xml获取配置DataTable

在CSDN写博客时，经常遇到需要绑定数据源的时候，可是自己从数据库获取数据的函数都是已经封装好了的，这样别人复制你的代码，要想看到结果，还得修改修改，很是麻烦，博客实例，数据源简单点就好，这样别人写你写的实例时，不用新建数据库，或者不用自己整个获取数据源的函数，效率低，我要的是快速看运行结果，实例是否是正确，能够把你的代码复制下来，F5运行就可以直接看到效果。所以我就写了一个通过XML获取配置DataTable.这样以后自己写博客，需要绑定数据源的时候，不同的数据源，修改一下XML就可以了。

下面的实例的所有数据源都是通过xml获取的

一，效果图

核心代码：

public DataTable getDTXML(string xmlname)
        {
            DataTable result = new DataTable();
            string fileName = HttpContext.Current.Request.PhysicalApplicationPath + "\\Xml\\" + xmlname + ".xml";//xml的物理路径
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(fileName);
            XmlNodeList xWitsTablesList = xmlDoc.SelectNodes("/config");
            foreach (XmlNode xOracleNode in xWitsTablesList)
            {
                foreach (XmlNode node2 in xOracleNode.ChildNodes)
                {
                    if (node2.Name == "Header")
                    {
                        //   //绑定表头
                        foreach (XmlNode node3 in node2.Attributes)
                        {
                            result.Columns.Add(node3.Value);
                        }
                    }
                    else
                    {
                        //数据行
                        int i = 0;//列标志
                        DataRow dr = result.NewRow();
                        foreach (XmlNode node4 in node2.Attributes)
                        {
                            dr[i] = node4.Value.ToString();
                            i++;
                        }
                        result.Rows.Add(dr);
                    }

                }
            }
            return result;
        }

xml示例

<?xml version="1.0" encoding="utf-8" ?>
<config>
    <Header  col1="班级编号" col2="班级名称" col3="年级" col4="学校" col5="男生" col6="女生"  col7="人数"/>
    <row     col1="11" col2="一（一）班" col3="初一" col4="三峡高级中学" col5="20" col6="30"  col7="50"/>
    <row     col1="12" col2="一（二）班" col3="初一" col4="三峡高级中学" col5="18" col6="12"  col7="30"/>
    <row     col1="13" col2="一（三）班" col3="初一" col4="三峡高级中学" col5="16" col6="26"  col7="42"/>
    <row     col1="14" col2="一（四）班" col3="初一" col4="三峡高级中学" col5="23" col6="17"  col7="40"/>
</config>

二，下面贴出源码：

1）表头配置.xml文件：

<?xml version="1.0" encoding="utf-8" ?>
<config>
    <Header  col1="班级编号" col2="班级名称" col3="年级" col4="学校" col5="男生" col6="女生"  col7="人数"/>
    <row     col1="11" col2="一（一）班" col3="初一" col4="三峡高级中学" col5="20" col6="30"  col7="50"/>
    <row     col1="12" col2="一（二）班" col3="初一" col4="三峡高级中学" col5="18" col6="12"  col7="30"/>
    <row     col1="13" col2="一（三）班" col3="初一" col4="三峡高级中学" col5="16" col6="26"  col7="42"/>
    <row     col1="14" col2="一（四）班" col3="初一" col4="三峡高级中学" col5="23" col6="17"  col7="40"/>
</config>
