本文介绍了一种用于实现窗体及其子控件在不同分辨率下自适应布局的算法。该算法通过记录控件的位置比例和大小，在窗口大小变化时重新调整控件的位置和尺寸，确保界面元素始终保持合适的位置与比例。

private void formChange() { int count = this.Controls.Count * 2 + 2; int gr1 = this.groupBox1.Controls.Count * 2 + 2; int gr2 = this.groupBox2.Controls.Count * 2 + 2; float[] factor = new float[count + gr1 + gr2]; int i = 0; factor[i++] = Size.Width; factor[i++] = Size.Height; foreach (Control ctrl in this.Controls) { factor[i++] = ctrl.Location.X / (float)Size.Width; factor[i++] = ctrl.Location.Y / (float)Size.Height; ctrl.Tag = ctrl.Size; } foreach (Control ctrl in this.groupBox1.Controls) { factor[i++] = ctrl.Location.X / (float)Size.Width; factor[i++] = ctrl.Location.Y / (float)Size.Height; ctrl.Tag = ctrl.Size; } foreach (Control ctrl in this.groupBox2.Controls) { factor[i++] = ctrl.Location.X / (float)Size.Width; factor[i++] = ctrl.Location.Y / (float)Size.Height; ctrl.Tag = ctrl.Size; } Tag = factor; }

注意窗体里的每个容器都要遍历，记录位置和大小。

在窗体 Resize事件里代码

private void JiuX_Sale_Resize(object sender, EventArgs e) { float[] scale = (float[])Tag; int i = 2; foreach (Control ctrl in this.Controls) { ctrl.Left = (int)(Size.Width * scale[i++]); ctrl.Top = (int)(Size.Height * scale[i++]); ctrl.Width = (int)(Size.Width / (float)scale[0] * ((Size)ctrl.Tag).Width); ctrl.Height = (int)(Size.Height / (float)scale[1] * ((Size)ctrl.Tag).Height); } foreach (Control ctrl in this.groupBox1.Controls) { ctrl.Left = (int)(Size.Width * scale[i++]); ctrl.Top = (int)(Size.Height * scale[i++]); ctrl.Width = (int)(Size.Width / (float)scale[0] * ((Size)ctrl.Tag).Width); ctrl.Height = (int)(Size.Height / (float)scale[1] * ((Size)ctrl.Tag).Height); } foreach (Control ctrl in this.groupBox2.Controls) { ctrl.Left = (int)(Size.Width * scale[i++]); ctrl.Top = (int)(Size.Height * scale[i++]); ctrl.Width = (int)(Size.Width / (float)scale[0] * ((Size)ctrl.Tag).Width); ctrl.Height = (int)(Size.Height / (float)scale[1] * ((Size)ctrl.Tag).Height); } }
