Question

嗨，我想直接从控制器中添加带有模型的数据，而无需执行其他任何操作。

void m(Something a, SomethingElse b, YetAnotherThing c, ANewThing d) {
    // ...
}
// or
void m(Something a, SomethingElse b) {
    // ...
}
// or
void m(ANewThing d) {
    // ...
}

...我希望能够直接从数据库中获取数据：

namespace WebApplication3.Controllers
{

    public class ApiController : Controller
    {
        readonly HumanDBContext _humanContext;

-修复程序在这里：

   [HttpGet]
        public JsonResult Godaddy()
        {

和

   public class ApiController : Controller
    {        private readonly HumanDBContext _db;

您可以执行以下操作：

public jsonResult Get()
{
  DbCommand cmd = _humanContext.DbContext.Database.GetDbConnection().CreateCommand()
 cmd.CommandText = "yourspName";
 cmd.CommandType = CommandType.StoredProcedure;


using (IDataReader reader = await cmd.ExecuteReaderAsync())
{
 List<Foo> items= reader.Select(r => r.GetYourPocoClassModel()).ToList();

string rItems = JsonConvert.SerializeObject(items, Formatting.Indented,
   new JsonSerializerSettings
   {
       ReferenceLoopHandling = ReferenceLoopHandling.Ignore
    });
 return rItems;
 }
}

和GetYourPocoClassModel用于对数据建模：

public Calss HelperExtension
{
   public static Foo GetYourPocoClassModel(this IDataReader r)
   {
    return new Foo
    {
      Id=r["Id"] is DBNull ? 0 : Convert.ToDouble(r["Id"]),
    }
 }
}

EFcore将数据从控制器添加到数据库
