ASP.NET Core API 获取错误：&#39;EntityEntry<Vehicle> &#39; 不包含定义

Question

I migrated my project from ASP.NET to ASP.NET Core, and my post request method now shows an error for all three entries:

CS1061: 'EntityEntry' does not contain a definition for 'plateno' and no accessible extension method 'plateno' accepting a first argument of type 'EntityEntry' could be found (are you missing a using directive or an assembly reference?)

My code is:-

nobleappDbContext.vehicles.Add(vehicle).plateno = vehicle.plateno;
nobleappDbContext.vehicles.Add(vehicle).description = vehicle.description;
nobleappDbContext.vehicles.Add(vehicle).status = 1;
               
nobleappDbContext.SaveChanges();
return StatusCode(HttpStatusCode.Created);

Answer 1

You are providing the vehicle for insertion, in which the variable contains the value for plateno and description properties.

For status property, just assign the value to the vehicle instance.

In short, the code should be looked as:

// Initialize & assign value for vehicle 
vehicle.status = 1;

nobleappDbContext.vehicles.Add(vehicle);
               
nobleappDbContext.SaveChanges();
