解决方案

这是如何添加点击事件按钮：

  //为btnTest是按钮的对象。这是你如何为按钮添加事件
btnTest.Click + =新System.EventHandler（this.btnButton_Click）;//它的事件处理程序无效btnButton_Click（对象发件人，EventArgs的发送）
{
 //你的code到这里
}
 

我希望它会帮助你..：）

I have almost 0 experience with C# and programming overall, so you might find my question stupid. However, Im trying to create a Windows Form using code and I've succeeded with what I've wanted. But now I would like to add button click events to all my buttons. I want addToDay[i] to clear text in exerciseBox[i], setBox[i] and repBox[i]. Thanks.

    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)
    {

    }
}

解决方案

This is how you can add click events for buttons:

// 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
}

I hope it will help you.. :)
