Question

我有一个方法名称addDays，它接收月份的第一天和月份的天数。此方法将动态标签添加到表7x6，表7x6表示每周的每个月的每一天。我还为每个标签添加了事件，以便用户可以单击它们。我遇到的问题是我需要能够阅读该人点击的标签。假设我运行应用程序填充我的日历，然后点击本月的第一天，然后我希望能够捕获该标签的文本，即1。这是我的addDays方法的代码。

private void addDays(int day,int totaldays)
    {
            int reset = 0;
            Label newlabel;
            string label;
            int labelnum;
            Console.WriteLine("testoutputbeforebig forloop");
            //DayTableHold.Controls.Add(newlabel, 0, 6);
            int numday = 0;
            for (int coll = 0; coll <= 7; coll++)
            {

                    for (int row = 0; row <=6; row++)
                    {
                        if (numday < totaldays)
                        {
                            newlabel = new Label();
                            newlabel.AutoSize = true;


                            if (row==day &&coll==0)
                            {
                                labelnum = numday + 1;
                                label = labelnum.ToString();
                                newlabel.Text = label;
                                newlabel.Margin = new System.Windows.Forms.Padding(17, 0, 10, 0);
                                newlabel.Click += new System.EventHandler(days_Click);
                                DayTableHold.Controls.Add(newlabel, row, coll);

                                numday++;
                                reset = 1;
                                if (row == 6)
                                {
                                    coll = 1;

                                }
                                else coll = 0;
                                Console.WriteLine("testoutput1 " + numday + " " + label);

                            }
                            else if (reset == 1)
                            {
                                labelnum = numday + 1;
                                label = labelnum.ToString();
                                newlabel.Text = label;
                                newlabel.Margin = new System.Windows.Forms.Padding(17, 0, 10, 0);
                                newlabel.Click += new System.EventHandler(days_Click);
                                DayTableHold.Controls.Add(newlabel, row, coll);
                                numday++;
                                Console.WriteLine("test output2 " + numday + " " + label);
                            }



                        }



                }



        }

    }

这是我点击标签的事件处理程序

    private void days_Click(object sender, EventArgs e)
    {
        //here is were i want to capture the labels of the clicks.  
        count++;
        Console.WriteLine("day was click"+ count);


    } enter code here

您需要在创建Label时与某个事件挂钩，所以在您的行之后：

newLabel = new Label();

您需要为Click事件添加处理程序：

newLabel.Click += new EventHandler(days_Click);

然后，在Click事件处理程序中，您可以从Label对象获取sender：

Label selectedLabel = (Label)sender;
string labelText = selectedLabel.Text;

需要帮助从动态创建的标签中读取标签文本
