c# – 无法将字符串转换为XML

概述我将 XML作为字符串传递给方法,并再次将其转换为XML来完成我的工作. 它的工作正常,但是当有特殊字符时,如&或=它给出了一个错误. 我的XML字符串： <SuggestedReadings> <Suggestion Text="Customer Centricity" Link="http://wdp.wharton.upenn.edu/book/customer-centricity/ 我将 XML作为字符串传递给方法,并再次将其转换为XML来完成我的工作.

它的工作正常,但是当有特殊字符时,如&或=它给出了一个错误.

我的XML字符串：

<SuggestedReadings>   <Suggestion Text="Customer Centricity" link="http://wdp.wharton.upenn.edu/book/customer-centricity/?utm_source=Coursera&utm_medium=Web&utm_campaign=custcent" SuggBy="Pete Fader�s" />   <Suggestion Text="Global Brand Power" link="http://wdp.wharton.upenn.edu/books/global-brand-power/?utm_source=Coursera&utm_medium=Web&utm_campaign=glbrpower" SuggBy="barbara Kahn�s" /></SuggestedReadings>

我的代码是：

public class saveData(string strXml){      Xmldocument xmlDoc = new Xmldocument();      xmlDoc.LoadXml(CD.SRList);// here its giving error}

错误：

‘=’ is an unexpected token. The expected token is ‘;’. line 1,position 150.

完整错误是：

解决方法 您的文档缺少XML标头,这是必需的.此外,你没有正确地逃避&字符.

尝试在XML文档之上添加它：

<?xml version="1.0" enCoding="UTF-8"?>

并且还替换&与& amp ;. (见list of characters to escape)
