You can send a list of strings in an Ajax call by serializing the list as JSON and passing it as the `data` parameter in the Ajax request. Here's an example:
var list = ["apple", "banana", "orange"];$.ajax({url: "/Controller/Action",type: "POST",data: JSON.stringify(list),contentType: "application/json; charset=utf-8",dataType: "json",success: function(result) {// handle success},error: function(xhr, status, error) {// handle error}});
In this example, the `list` variable contains an array of strings that you want to send to the server. The `$.ajax()` function is then used to send the array to the controller action method.
The `JSON.stringify(list)` function is used to serialize the list as a JSON string that can be sent in the request. The `contentType` parameter is set to `"application/json; charset=utf-8"` to indicate that the data being sent is JSON. The `dataType` parameter is set to `"json"` to indicate that the expected response type is JSON.
In the controller action method, you can receive the list of strings as a parameter. The parameter should be annotated with the `[FromBody]` attribute to indicate that the data is coming from the request body. Here's an example of how to receive the list of strings in the controller action method:
[HttpPost]
public ActionResult ActionName([FromBody] List<string> list)
{
// process the list of strings
return View();
}
In this example, the `ActionName` method is decorated with the `[HttpPost]` attribute to indicate that it should be called when an HTTP POST request is received. The `List<string>` parameter is used to receive the list of strings, and the `[FromBody]` attribute is used to indicate that the data is coming from the request body. You can then process the list of strings as needed and return a view.
