C# ype=true，命名空间=”http://cpu1147/AB_TestWebApp/")] 公共部分类AddTwoStrParameter { 私有字符串数据类型字段； 私有字符串名称字段； 私有字符串值字段； /// 公共字符串数据类型 { 得到 { 返回this.dataTypeField； } 设置 { this.dataTypeField=值； } } /// 公共字符串名 { 得到 { 返回此.nameField； } 设置 { this.nameField=值； } } /// 公共字符串值 { 得到 { 返回此.valueField； } 设置 { this.valueField=值； } } } } }

我现在的问题是XML现在的格式不好，请参见以下示例：

<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><AddTwoStrResponse xmlns="http://cpu1147/AB_TestWebApp/"><AddTwoStrResult>&lt;Parameter&gt;
  &lt;DataType&gt;String&lt;/DataType&gt;
  &lt;Name&gt;WebResponse&lt;/Name&gt;
  &lt;Value&gt;HalloChristian&lt;/Value&gt;
&lt;/Parameter&gt;</AddTwoStrResult></AddTwoStrResponse></soap:Body></soap:Envelope>

参数

我需要回报的是：

我多次尝试反序列化，但总是收到错误消息“XML中的字符错误”

您说您没有得到任何值……您遇到了什么错误/问题？字符串1和字符串2本身就是上述XML中的值。能否指定要查找的标记值？
