JsonResult在ASP.NET CORE 2.1中返回Json

在asp.net-core-2.1

Controllerbase

中没有

Json(Object)

方法。但是

Controller

确实如此。

因此，要么将当前控制器重构为

Controller

public class GraficResourcesApiController : Controller {    //...}

可以访问该

Controller.Json

方法，或者您可以

JsonResult

在 *** 作中初始化一个新的自己

return new JsonResult(rows);

这基本上是该方法在内部执行的 *** 作

Controller

/// <summary>/// Creates a <see cref="JsonResult"/> object that serializes the specified <paramref name="data"/> object/// to JSON./// </summary>/// <param name="data">The object to serialize.</param>/// <returns>The created <see cref="JsonResult"/> that serializes the specified <paramref name="data"/>/// to JSON format for the response.</returns>[NonAction]public virtual JsonResult Json(object data){    return new JsonResult(data);}/// <summary>/// Creates a <see cref="JsonResult"/> object that serializes the specified <paramref name="data"/> object/// to JSON./// </summary>/// <param name="data">The object to serialize.</param>/// <param name="serializerSettings">The <see cref="JsonSerializerSettings"/> to be used by/// the formatter.</param>/// <returns>The created <see cref="JsonResult"/> that serializes the specified <paramref name="data"/>/// as JSON format for the response.</returns>/// <remarks>Callers should cache an instance of <see cref="JsonSerializerSettings"/> to avoid/// recreating cached data with each call.</remarks>[NonAction]public virtual JsonResult Json(object data, JsonSerializerSettings serializerSettings){    if (serializerSettings == null)    {        throw new ArgumentNullException(nameof(serializerSettings));    }    return new JsonResult(data, serializerSettings);}
