如何清除winform Mdi窗体的默认边框

Answer 1

C#
有两种办法
1.代码中加 form1.FormBorderStyle = FormBorderStyle.None;//无边框
2.在窗本属性栏找FormBorderStyle选择none

private void Form1_Load(object sender, EventArgs e)
{
this.FormBorderStyle = FormBorderStyle.None;//无边框
}

private void Form1_Paint(object sender, PaintEventArgs e)
{
e.Graphics.DrawRectangle(Pens.DarkOliveGreen, 0, 0, this.Width - 1, this.Height - 1);
}
