已经包含了一个定义 [英] Already contains a definition for

问题描述

我有一个名为分配和

    private int SeatNumber;

    public Assign(int SeatNum)
    {
        SeatNumber = SeatNum;
    }

    public int SeatNumber
    {
        get { return SeatNumber; }
        set { SeatNumber = value; }

    }

我不知道为什么我收到以下错误

I have no idea why I am getting the following error

e下键入'WindowsFormsApplication1.Assign'已经包含了'SeatNumber的定义

EThe type 'WindowsFormsApplication1.Assign' already contains a definition for 'SeatNumber'

什么是错的？

推荐答案

你在这里两次声明相同的变量。

You're declaring the same variable twice here.

private int SeatNumber;
public int SeatNumber
{
    get { return SeatNumber; }
    set { SeatNumber = value; }

}

这代码定义两次相同的变量。如果您使用.NET 3.0+，你可以做自动实现属性像这样没有私人诠释SeatNumber ：

That code defines the same variable twice. If you're using .net 3.0+, you can do auto-implemented properties like this with no private int SeatNumber:

public int SeatNumber
{
    get;
    set;
}

否则，你应该这样做：

otherwise, you should do this:

private int SeatNumber_;
public int SeatNumber
{
    get { return SeatNumber_; }
    set { SeatNumber_ = value; }
}
