c# 读取xsd文件(Schema文件)
C# 如何读取xsd文件？就是Schema文件，此文件内容大概如下：
<?xml version="1.0" encoding="UTF-8"?>

<xs:schema xmlns:snp="http://www.sinopec.com/cas/2010-12-31" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:link="http://www.xbrl.org/2003/linkbase" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xbrli="http://www.xbrl.org/2003/instance" xmlns:xbrldt="http://xbrl.org/2005/xbrldt" xmlns:nonnum="http://www.xbrl.org/dtr/type/non-numeric" xmlns:num="http://www.xbrl.org/dtr/type/numeric" targetNamespace="http://www.sinopec.com/cas/2010-12-31" elementFormDefault="qualified">

</xs:schema>


------解决方案--------------------

C# code

XmlDocument doc = new XmlDocument();
            doc.Load(""); 
            XmlNodeList nodelist = doc.SelectNodes("xpath");
            foreach (XmlNode item in nodelist)
            {
                //item.InnerText
                //item.Attributes["name"].InnerText
            }

------解决方案--------------------
还可以使用Linq to XML来读取XML
C# code
 XDocument docc = XDocument.Load("uri");

------解决方案--------------------
doc.Load("这里要写上你的文件路径");
