C# 如何在ASP.NET核心Web API中传递int数组

我有以下Web API方法：

[Route("api/[controller]")]
[ApiController]
public class SubjectsController : ControllerBase
{
    [HttpGet("children")]
    public IActionResult GetAllFromChildren([FromQuery]int[] childrenIds)
    {
        // omitted for brevity
    }
}

我试图通过Ajax传递查询字符串来调用它，但我似乎无法让它工作。我的Ajax调用如下所示：

$.ajax({
    url: "/api/subjects/children?childrenIds=1&childrenIds=2&childrenIds=3",
    method: "GET",
    contentType: "application/json; charset=utf-8"
})

[Route("api/[controller]")]
[ApiController]
public class SubjectsController : ControllerBase
{
    [HttpGet("children")]
    public IActionResult GetAllFromChildren([FromQuery(Name="childrenIds")]int[] childrenIds)
    {
        // omitted for brevity
    }
}

$.ajax({
    url: "/api/subjects/children?childrenIds=1&childrenIds=2&childrenIds=3",
    method: "GET",
    contentType: "application/json; charset=utf-8"
})

调用了该方法，但未填充int数组。我做错了什么？

尝试将

Name

添加到

[FromQuery]

，因此代码应该如下所示：

$.ajax({
    url: "/api/subjects/children?childrenIds=1&childrenIds=2&childrenIds=3",
    method: "GET",
    contentType: "application/json; charset=utf-8"
})

[Route("api/[controller]")]
[ApiController]
public class SubjectsController : ControllerBase
{
    [HttpGet("children")]
    public IActionResult GetAllFromChildren([FromQuery(Name="childrenIds")]int[] childrenIds)
    {
        // omitted for brevity
    }
}

$.ajax({
    url: "/api/subjects/children?childrenIds=1&childrenIds=2&childrenIds=3",
    method: "GET",
    contentType: "application/json; charset=utf-8"
})

ajax url如下所示：

$.ajax({
    url: "/api/subjects/children?childrenIds=1&childrenIds=2&childrenIds=3",
    method: "GET",
    contentType: "application/json; charset=utf-8"
})

[Route("api/[controller]")]
[ApiController]
public class SubjectsController : ControllerBase
{
    [HttpGet("children")]
    public IActionResult GetAllFromChildren([FromQuery(Name="childrenIds")]int[] childrenIds)
    {
        // omitted for brevity
    }
}

$.ajax({
    url: "/api/subjects/children?childrenIds=1&childrenIds=2&childrenIds=3",
    method: "GET",
    contentType: "application/json; charset=utf-8"
})

这是我的错别字，我会在问题中编辑，我检查了代码，有一个&。这回答了你的问题吗？
