Question

我有这样的PHP代码，我需要将其转换为.NET

function jaktDate2()
{
Global $nameofselectbox,$startYear,$endYear,$year,
$startDate,$endDate,$startMounth,$endMounth,$startDay,$endDay;
$today = getdate();
$year=$today['year'];
$mounth=$today['mon'];
$day=$today['mday'];
//$year="2004";
//$mounth="7";
//$day="1";

if(round($mounth)<="6"){$startYear=$year-1;$startMounth="-07";$startDay="-01";
$endYear=$year;$endMounth="-06";$endDay="-30";}
elseif(round($mounth)>="7"){$startYear=$year;$startMounth="-07";$startDay="-01";
$endYear=$year+1;$endMounth="-06";$endDay="-30";}

$startDate=$startYear.$startMounth.$startDay;
$endDate=$endYear.$endMounth.$endDay;

return $startDate.";".$endDate;
}

这是我的转换：

  public class HuntingDate
    {
        public string StartYear;
        public string EndYear;
        public string Year;
        public DateTime StartDate;
        public DateTime EndDate;
        public string StartMonth;
        public string EndMonth;
        public DateTime StartDay;
        public DateTime EndDay;

        private string _startYear;
        public string StartYear
        {
            get { return _startYear;}
            set { _startYear = value;}
        }

        private string _endYear;
        public string EndYear
       {
        get{return _endYear;}
        set { _endYear = value; }
       }


        private DateTime _startDate;
        public DateTime StartDate
        {
            get { return _startDate;}
            set { _startDate = value;}
        }

        private DateTime _endDate;
        public DateTime EndDate
        {
            get { return _endDate;}
            set { _startDate = value;}
        }

        private string _year;
        public string Year
        {
            get { return _year;}
            set { _year = value;}
        }


        private string _startMonth;
        public string StartMonth
        {
            get { return _startMonth;}
            set { _startMonth = value;}
        }

        private string _endMonth;
        public string EndMonth
        {
        get { return _endMonth;}
        set { _endMonth = value;}
        }

        private DateTime _startDay;
        public DateTime StartDay
        {
            get { return _startDay;}
            set { _startDay = value;}
        }

        private DateTime _endDay;
        public DateTime EndDay
        {
            get { return _endDay; }
            set { _endDay = value; }
        }

        public HuntingDate(){
        DateTime today = DateTime.Now;
        int year = today.Year;
        int month = today.Month;
        DateTime day = today;

        DateTime StartDate = (StartYear+StartMonth+StartDay);
        DateTime EndDate   = (EndYear+EndMonth+EndDay);

        if (month <= 6)
        {
            //string StartYear = Convert.ToString(year-1);
            string StartYear = (year - 1).ToString();
            string StartMonth = Convert.ToString(7);
            string EndYear = Convert.ToString(year);
            string EndMonth = Convert.ToString(6);
            string EndDay = Convert.ToString(30);
        }
        else if(month >= 7)

        {
            string StartYear =Convert.ToString(year);
            string StartMonth = Convert.ToString(7);
            string StartDay = Convert.ToString(1);
            string EndYear = Convert.ToString(year+1);
            string EndMonth = Convert.ToString(6);
            string EndDay = Convert.ToString(30);

        }
        }
        }

        }

我在这里找到的问题：

        DateTime StartDate = (StartYear+StartMonth+StartDay);
        DateTime EndDate   = (EndYear+EndMonth+EndDay);

问题是：此成员定义不止一次

在这里红色下划线的startyear startmonth startday＆amp;还有其他部分。

Answer 1

由于您已定义公开字段StartDate和属性StartDate，因此无法执行此操作

public DateTime StartDate;

public DateTime StartDate
        {
            get { return _startDate;}
            set { _startDate = value;}
        }

如果您只想使用StartDate作为属性，那么您可以摆脱公共字段，即public DateTime StartDate;。

您似乎正在针对每个公共字段定义属性。这是一个语法错误。您可以删除所有公共字段，因为您没有在属性中执行任何操作，您可以将它们定义为：

public DateTime StartDate { get; set; }

Answer 2

以StartYear为例：

// Field declaration
public string StartYear;

// Property declaration with the same name
public string StartYear
{
    get { return _startYear;}
    set { _startYear = value;}
}

为什么你有公共字段，因为你还获得了公共属性支持的私有字段？摆脱那些公共领域。

更广泛地说，我不会尝试从另一个平台执行逐字的代码端口 - 我会尝试找出意图，然后在您的内容中以惯用的方式实现.NET代码。

Answer 3

您之前已经宣布过StartDate。您正试图在显示错误的部分重新声明它。

这个成员被定义不止一次，但为什么？
