c# winform 如何在一个button按钮的click事件中 修改当前窗体的size

Answer 1

因为不在同一个实例中.也没关联起来.
最简单的解决方案就是定义为全局.
例如:

private Form fm1;
private Button button;
private TextBox tbd;

private void button1_Click(object sender, EventArgs e)
{
fm1 = new Form();
fm1.StartPosition = FormStartPosition.CenterScreen;
fm1.Size = new System.Drawing.Size(400, 160);
fm1.Text = "测试";

button = new Button();
button.Name = "button";
button.Text = "登陆";
button.Location = new Point(10, 10);
button.Size = new Size(24, 57);
button.Click += button_Click;

tbd = new TextBox();
tbd.Name = "TextBox";
tbd.Text = "测试文本";

tbd.Location = new Point(50, 10);
tbd.Size = new Size(24, 57);

fm1.Controls.Add(tbd);
fm1.Controls.Add(button);

fm1.Show();
}

void button_Click(object sender, EventArgs e)
{
string AA = tbd.Text;
}

Answer 2

点击事件中

this.Size = new Size(宽度, 高度);
