                stop() {

但是我想按名称而不是ID进行搜索

namespace product2.Controllers
{
public class ProductsController : ApiController
{
    Product[] products = new Product[]
    {
        new Product { Id = 1, Name = "Tomato Soup", Category = "Groceries", Price = 1 },
        new Product { Id = 2, Name = "Yo-yo", Category = "Toys", Price = 3.75M },
        new Product { Id = 3, Name = "Hammer", Category = "Hardware", Price = 16.99M }
    };

    public IEnumerable<Product> GetAllProducts()
    {
        return products;
    }

    public IHttpActionResult GetProduct(int id)
    {
        var product = products.FirstOrDefault((p) => p.Id == id);
        if (product == null)
        {
            return NotFound();
        }
        return Ok(product);
    }
}
}

不起作用，我怀疑是product.FirstOrDefault是问题的一部分，但是我已经尝试过products.Any，但是当我单击时，它仅显示未定义的$ undefined（function formatItem（item）{ 返回item.Name +'：$'+ item.Price; }）

检查您的WepApiConfig.cs

确保它具有

 public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: 
"api/{controller}/{name}",
            defaults: new { name = RouteParameter.Optional }
        );
    }

这是您的ProductsController

  public IHttpActionResult GetProduct(string name)
    {
        var product = products.FirstOrDefault((p) => p.Name == name);
        if (product == null)
        {
            return NotFound();
        }
        return Ok(product);
    }

然后使用原始文件作为您的index.html

 $(document).ready(function () {
  // Send an AJAX request
  $.getJSON(uri)
      .done(function (data) {
        // On success, 'data' contains a list of products.
        $.each(data, function (key, item) {
          // Add a list item for the product.
          $('<li>', { text: formatItem(item) }).appendTo($('#products'));
        });
      });
});

function formatItem(item) {
  return item.Name + ': $' + item.Price;
}

function find() {
  var id = $('#prodId').val();
  $.getJSON(uri + '/' + id)
      .done(function (data) {
        $('#product').text(formatItem(data));
      })
      .fail(function (jqXHR, textStatus, err) {
        $('#product').text('Error: ' + err);
      });
}

按名称搜索，而不是ID，C＃
