C#Bitmap占用资源不释放解决方案.doc

2、决Bitmap不释放资源问题，先不同的名称保存图片，缩放完后把临时文件删除stringtempPath=strPath.Replace(".","_temp.");intoldWidth=bmOld.Width;intoldHeight=bmOld.Height;intnewHeight=(int)((double)newWidth/oldWidth*oldHeight);if(oldWidth

3、bmOld,newWidth,newHeight);//保存缩放后的图片bmNew.Save(tempPath);bmOld.Dispose();bmNew.Dispose();//获取图片Encoder信息ImageCodecInfo[]codecs=ImageCodecInfo.GetImageEncoders();ImageCodecInfoici=null;foreach(ImageCodecInfocodecincodecs){if(codec.MimeType=="image/jpeg")ici=codec;}EncoderParameterse

4、p=newEncoderParameters();//给定的参数qualityep.Param[0]=newEncoderParameter(Encoder.Quality,(long)quality);//从临时文件中读取图片Imageimg=Image.FromFile(tempPath);//以给定的参数保存图片img.Save(strPath,ici,ep);img.Dispose();//最后删除临时图片File.Delete(tempPath);}catch(Exceptionex){newDatabase().SysLog(ex,"PicSto

5、re.ResizePic(""+strPath+"","+newWidth+",""+quality+"",)");}finally{bmOld=null;bmNew=null;}}
