What should be the receiving type in the controller?

Question

JavaScript

js script sends post request to asp.net controller
$.post("/Home/Add" , {"A":"a" , "B":"b"});

[HttpPost]
   public void Add(/*.....*/) {}

What should be the type of the receiving parameter in the Add function in order to accept an array from javascript?

Answer 1

It must be a class with the same properties as you are sending, and the [FromBody] attribute must be added:

public class Word
{
public string A { get; set; }
public string B { get; set; }
}

[HttpPost]
public void Add([FromBody]Word word)
{

}

Sending an object is more difficult:

public class TestClass
{
      public int Prop { get; set; }
}

public class Word
{
public TestClass A{ get; set; }
public string B { get; set; }
}

[HttpPost]
public void Add([FromBody]Word word)
{

}

Array:

public class Word
{
       public string A{ get; set; }
}

[HttpPost]
public void Add([FromBody]IEnumerable<Word> words)
{

}

Use different naming properties on behalf of:

public class Word
{
       [JsonProperty("OtherName")]
       public string A{ get; set; }
}

[HttpPost]
public void Add([FromBody]IEnumerable<Word> words)
{

}
