public string GetProjectRootPath()

    string BaseDirectoryPath = AppDomain.CurrentDomain.BaseDirectory; // F:\WAF Projects\mjl\code\HomeDecorationPSD\HomeDecorationPSD\bin\Debug\
    // 向上回退三级，才能到项目的根目录
    rootPath = BaseDirectoryPath.Substring(0, BaseDirectoryPath.LastIndexOf("\\")); // 第一个\是转义符，所以要写两个
    rootPath = rootPath.Substring(0, rootPath.LastIndexOf("\\"));
    rootPath = rootPath.Substring(0, rootPath.LastIndexOf("\\")); // F:\WAF Projects\mjl\code\HomeDecorationPSD\HomeDecorationPSD\
    return rootPath;
