c#的内存不足问题，经典问题了吧，就是不会解决啊！帮忙

[vcfansli]

代码如下：
public void AddShuiYinPic(string path, string Path_syp, string Path_sypf)
{
path = path.Replace(@"\\",@"\");
path = path.Replace("/",@"\");

System.Drawing.Image image = System.Drawing.Image.FromFile(path);
//string changedImage = string.Empty;
if (IsPixelFormatIndexed(image.PixelFormat))
{
MemoryStream ms = new MemoryStream();
Bitmap bmp = new Bitmap(image);//生成位图
bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
image.Dispose();
image = System.Drawing.Image.FromStream(ms, true);
bmp.Dispose();
ms.Close();
ms.Dispose();
}

//System.Drawing.Image image = System.Drawing.Image.FromFile(path);
System.Drawing.Image copyImage = System.Drawing.Image.FromFile(Path_sypf);
System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(image);
g.DrawImage(copyImage, new System.Drawing.Rectangle(image.Width - copyImage.Width, 0, copyImage.Width, copyImage.Height), 0, 0, copyImage.Width, copyImage.Height, System.Drawing.GraphicsUnit.Pixel);
g.Dispose();

image.Save(Path_syp);
image.Dispose();
copyImage.Dispose();
}

会出现内存不足的提示，但是代码没啥问题啊，帮助看看吧。谢谢了高手们。

注意清空上次驻留的图.

把上次保存的图临时文件删除，占用空间导致。
