How to get service from ValidationContext using Simple Injector in C#?

To get service from ValidationContext using Simple Injector in C#, you can follow these steps:

  • First, register the types you want to use with Simple Injector. This can be done using the container's Register method. For example:
container.Register<IValidator<Customer>, CustomerValidator>();
  • Next, create an instance of the ValidatorFactory class, passing in the Simple Injector container as a parameter:
var validatorFactory = new ValidatorFactory(container);
  • Now, in your code where you want to use the ValidationContext, create an instance of the ValidationContext class and pass in the object you want to validate, along with the validatorFactory:
var validationContext = new ValidationContext(customer, null, null); validationContext.InitializeServiceProvider(() => validatorFactory);
  • Finally, you can use the GetService method of the validationContext to get an instance of the validator for the object you want to validate. For example:
var validator = validationContext.GetService(typeof(IValidator<Customer>)) as IValidator<Customer>;

You can then use the validator to perform the validation on the object.
