As for this issue, I suggest you could check the object class. When you set the property, you need to check whether it is null. You could refer to the following code:
[XmlRoot("root")]
public class Sample1Xml
{
[XmlElement("node")]
public NodeType Node { get; set; }
#region Nested type: NodeType
public class NodeType
{
[XmlAttribute("attr1")]
public string Attr1 { get; set; }
[XmlAttribute("attr2")]
public string Attr2 { get; set; }
[XmlIgnore]
public string Content { get; set; }
[XmlText]
public XmlNode[] CDataContent
{
get
{
var dummy = new XmlDocument();
return new XmlNode[] {dummy.CreateCDataSection(Content)};
}
set
{
if (value == null)
{
Content = null;
return;
}
if (value.Length != 1)
{
throw new InvalidOperationException(
String.Format(
"Invalid array length {0}", value.Length));
}
var node0 = value[0];
var cdata = node0 as XmlCDataSection;
if (cdata == null)
{
throw new InvalidOperationException(
String.Format(
"Invalid node type {0}", node0.NodeType));
}
Content = cdata.Data;
}
}
}
#endregion
}

Hi jagadishnpy,
Welcome to asp.net forum.
As for this issue, I suggest you could check the object class. When you set the property, you need to check whether it is null. You could refer to the following code:
[XmlRoot("root")] public class Sample1Xml { [XmlElement("node")] public NodeType Node { get; set; } #region Nested type: NodeType public class NodeType { [XmlAttribute("attr1")] public string Attr1 { get; set; } [XmlAttribute("attr2")] public string Attr2 { get; set; } [XmlIgnore] public string Content { get; set; } [XmlText] public XmlNode[] CDataContent { get { var dummy = new XmlDocument(); return new XmlNode[] {dummy.CreateCDataSection(Content)}; } set { if (value == null) { Content = null; return; } if (value.Length != 1) { throw new InvalidOperationException( String.Format( "Invalid array length {0}", value.Length)); } var node0 = value[0]; var cdata = node0 as XmlCDataSection; if (cdata == null) { throw new InvalidOperationException( String.Format( "Invalid node type {0}", node0.NodeType)); } Content = cdata.Data; } } } #endregion }For more details, please refer to the following links:
