如何在文件夹中保存图像. [英] How to save image in folder.

问题描述

我正在将bytearray []转换为System.drawing.image，这工作正常.但是如何将这个图像保存到本地目录中.

如果我给_objImage.Save(path，_objImage.RawFormat);这会导致错误.

"GDI +中的错误"
给我一个解决办法.



对不起，我听不懂.
这是我的代码，用于将base64代码转换为图像.

hi ,
I am converting bytearray[] to System.drawing.image this is working fine. But how can i save this image into local directory.

if I give _objImage.Save(path,_objImage.RawFormat); this give an error.

"Error in GDI+"
Give me a solution.



Sorry I can''t understand.
This is my code to convert base64 code into image.

public static Image Base64ToImage(string base64String)
{
 
byte[] imageBytes = Convert.FromBase64String(base64String);
Image image;
using (MemoryStream inStream = new MemoryStream())
{
inStream.Write(imageBytes, 0, imageBytes.Length);
 
image = Bitmap.FromStream(inStream);
// image.Save(inStream, System.Drawing.Imaging.ImageFormat.Png);
image.Save(inStream, image.RawFormat);
}

return image;
}

现在我想将此图像保存到本地目录中，我该怎么做.

如果我使用

Now i want save this image into local directory how can i do this.

if i use

Image _ObjImage = Base64ToImage(Img);
DirectoryInfo dir = new DirectoryInfo(PATH + @"EndUsersUI\UploadedPic\" + id +"\\");
_ObjImage.Save(dir + smallpicname, _ObjImage.RawFormat);

这给了我一个错误.

This is giving me an error.

推荐答案

现在服务器中已有JPG文件.如果要保存在客户端计算机中，则必须进行传输.这是代码:-

Now you have JPG file in server. If you want to save in client machine then you have to transmit that. Here is code :-

Response.ContentType = "image/jpeg";
        Response.AppendHeader("Content-Disposition", "attachment; filename=Image.jpg");
        Response.TransmitFile(Server.MapPath("Image.jpg"));
        Response.End();

最后我解决了.
答案是将ByteArray []转换为Image中没有的Bitmap之后，您可以轻松地将图像存储到任何文件夹中，或者可以通过Drawing类的resize方法进行裁剪.

Finally i have solved.
and the answer is Convert ByteArray[] to Bitmap not in Image after that u can easily store your image into any folder or u can crop this through resize method of Drawing class.
