winform 把主界面分成若干等份

可以使用TableLayoutPanel控件来实现将主界面分成若干等份。

1. 在Visual Studio中创建一个Windows Forms应用程序。
2. 在主窗体中添加一个TableLayoutPanel控件。
3. 将TableLayoutPanel的Dock属性设置为Fill，这样它将填充整个窗体。
4. 在TableLayoutPanel中添加行和列，可以通过右键点击TableLayoutPanel选择“添加行”或“添加列”来实现。
5. 在每个单元格中添加需要的控件，可以通过拖拽控件到TableLayoutPanel中的单元格来实现。
6. 调整每个单元格的大小和位置，可以通过拖拽TableLayoutPanel中的边缘和分隔线来实现。
7. 设置每个单元格的大小比例，可以通过在属性窗口中设置每个行或列的SizeType和Size属性来实现。

示例代码：

private void InitializeComponent()
{
    this.tableLayoutPanel1 = new System.Windows.Forms.TableLayoutPanel();
    this.button1 = new System.Windows.Forms.Button();
    this.button2 = new System.Windows.Forms.Button();
    this.button3 = new System.Windows.Forms.Button();
    this.button4 = new System.Windows.Forms.Button();
    this.tableLayoutPanel1.SuspendLayout();
    this.SuspendLayout();
    // 
    // tableLayoutPanel1
    //

    this.button3.TabIndex = 2;

    this.button3.UseVisualStyleBackColor = true;
    // 
    // button4
    //

    this.button4.Name = "button4";
    this.button4.Size = new System.Drawing.Size(394, 219);
    this.button4.TabIndex = 3;
    this.button4.Text = "Button 4";
    this.button4.UseVisualStyleBackColor = true;
    // 
    // Form1
    // 
    this.AutoScaleDimensions = new System.Drawing.SizeF(8F, 15F);
