C# 的窗体最小化和最大化代码

//1.最小化 WindowState = FormWindowState.Minimized; //最小化时隐藏窗体 this.Visible=false; //2.最大化 WindowState == FormWindowState.Maximized; //其实你可以在属性中设置，更方便简单

C# 窗体最大化，最小化，还原 的代码

设置为none后窗体已经没有了标题栏，窗体的移动、最大化、最小化、关闭这些需要自己写代码来完成。

窗体的移动：

bool formMove = false;//窗体是否移动

Point formPoint;//记录窗体的位置

private void Form4_MouseDown(object sender, MouseEventArgs e)//鼠标按下

{

formPoint = new Point();

int xOffset;

int yOffset;

if (e.Button == MouseButtons.Left)

{

xOffset = -e.X - SystemInformation.FrameBorderSize.Width;

yOffset = -e.Y - SystemInformation.CaptionHeight - SystemInformation.FrameBorderSize.Height;

formPoint = new Point(xOffset, yOffset);

formMove = true;//开始移动

}

}

private void Form4_MouseMove(object sender, MouseEventArgs e)//鼠标移动

{

if (formMove == true)

{

Point mousePos = Control.MousePosition;

mousePos.Offset(formPoint.X, formPoint.Y);

Location = mousePos;

}

}

private void Form4_MouseUp(object sender, MouseEventArgs e)//鼠标松开

{

if (e.Button == MouseButtons.Left)//按下的是鼠标左键

{

formMove = false;//停止移动

}

}

窗体的最大化、最小化和关闭：

需要自己拖三个picturebox控件到窗体的右上角，最大化、最小化和关闭的图标就自己去找了。添加picturebox的单击事件。如果要实现一些特效可以加入picturebox的MouseEnter、MouseLeave事件来更换图片。

private void pictureBox1_Click(object sender, EventArgs e)

{

this.WindowState=FormWindowState.Minimized;//最小化

}

private void pictureBox2_Click(object sender, EventArgs e)

{

WindowState = FormWindowState.Maximized;//最大化

}

private void pictureBox3_Click(object sender, EventArgs e)

{

this.Close();

}
