有点模糊，我会尝试猜测:

将数据读入缓冲区并创建MemoryStream

A bit vague, I''ll attempt a guess:

Read the data into a buffer and create a MemoryStream

byte[] buffer; // read data to this. omitted.
MemoryStream stream = new MemoryStream(buffer);

从流创建位图

Create a Bitmap from the stream

Bitmap bitmap = new Bitmap(stream);

在窗体的Paint事件处理程序中，绘制图像如下:

In the form''s Paint event handler, draw the image thus:

private void Form1_Paint(object sender, PaintEventArgs e)
{
    e.Graphics.DrawImage(bitmap, x, y);
}

x和y是绘制图像的位置的坐标.
(在MSDN中查找每种方法以获取详细信息)

x and y are the coordinates of the place where you draw the image.
(look up each method in MSDN for details)
