xml的读取（曾删改）

获取XML 得到 需要查询的字段名

    private string GetXml(string TableName) {
        try
        {
            string TbName = TableName.Split('_')[TableName.Split('_').Length - 1].ToString();
            string path = System.AppDomain.CurrentDomain.BaseDirectory;
            XElement xe = XElement.Load(@"" + path + "\Configs\PageConfig\Query\PagePermission.xml");//xml文件所在位置
            IEnumerable<XElement> elements = from ele in xe.Elements("PagePermission") select ele;//linq 方式查询xml内容
            IEnumerable<XElement> Pages = from ele in elements.Elements("Pages") select ele;//拿到PagePermission 下的子节点  也可以根据.Elements(); 拿到子节点
            IEnumerable<XElement> Page = from ele in Pages.Elements("Page") where (string)ele.Attribute("PageAuthCode") == TbName select ele;//筛选所需的Page
            string Code = "";
            foreach (var p in Page)
            {
                IEnumerable<XElement> MultiFuzzyQuerys = from ele in p.Elements("MultiFuzzyQuerys") select ele;//linq 方式查询xml内容
                MultiFuzzyQuerys = MultiFuzzyQuerys.Elements();
                var MultiFuzzyQuery = MultiFuzzyQuerys.Elements();
                int i = 1;
                foreach (var m in MultiFuzzyQuery)
                {
                    if (i == MultiFuzzyQuery.Count())
                    {
                        Code += (string)m.Attribute("Code");
                    }
                    else
                    {
                        Code += (string)m.Attribute("Code") + "-";
                    }
                    i++;
                }
            }
            return Code;
        }
        catch (Exception)
        {
            return "";
            //throw;
        }
        
    }
