc = NeoOds.Load("sample.ods", options);
3) 強型別模型反序列化
嚴格依表頭(或 [JsonPropertyName])對應欄位,欄位順序、缺漏或格式錯誤會拋出具體例外。反序列化內部使用高效能的 System.Text.Json 進行。
using System.Text.Json.Serialization;
using NeoFileMagic.FileReader.Ods;
public sealed class Person
{
[JsonPropertyName("姓名")]
[JsonPropertyOrder(0)]
public string Name { get; set; } = string.Empty;
[JsonPropertyName("年齡")]
[JsonPropertyOrder(1)]
public int Age { get; set; }
}
var doc = NeoOds.Load("people.ods");
var sheet = doc.Sheets[0];
var list = NeoOds.DeserializeSheetOrThrow<Person>(sheet);
// list 為反序列化結果。若欄位順序或型別不符會拋出 Ods* 相關例外。
4) 從遠端 URL 載入(非同步)
using NeoFileMagic.FileReader.Ods;
var doc = await NeoOds.LoadFromUrlAsync("https://example.com/data.ods");
開發與驗證
1) 建置與測試
dotnet restore
dotnet build
dotnet test
2) 程式碼格式化
# 自動套用專案程式碼風格
dotnet format
# 驗證格式(不修改檔案)
dotnet format --verify-no-changes
