推荐答案

您可能想使用包含数据的模型:

You might want to use a model which contains your data:

public class A1
{
    public int id { get; set; }
    public string name { get; set; }
}

public class A2
{
    public int id2 { get; set; }
    public string name2 { get; set; }
}

public class AModel 
{
    public A1 Emp { get; set; }
    public A2 EmpMarks { get; set; }
}


[Route("Save")]
[HttpPost]
public string Save(AModel aData)
{
    // ... your logic here
}
