c# - 链接按钮单击事件由于其保护级别而无法访问

Question

我正在做一个项目。我正在动态创建一个 asp 表，并在表格单元格中根据条件添加链接按钮。但是在将 Click 事件添加到链接按钮时，它给出了一个错误提示-

System.Web.UI.WebControls.LinkButton.OnClick(System.EventArgs)' is inaccessible due to its protection level

下面是我制作表格的代码

protected void Page_Load(object sender, EventArgs e)
{       
    if(!IsPostBack)
    {         
      setmonthname();
    }
     makeCalendar();
}
public void makeCalendar()
{
    tblcalendar.Rows.Clear();
    //for current month
    DateTime startingdate = StartDateOfMonth(DateTime.Now.AddMonths(monthclickedno));
    DateTime enddate = EndDateOfMonth(DateTime.Now.AddMonths(monthclickedno));
    string startingday = startingdate.DayOfWeek.ToString();
    int startingdayno = Convert.ToInt32(startingdate.DayOfWeek);
    string endday = enddate.DayOfWeek.ToString();//like saturday is 6,stating is from monday with 1 and ending si sunday with 7
    int enddayno = Convert.ToInt32(enddate.DayOfWeek);
    //for prevoius month
    DateTime enddateprevious = (EndDateOfMonth(DateTime.Now.AddMonths(monthclickedno)));
    //for next month
    DateTime startingdatenext = StartDateOfMonth(DateTime.Now.AddMonths(1));
    DateTime dtstart=startingdate.AddDays(-(startingdayno+1));
    //sMonthName = "January";
    //int iMonthNo = Convert.ToDateTime("01-" + sMonthName + "-2011").Month; 
    for (int i = 0; i <7;i++)

                    ctCell.Controls.Add(lnkevent);
                }

                tr.Cells.Add(ctCell);
            }

            tblcalendar.Rows.Add(tr);
        }
    }
}
public void test(object sender,EventArgs e)
{
    Response.Write("helloo");
}

请帮我解决这个问题

正确的订阅应该是这样的:

lnkevent.Click += test;

OnClick 是类内部使用的引发事件的方法。相反，您应该订阅事件本身。
