Using lambdas to wrap model validations in C#

In .NET, I have found the following method useful when wrapping validation around any CRUD operation: private IEnumerable<ValidationResult> PerformWithModelValidation(object model, Action code_to_execute) { var results = new List<ValidationResult>(); ValidationContext context = new ValidationContext(model, null, null); bool valid = Validator.TryValidateObject(model, context, results, true); if (valid) { code_to_execute(); } return results; } //How to use the method above: PerformWithModelValidation(new_product, () => { MyRepository.Add(new_product); MyRepository.SaveChanges(); } );
