c# - Saving a file in a specified folder inside my project

Question

I am creating an Xml file and I want to save it in a specified folder inside my project within the solution where I can access it in the Solution Explorer.

How can I specify the path so that a folder is created and the xml file saved inside it?

As it is at the moment it creates the file in the root directory of my project and I cannot view it in Solution Explorer.

 XmlSerializer serializer = new XmlSerializer(typeof(BoxSet));
 TextWriter textWriter = new StreamWriter("../../Box.xml");

Sorry, still a newbie...am I missing something.?

Answer 1

您可以在声明新的 StreamWriter 时指定路径。

TextWriter textWriter = new StreamWriter("../../Box.xml");

这归结为：

• ../ - 上一个目录
• ../ - 上一个目录
• Box.xml 文件在这里

因此，当您希望在根文件夹内的文件夹中创建文件时，您可以使用：

• “../文件夹名称/Box.xml ”

但是，如果您不想依赖当前文件位置，也可以使用：

AppDomain.CurrentDomain.BaseDirectory

这将使：

var path = String.Format("{0}foldername\Box.xml", AppDomain.CurrentDomain.BaseDirectory);
TextWriter textWriter = new StreamWriter(path);

希望这可以帮助。

Answer 2

而不是使用AppDomain.CurrentDomain.BaseDirectory你可以这样做：

    TextWriter textWriter = new StreamWriter("foldername\\Box.xml");

当您不添加任何内容时，将自动假定基本目录。
