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.. :)

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);
};
}
