如何从XML或文本文件读取特定数据？

Question

I want to store user data in a XML or text file. I know how to write data into a file, the problem I have is reading that data and getting what I want out of it.

I want to store a MySQL connection string with my own custom data. For example...

 "Name=Localhost;CoreVerr=5.x;Server=127.0.0.1;Port=3306;Uid=root;Password=root;Database=accounts;"

Note that the custom data is "Name" and "CoreVerr" as these are not found in a normal MySQL connection string.

Now I want to read data from "Name" and "CoreVerr". So the output would then be, 'Localhost', '5.x'. How could I do this? Thanks.

Answer 1

It sounds like you are looking for application and user settings .

Settings allow you to specify configuration values in setting files and provide easy access.

You can use the XmlDocument class to do this in C#. https://msdn.microsoft.com/en-us/library/system.xml.xmldocument%28v=vs.110%29.aspx

This allows you to target specific nodes and attributes within your XML document once you have loaded it and extract the information required.
