如何从c#中包含XML的字符串中读取数据？

Question

我已经在这个问题上找到了很多答案,但是他们都试图将字符串首先转换为文件,然后尝试使用它来解析它 XmlDocument doc = new XmlDocument();

我是新手c#.我的字符串的格式是:

<a header = '0'> < row dc = '123' al = '45' msg = '1-st line'/> < row dc = '678' al = '8' msg = 'second-line'/> </a>

我正在尝试编写伪代码来解析它:

IF <a header> == 0
Then read from the second line to last line i.e. dc = 678 , al = 8, msg = second-line
ELSE read from the first line to last line i.e.  
  dc = 123 , al = 45, msg = 1-st line
 dc = 678 , al = 8, msg = second-line

在此之后我必须插入数据库.在应用上述条件时,什么是适当的解决方案呢？

您不必保存到文件来解析XML.

var xml = "<a header='0'> <row dc='123' al='45' msg='1-st line'/> <row dc='678' al='8' msg='second-line'/> </a>";
var doc = XElement.Parse(xml);
var list = from x in doc.Descendants("row")
            select new 
            {
                dc = (int)x.Attribute("dc"),
                al = (int)x.Attribute("al"),
                msg = (string)x.Attribute("msg")
            };

这个简单的示例将为您提供一个匿名对象列表,然后您可以轻松地将其插入到数据库中.
