c#窗体分区域

C# 窗体可以使用 Panel 控件来实现分区域布局。Panel 控件是一个容器控件，可以包含其他控件，它可以按照指定的布局方式排列内部的控件。

以下是一个简单的例子，演示了如何将窗体分成两个区域：

1. 在窗体上添加两个 Panel 控件，分别命名为 panelLeft 和 panelRight。
2. 设置 panelLeft 的 Dock 属性为 Left，设置 panelRight 的 Dock 属性为 Fill。
3. 在 panelLeft 中添加需要显示的控件，例如 Label、Button 等。
4. 在 panelRight 中添加需要显示的控件，例如 TextBox、DataGridView 等。

代码如下：

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
}

在 Designer.cs 中：

private System.Windows.Forms.Panel panelLeft;
private System.Windows.Forms.Panel panelRight;
private System.Windows.Forms.Label label1;
private System.Windows.Forms.TextBox textBox1;
private System.Windows.Forms.Button button1;
private System.Windows.Forms.DataGridView dataGridView1;

private void InitializeComponent()
{
    this.panelLeft = new System.Windows.Forms.Panel();
    this.panelRight = new System.Windows.Forms.Panel();
    this.label1 = new System.Windows.Forms.Label();
    this.textBox1 = new System.Windows.Forms.TextBox();
    this.button1 = new System.Windows.Forms.Button();
    this.dataGridView1 = new System.Windows.Forms.DataGridView();
    this.panelLeft.SuspendLayout();
    this.panelRight.SuspendLayout();
    ((System.ComponentModel.ISupportInitialize)(this.dataGridView1)).BeginInit();
    this.SuspendLayout();

    // 
    // panelLeft
    // 
    this.panelLeft.Controls.Add(this.button1);
    this.panelLeft.Controls.Add(this.textBox1);
    this.panelLeft.Controls.Add(this.label1);
    this.panelLeft.Dock = System.Windows.Forms.DockStyle.Left;
    this.panelLeft.Location = new System.Drawing.Point(0, 0);
    this.panelLeft.Name = "panelLeft";
    this.panelLeft.Size = new System.Drawing.Size(200, 450);
    this.panelLeft.TabIndex = 0;
    // 
    // panelRight
    // 
    this.panelRight.Controls.Add(this.dataGridView1);
    this.panelRight.Dock = System.Windows.Forms.DockStyle.Fill;
    this.panelRight.Location = new System.Drawing.Point(200, 0);
    this.panelRight.Name = "panelRight";
    this.panelRight.Size = new System.Drawing.Size(600, 450);
    this.panelRight.TabIndex = 1;

    // 
    // label1
    // 
    this.label1.AutoSize = true;
    this.label1.Location = new System.Drawing.Point(12, 18);
    this.label1.Name = "label1";
    this.label1.Size = new System.Drawing.Size(56, 17);
    this.label1.TabIndex = 0;
    this.label1.Text = "Label1";
    // 
    // textBox1
    // 
    this.textBox1.Location = new System.Drawing.Point(15, 53);
    this.textBox1.Name = "textBox1";
    this.textBox1.Size = new System.Drawing.Size(165, 22);
    this.textBox1.TabIndex = 1;
    // 
    // button1
    // 
    this.button1.Location = new System.Drawing.Point(15, 94);
    this.button1.Name = "button1";
    this.button1.Size = new System.Drawing.Size(75, 23);
    this.button1.TabIndex = 2;
    this.button1.Text = "Button1";
    this.button1.UseVisualStyleBackColor = true;
    // 
    // dataGridView1
    // 
    this.dataGridView1.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
    this.dataGridView1.Location = new System.Drawing.Point(22, 18);
    this.dataGridView1.Name = "dataGridView1";
    this.dataGridView1.RowTemplate.Height = 24;
    this.dataGridView1.Size = new System.Drawing.Size(544, 409);
    this.dataGridView1.TabIndex = 0;

    // 
    // Form1
    // 
    this.AutoScaleDimensions = new System.Drawing.SizeF(8F, 16F);
    this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
    this.ClientSize = new System.Drawing.Size(800, 450);
    this.Controls.Add(this.panelRight);
    this.Controls.Add(this.panelLeft);
    this.Name = "Form1";
    this.Text = "Form1";
    this.panelLeft.ResumeLayout(false);
    this.panelLeft.PerformLayout();
    this.panelRight.ResumeLayout(false);
    ((System.ComponentModel.ISupportInitialize)(this.dataGridView1)).EndInit();
    this.ResumeLayout(false);
