PictureBox1.Image.Save() using C#

Yes, Application.StartUpPath will go to debug folder only. usually we don't use the solution folder in runtime environment because of security issues.

if the XML files serves configuration information, you better include a configuration file.

if you are using xml file for some other purpose you have to give the location of the file. even though you are storing it in the solution folder (Project Name -> add new item -> XML file )  you need to give the full path.

 The main problem is

I created an xml in my application by MyWindowsApplication -> Add New Item -> XML File  and created data in that. ok it's fine. But when ever iam trying to  Load(XmlDocument.Laod)  that XML using Application.StratUpPath it is going to ....\bin\Debug\... instead of getting MyXML which i have creaed recently. and it showing file not found error....

Am i clear in explaining  my dought.. if not again i will expalin it clearly ..

I think u can't access ur project folder(where forms, forms.cs are stored) during runtime or after deployment.
It is accessible only during compile time.

SO you can access only the debug folder during runtime.

if the picture is loaded in the picture box and you want to store it in solution folder,  hope the following couple of lines can help you

string filename = Application.StartupPath + "\\myImage.jpg";
