这个是存到本地的方法。怎么把它改成存到服务器

protected void SaveFile()
{
try
{
FileStream newfile = (FileStream)saveFileDialog.OpenFile();

Point p = new Point(0,0);
int width;
int heigh;
width = Drawing.Width;
heigh = Drawing.Height;
Rectangle r= new Rectangle(p,new Size(width,heigh));
Image i = new Bitmap(width, heigh);
Graphics g = Graphics.FromImage(i);
g.FillRectangle(new SolidBrush(Color.White),r);
if(eraser == true)
notchangeList.DrawList(g);
drawingList.DrawList(g);
newImage = i;

if(fileName != "")
{
switch(saveFileDialog.FilterIndex)
{
case 1:
newImage.Save(newfile,System.Drawing.Imaging.ImageFormat.Jpeg);
break;
case 2:
newImage.Save(newfile,System.Drawing.Imaging.ImageFormat.Bmp);
break;
case 3:
newImage.Save(newfile,System.Drawing.Imaging.ImageFormat.Gif);
break;
default:
newImage.Save(newfile,System.Drawing.Imaging.ImageFormat.Bmp);
break;
}
}
newfile.Close();
}
catch(IOException err)
{
MessageBox.Show(err.Message,"myPGS",MessageBoxButtons.OK,MessageBoxIcon.Exclamation);
}
}

newImage.Save 有重载列表，可以把图片保存成流，再将流保存到webservice即可。

能稍微详细点吗
