How to use

This library can help you easily convert a class to XML file (just property of this class), or read data from XML file. Here are some functions:

/// <summary>
/// Read or create default configure file.
/// If read file not exists, create one by new T object, and this file version will be the param TargetVersion.
/// If read file exists, compare the file version and the param TargetVersion.
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="FilePath">File Path</param>
/// <param name="TargetVersion">Target version</param>
/// <returns>Configure class</returns>
/// <exception cref="Exception"></exception>
public static T ReadConfigFile<T>(string FilePath, string TargetVersion = "1.0");

/// <summary>
/// Save configure file, will replace old file.
/// </summary>
/// <param name="ConfigObj"></param>
/// <param name="FilePath"></param>
/// <param name="FileVersion"></param>
public static void SaveConfigFile(object ConfigObj, string FilePath, string FileVersion);

/// <summary>
/// File version
/// </summary>
public static string? FileVersion { get; set; }
