如何总结行中单独列中字段的值？

public class Ball    
{    
    public int BallId { get; set; }
    public int Ball1 { get; set; }
    public int Ball2 { get; set; }
    public int Ball3 { get; set; }

    public int Summa {
        get {return Ball1 + Ball2;}
        private set { }
    }

Answer 1

创建单独的部分调用并定义您的属性。

public partial class Ball    
{        

    public int Summa {
        get {return Ball1 + Ball2;}
        private set { }
    }
