System.InvalidOperationException : 不应有 。

xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<Response version="2">
  <datacash_reference>4700203048783633</datacash_reference>
  <information>Failed to identify the card scheme of the supplied card number</information>
  <merchantreference>1000001</merchantreference>
  <mode>TEST</mode>
  <reason>Invalid card type</reason>
  <status>21</status>
  <time>1382512427</time>
</Response>

原来的Entity如下：

    [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.1")]
    [Serializable()]
    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [XmlType(AnonymousType = true)]
    [XmlRoot(Namespace = "", IsNullable = false)]

解决方案需要增加ElementName = "Response"，如下：

    [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.1")]
    [Serializable()]
    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    [XmlType(AnonymousType = true)]
    [XmlRoot(Namespace = "", IsNullable = false, ElementName = "Response")]

Done!
