Question

我对C＃和整体编程几乎没有经验，所以你可能会发现我的问题很愚蠢。但是，我试图使用代码创建一个Windows窗体，我已经成功完成了我想要的。但现在我想在我的所有按钮上添加按钮点击事件。我想addToDay [i]清除exerciseBox [i]，setBox [i]和repBox [i]中的文本。感谢。

    public NewSchedule2(string path)
    {
        InitializeComponent();
        this.SuspendLayout();

        labels = new System.Windows.Forms.Label[7];
        exercises = new System.Windows.Forms.TextBox[7];
        sets = new System.Windows.Forms.TextBox[7];
        reps = new System.Windows.Forms.TextBox[7];
        addToDay = new System.Windows.Forms.Button[7];

        string[] lines = File.ReadAllLines(path);

        for (int i = 0; i < 7; i++)
        {
            this.labels[i] = new System.Windows.Forms.Label();
            this.labels[i].Location = new System.Drawing.Point(40, 40 + i * 50);
            this.labels[i].Name = "Label" + i;
            this.labels[i].Size = new System.Drawing.Size(110, 20);
            this.labels[i].Text = lines[i];
            this.Controls.Add(this.labels[i]);

            if (lines[i] == "Restday")
            {

            }
            else
            {
                this.exercises[i] = new System.Windows.Forms.TextBox();
                this.exercises[i].Location = new System.Drawing.Point(160, 40 + i * 50);
                this.exercises[i].Name = "excersiceBox" + i;
                this.exercises[i].Size = new System.Drawing.Size(110, 20);
                this.exercises[i].Text = "";
                this.Controls.Add(this.exercises[i]);

                this.sets[i] = new System.Windows.Forms.TextBox();
                this.sets[i].Location = new System.Drawing.Point(290, 40 + i * 50);
                this.sets[i].Name = "setBox" + i;
                this.sets[i].Size = new System.Drawing.Size(40, 20);
                this.sets[i].Text = "";
                this.Controls.Add(this.sets[i]);

                this.reps[i] = new System.Windows.Forms.TextBox();
                this.reps[i].Location = new System.Drawing.Point(350, 40 + i * 50);
                this.reps[i].Name = "repBox" + i;
                this.reps[i].Size = new System.Drawing.Size(40, 20);
                this.reps[i].Text = "";
                this.Controls.Add(this.reps[i]);

                this.addToDay[i] = new System.Windows.Forms.Button();
                this.addToDay[i].Location = new System.Drawing.Point(430, 40 + i * 50);
                this.addToDay[i].Name = "addToDay" + i;
                this.addToDay[i].Click += new System.EventHandler(this.button_Clicked);
                this.addToDay[i].Size = new System.Drawing.Size(80, 20);
                this.addToDay[i].Text = "Add To " + lines[i];
                this.Controls.Add(this.addToDay[i]);
            }
        }
    }

    private void button_Clicked(object sender, EventArgs e)
    {

    }

以下是您可以使用的示例，以实现这一目标。祝你学习愉快：）

   public NewSchedule2(string path)
    {
        InitializeComponent();
        this.SuspendLayout();

        labels = new System.Windows.Forms.Label[7];
        exercises = new System.Windows.Forms.TextBox[7];
        sets = new System.Windows.Forms.TextBox[7];
        reps = new System.Windows.Forms.TextBox[7];
        addToDay = new System.Windows.Forms.Button[7];

        string[] lines = File.ReadAllLines(path);

        for (int i = 0; i < 7; i++)
        {
            this.labels[i] = new System.Windows.Forms.Label();
            this.labels[i].Location = new System.Drawing.Point(40, 40 + i * 50);
            this.labels[i].Name = "Label" + i;
            this.labels[i].Size = new System.Drawing.Size(110, 20);
            this.labels[i].Text = lines[i];
            this.Controls.Add(this.labels[i]);

            if (lines[i] == "Restday")
            {

            }
            else
            {
                this.exercises[i] = new System.Windows.Forms.TextBox();
                this.exercises[i].Location = new System.Drawing.Point(160, 40 + i * 50);
                this.exercises[i].Name = "excersiceBox" + i;
                this.exercises[i].Size = new System.Drawing.Size(110, 20);
                this.exercises[i].Text = "";
                this.Controls.Add(this.exercises[i]);

                this.sets[i] = new System.Windows.Forms.TextBox();
                this.sets[i].Location = new System.Drawing.Point(290, 40 + i * 50);
                this.sets[i].Name = "setBox" + i;
                this.sets[i].Size = new System.Drawing.Size(40, 20);
                this.sets[i].Text = "";
                this.Controls.Add(this.sets[i]);

                this.reps[i] = new System.Windows.Forms.TextBox();
                this.reps[i].Location = new System.Drawing.Point(350, 40 + i * 50);
                this.reps[i].Name = "repBox" + i;
                this.reps[i].Size = new System.Drawing.Size(40, 20);
                this.reps[i].Text = "";
                this.Controls.Add(this.reps[i]);

                this.addToDay[i] = new System.Windows.Forms.Button();
                this.addToDay[i].Location = new System.Drawing.Point(430, 40 + i * 50);
                this.addToDay[i].Name = "addToDay" + i;
                this.addToDay[i].Click += new System.EventHandler(this.button_Clicked);
                this.addToDay[i].Size = new System.Drawing.Size(80, 20);
                this.addToDay[i].Text = "Add To " + lines[i];
                this.addToDay[i].Click += new System.EventHandler(this.button_Clicked);
                this.Controls.Add(this.addToDay[i]);
            }
        }
    }

   private void button_Clicked(object sender, EventArgs e)
    {
        Button triggeredButton = (Button) sender;

        var numAlpha = new Regex("(?<Alpha>[a-zA-Z]*[ _]?)(?<Numeric>[0-9]*)");
        var match = numAlpha.Match(triggeredButton.Name);
        var num = match.Groups["Numeric"].Value;

        this.exercises[num].Text = string.Empty;
        this.sets[num].Text = string.Empty;
        this.reps[num].Text = string.Empty;
    }

这是为按钮添加点击事件的方法：

// btnTest is object of button. This is how you add event for button
btnTest.Click += new System.EventHandler(this.btnButton_Click);

// its event handler

void btnButton_Click(object sender, EventArgs e)
{
 // your code goes here
}

我希望它会对你有所帮助.. :)

Answer 3

这是为每个按钮设置自定义事件的简单方法：

 for (int i = 0; i < 7; i++){
     .
     .
     .
     string text = "some things...";
     this.addToDay[i] = new System.Windows.Forms.Button();
     this.addToDay[i].Click += (object sender, EventArgs e)=>
     {
        //you can use your variables inside event
        MessageBox.ShowDialog(text + i);
     };
 }
