Short version of adding a control to a container (Buttonused as example):
向容器添加控件的简短版本（Button用作示例）：
Button myButton = new Button();
myButton.Text = "some text";
// attach event handler for Click event
// (assuming ButtonClickHandler is an existing method in the class)
myButton.Click += ButtonClickHandler;
myPanel.Controls.Add(myButton);
// additional code for setting location and such for myButton
The tricky part will probably not be to create the controls and add them to the container, but to arrange them so that it looks good.
棘手的部分可能不是创建控件并将它们添加到容器中，而是排列它们以使其看起来不错。

另一个例子添加 5 按钮
int xlocation = 5;
for (int i = 1; i <= 5; i++)
{
Button newButton = new Button();
{
newButton.Name = string.Format("Button{0}", i);
newButton.Text = string.Format("Button {0}",i);
newButton.Location = new System.Drawing.Point(xlocation, 10);
newButton.Size = new System.Drawing.Size(75, 35);
newButton.Click += btn_msg;
this.Controls.Add(newButton);
}
xlocation = xlocation + 85;
}
button click Event
按钮点击事件
public void btn_msg(object sender, EventArgs e)
{
Button btn = (Button)sender;
conn.msgErr(btn.Name.ToString());
}
