如何创建图像并设置其颜色?

How do I create an image and set its color?

推荐答案

我会提供与您要求的一样多的答案.

C#创建图像 [ ^ ]
C#图片颜色 [ ^ ]

I''ll put in as much answering as you did asking.

C# create image[^]
C# image color[^]

这是一种简单但效率低下的方法:

Here''s an easy but rather inefficient approach:

Bitmap bitmap = new Bitmap(100, 100);
for (int i = 0; i < 100; i++)
{
    for (int j = 0; j < 100; j++)
    {
        bitmap.SetPixel(i, j, Color.Blue);
    }
}

public static Bitmap CreateBitmap(int width, int height, Color color)
{
    Bitmap b = new Bitmap(width, -height);
    using (Graphics g = Graphics.FromImage(b))
    {
        g.Clear(color);
    }
    return b;
}
