ModelStateValidationFilter

The ModelStateValidationFilter is a simple wrapper that returns a BadRequestObjectResult with an ApiError body when the passed ModelState of an action is invalid. This allows to keep controlls free of basic model state validation logic.

To use the filter, it must be configured in the AddMvc() call in ConfigureServices:

services.AddMvc(options =>
    {
        options.Filters.Add(typeof(ModelStateValidationFilter));
    })

RequiredFormFileValidationFilter

The RequiredFormFileValidationFilter is a simple wrapper that returns a BadRequestObjectResult with an ApiError body when the invoked Controller action as paramaters of type IFormFile that are annotated with [Required] but have no value bound.

For example, the following action makes use of the filter:

[HttpPost("RequiredFormFile")]
public IActionResult RequiredFormFile([Required]IFormFile formFile)
{
    return Ok();
}

To use the filter, it must be configured in the AddMvc() call in ConfigureServices:

services.AddMvc(options =>
    {
        options.Filters.Add(typeof(RequiredFormFileValidationFilter));
    })
