SecureFileValidator
📦 強型別檔案簽章驗證器，支援 .NET 8 / .NET Framework 4.7
支援 DataAnnotation、Action Filter 驗證方式，可套用於 ASP.NET Core / MVC 控制器與表單檢查。
✅ 支援格式（依 magic number 檢查）
.jpg,.jpeg,.png,.gif,.bmp,.tif.pdf,.docx,.xlsx,.zip,.rar,.7z.mp3,.mp4,.avi,.webp,.exe
🔐 驗證方式
1. DataAnnotation 驗證（ASP.NET Core）
public class UploadModel
{
[ValidateFileSignature(AllowedExtensions = new[] { ".docx", ".xlsx" })]
public IFormFile File { get; set; }
}
驗證失敗會寫入 ModelState 錯誤，可搭配
TryValidateModel()或TryUpdateModelAsync()使用。
2. Action Filter 驗證（ASP.NET Core）
[ValidateFileSignature(FileParameterName = "file")]
public IActionResult Upload(IFormFile file) { ... }
或驗證所有表單中檔案：
[ValidateFileSignature]
public IActionResult Upload() { ... }
3. MVC (.NET Framework)
[ValidateFileSignature(FileParameterName = "file", AllowedExtensions = new[] { ".docx" })]
public ActionResult Upload(HttpPostedFileBase file)
🧪 單元測試
請見 SecureFileValidator.Tests 中範例，包括：
.png冒充.docx驗證失敗- 合法
.docx驗證成功 - 驗證失敗時
ModelState錯誤訊息檢查
