字段启动器不能引用非静态字段？错误 [英] A field initiator cannot reference the non-static field? Error

问题描述

  protected   void  Page_Load（对象发​​件人，EventArgs e）
 {
 
 
 
 
  double  startCounter = Convert.ToDouble（DateTime.Now.TimeOfDay.TotalSeconds）; 
  if （！IsPostBack）
 {
} 
} 
  double  endCounter = Convert.ToDouble（DateTime.Now.TimeOfDay.TotalSeconds）; 
  double  totalSeconds = Convert.ToDouble（endCounter  -  startCounter）; 
 Response.Write（totalSeconds）; 
 
} 

请帮帮我

解决方案

< blockquote>这些行

  double  endCounter = Convert.ToDouble（DateTime.Now.TimeOfDay.TotalSeconds）; 
  double  totalSeconds = Convert.ToDouble（endCounter  -  startCounter）; 
 Response.Write（totalSeconds）; 

不在方法范围内，将它们移入;

 受保护  void  Page_Load（ object  sender，EventArgs e）
 {
  double  startCounter = Convert.ToDouble（DateTime.Now.TimeOfDay.TotalSeconds）; 
  if （！IsPostBack）
 {
} 
  double  endCounter = Convert.ToDouble（DateTime.Now.TimeOfDay.TotalSeconds）; 
  double  totalSeconds = Convert.ToDouble（endCounter  -  startCounter）; 
 Response.Write（totalSeconds）; 
} 

希望这会有所帮助，

protected void Page_Load(object sender, EventArgs e)
    {




       double startCounter = Convert.ToDouble(DateTime.Now.TimeOfDay.TotalSeconds);
        if (!IsPostBack)
        {
        }
    }
    double endCounter = Convert.ToDouble(DateTime.Now.TimeOfDay.TotalSeconds);
    double totalSeconds = Convert.ToDouble( endCounter -  startCounter);
        Response.Write(totalSeconds);

}

please help me

解决方案

These lines

double endCounter = Convert.ToDouble(DateTime.Now.TimeOfDay.TotalSeconds);
double totalSeconds = Convert.ToDouble( endCounter -  startCounter);
Response.Write(totalSeconds);

Are not inside the scope of the method, move them in;

protected void Page_Load(object sender, EventArgs e)
{
  double startCounter = Convert.ToDouble(DateTime.Now.TimeOfDay.TotalSeconds);
  if (!IsPostBack)
  {
  }
  double endCounter = Convert.ToDouble(DateTime.Now.TimeOfDay.TotalSeconds);
  double totalSeconds = Convert.ToDouble( endCounter -  startCounter);
  Response.Write(totalSeconds);
}

Hope this helps,
Fredrik
