问题描述

我想将 Form 渲染为位图...在 .net 2.0 中可以吗?

I would like to render Form to bitmap... Is it possible in .net 2.0?

推荐答案

当然，您可以调用 Control.DrawToBitmap() 将控件呈现为位图.对于更一般的绘图，您可以创建一个 Bitmap，然后使用 Graphics.FromImage() 创建一个 Graphics 实例.然后，您可以照常绘制到此图形实例.

Sure, you can call Control.DrawToBitmap() to render a control to a bitmap. For more general drawing, you can create a Bitmap and then use Graphics.FromImage() to create a Graphics instance. You can then draw to this graphics instance as normal.

这是一个可以自己绘制的简单表单(只需添加一个按钮并双击它即可添加 Click 事件处理程序:

Here's a simple form that can draw itself (just add a button and double click it to add the Click event handler:

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

    private void button1_Click(object sender, EventArgs e)
    {
        Bitmap b = new Bitmap(Width, Height);
        DrawToBitmap(b, new Rectangle(0, 0, Width, Height));
        b.Save("Test.bmp");
    }
}
