Usage

⚙️Using IFormFile on ActionMethod

  public async Task<IActionResult> OnPostUploadAsync(IFormFile file)
  {
      /*By default it validates all the files like Documents,Images, Videos, Audios*/
      bool isValid = file.IsValidFile();
      if(isValid){
          var filePath = Path.GetTempFileName();
          await file.CopyToAsync(File.OpenWrite(filePath));
          return Ok(new { message = "File uploaded successfully." });
      }
      return BadRequest(new {message = "Invalid file"});
      
  }

⚙️Using the FileInfo Class

var fileInfo = new FileInfo("C:/mypath/document.pdf");
var isValid = fileInfo.IsValidFile();
//If you want to only validate the Images then you can pass the allowed FileType[] parameter.
var checkValidImage = fileInfo.IsValidFile(new FileType[] { FileType.Image })

⚙️Updating the default configuration (add/remove allowed extensions & MIME types)

var fileInfo = new FileInfo("C:/mypath/document.pdf");

//If you want to allow json documents then update the configuration
var fileValidatorConfig = new FileValidatorConfiguration();
fileValidatorConfig.DocumentFileExtensins.Add(".json");
fileValidatorConfig.DocumentMimeTypes.Add("application/json");
FileValidatorExtension.UpdateDefaultConfiguration(fileValidatorConfig);

var isValid = fileInfo.IsValidFile(); //Returns true

//If you want to remove any existing valid extension then you can remove the extension from the configuration
fileValidatorConfig.ImmageFileExtensions.Remove(".gif"); //This will return false on any gif file.
FileValidatorExtension.UpdateDefaultConfiguration(fileValidatorConfig);
