问题描述
嗨
我正在从webservice读取xml数据并将其加载到datatable中时出现错误
为不同的映射定义了列名id类型
< 国家 id = 350 标识符 = 黑山 >
< span class =code-keyword>< id > 350 < / id >
< c lient id = 0 entity-name = ADClient 标识符 = 系统 / >
< 组织 id = 0 entity-name = 组织 标识符 = * / >
< 有效 > true < < span class =code-leadattribute> / active >
< creationDate transient = true > 2013-01-30T07：35 ：18.545Z < / creationDate >
< createdBy transient = true id = 0 entity-name = ADUser 标识符 = 系统 / >
< 已更新 transient = true > 2013-01-30T 07：35：18.545Z < / updated >
< updatedBy transient = true id = 0 entity-name = ADUser identifier = 系统 / >
< name > Montenegro < / name >
< description > 黑山< / description >
< iSOCountryCode <跨度类= 代码关键字 >> ME <跨度类= 代码关键字 >< <跨度类= 代码leadattribute > / iSOCountryCode >
< hasRegions > false < / hasRegions &g t;
< regionName > 州< / regionName >
< phoneNoFormat xsi：nil = true / >
< ; addressPrintFormat > @ C @，@ P @ < / addressPrintFormat >
< postalCodeFormat xsi：nil = true / >
< additionalPostalCode > false < / additionalPostalCode >
< additionalPostalFormat xsi：nil = true / >
< 默认 > false < / default >
< language xsi：nil = true / >
< currency id = 102 entity-name = 货币 identifier = EUR / >
< iBANLength > 22 < / iBANLength >
< iBANCode > ME < / iBANCode >
< decimalseparator xsi：nil < span class =code-keyword> = true / >
< groupingseparator xsi：nil = true / >
< numericmask xsi：nil = true / >
< dateformat xsi：nil = true / >
< datetimeformat xsi：nil = true / >
< countryTrlList / >
< regionList / >
< / Country >
由于id同时使用作为属性和元素，这是名称ID之间的冲突..如何重命名或解决它....我不能改变webservice因为我没有访问它
用于加载数据表的代码是
Da taTable dt = new DataTable（）;
using（var client = new WebClient {Credentials = new NetworkCredential（ 用户名， 密码）}）
{
string result = client.DownloadString（uri）;
XmlTextReader reader = new XmlTextReader（ new StringReader（result））;
dt.ReadXml（读者）;
return dsGetValues;
}
谢谢

解决方案
试试这个< br $>
static void Main（string [] args）
{
DataSet ds = new DataSet（）;
ds.EnforceConstraints = false;
ds.ReadXmlSchema（XMLSchema1.xsd）;
XmlTextReader reader = new XmlTextReader（XMLFile1.xml）;
ds.ReadXml（读者）;
}
我已将xml保存在名为XMLFile1.xml的文件中，并创建名为XMLSchema1.xsd的XSD 。以下是XSD的内容。希望这可以解决你的问题。

Hi
Im reading a xml data from webservice and while loading it into datatable im getting an error
" Column name id is defined for different mapping types"
<Country id="350" identifier="Montenegro">
<id>350</id>
<client id="0" entity-name="ADClient" identifier="System"/>
<organization id="0" entity-name="Organization" identifier="*"/>
<active>true</active>
<creationDate transient="true">2013-01-30T07:35:18.545Z</creationDate>
<createdBy transient="true" id="0" entity-name="ADUser" identifier="System"/>
<updated transient="true">2013-01-30T07:35:18.545Z</updated>
<updatedBy transient="true" id="0" entity-name="ADUser" identifier="System"/>
<name>Montenegro</name>
<description>Montenegro</description>
<iSOCountryCode>ME</iSOCountryCode>
<hasRegions>false</hasRegions>
<regionName>State</regionName>
<phoneNoFormat xsi:nil="true"/>
<addressPrintFormat>@C@, @P@</addressPrintFormat>
<postalCodeFormat xsi:nil="true"/>
<additionalPostalCode>false</additionalPostalCode>
<additionalPostalFormat xsi:nil="true"/>
<default>false</default>
<language xsi:nil="true"/>
<currency id="102" entity-name="Currency" identifier="EUR"/>
<iBANLength>22</iBANLength>
<iBANCode>ME</iBANCode>
<decimalseparator xsi:nil="true"/>
<groupingseparator xsi:nil="true"/>
<numericmask xsi:nil="true"/>
<dateformat xsi:nil="true"/>
<datetimeformat xsi:nil="true"/>
<countryTrlList/>
<regionList/>
</Country>
Since id is used both as attribute and element,ther is a conflict between the name id.. How can i rename it or resolve it ....i cannot the change the webservice since i dont ve access to it
the code m using to load the datatable is
DataTable dt = new DataTable();
using (var client = new WebClient { Credentials =new NetworkCredential("Username","Password") })
{
string result = client.DownloadString(uri);
XmlTextReader reader = new XmlTextReader(new StringReader(result));
dt.ReadXml(reader);
return dsGetValues;
}
Thanks

解决方案
Try this
static void Main(string[] args) { DataSet ds = new DataSet(); ds.EnforceConstraints = false; ds.ReadXmlSchema("XMLSchema1.xsd"); XmlTextReader reader = new XmlTextReader("XMLFile1.xml"); ds.ReadXml(reader); }
I have saved your xml in file named "XMLFile1.xml" and created XSD named "XMLSchema1.xsd". Below is the content of XSD. Hoping this should solve your problem.
