Hey!

This is one way to do it. I have used this when i needed to make some changes to the image if you just want to copy the image you could use StreamWriter to save the image insted.

Stream buffer;
StreamReader srImage = new StreamReader(st rPathNFileName) ;
buffer = srImage.BaseStr eam;
Bitmap bmImage = new Bitmap(buffer);
bmImage.Save(st rNewPathNFileNa me)


Good luck!

i got a error " a generic error occured in GDI+".

   myText.Text = fileDialog.FileName;
                    strPathNFileName=fileDialog.FileName;
                    Stream buffer;
                    StreamReader srImage = new StreamReader(strPathNFileName);
                    buffer = srImage.BaseStream;
                    Bitmap bmImage = new Bitmap(buffer);
                    StreamWriter srSettings = new StreamWriter(AppDomain.CurrentDomain.BaseDirectory + "..\\..\\Images\\");
                    srSettings.Write(bmImage);

Try not to use the StreamWriter insted use the code that i pasted, the method Save() in the Bitmap class

thank you so much. it is working, but it is saving as system.drawing. bitmap

myText.Text = fileDialog.FileName;
                    strPathNFileName=fileDialog.FileName;
                    Stream buffer;
                    StreamReader srImage = new StreamReader(strPathNFileName);
                    buffer = srImage.BaseStream;
                    Bitmap bmImage = new Bitmap(buffer);
                    bmImage.Save(AppDomain.CurrentDomain.BaseDirectory + "..\\..\\Images\\"+bmImage);

Since you are using bmImage as file name and concat it to your path you will force it to call it´s ToString() method wich outputs what your file will be named.

this is your code:

bmImage.Save(AppDomain.CurrentDomain.BaseDirectory   + "..\\..\\Images\\"+bmImage);

use this insted:

string strFileName= fileDialog.FileName.Substring(fileDialog.FileName.LastIndexOf("\\") + 1);
bmImage.Save(AppDomain.CurrentDomain.BaseDirectory   + "..\\..\\Images\\"+strFileName);

this will give your file same name as it had before....

Hope this helps

Why not simply using the File Class

File.Copy(oldPath, newPath);

just 1 line of code that does it all: copy a file

[krille]

So true. Go with that since you not gonna use any features of the Bitmap class anyway

Thank you so much Krille and Wimpos, Both your Codes are working Fine.
