Binding a value of 1 as true for a boolean for WebApi

Question

I have a PHP program POSTING to a C# MVC WebApi. The WebApi program starts as:

public async Task<IHttpActionResult> EmailExists(UsersEmailExistsBindingModel model)
{
    if (!ModelState.IsValid)
    {
        return BadRequest(ModelState);
    }
    /* remaining functionality */
}

The binding model as as follows:

public class UsersEmailExistsBindingModel 
{
    [Required]
    public string UserId { get; set; }

    [Required]
    public string Email { get; set; }

    public bool Update { get; set; }
}

The Update property represents if this is for an existing user or not. i.e Are we doing an update?

When PHP posts the request, it uses Update=1 in the form content, which returns The value '1' is not valid for Update.

How can I specify that 1 and 0 should be accepted as valid values for true and false for the boolean value when binding?

Answer 1

You can either

1. Add a property with short, and then your bool property wrapping the short property.

2. Implement a CustomValueProvider see: How to map a 1 or 0 in an ASP.Net MVC route segment into a Boolean action method input parameter
