Invalid XMlRoot Element

My output of xml should be like this

<ns1:customerApplication
     soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
     xmlns:ns1="urn:">

I added xmlRoot

[XmlRoot("ns:customerApplication ")]
public class customerApplication     
{
}

But i am getting like this

  <ns_x003A_CustomerApplication xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    </ns_x003A__CustomerApplication>

How to change ns_x0开发者_运维知识库03A_CustomerApplication to ns:CustomerApplication

please help

thanks supriya

You specifying element name only and as result it had to escape ":" to something that is accepted as element name - x003A_ (hex-encoded code of ":").

You need to specify namespace and node name as shown in http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlrootattribute.aspx.

[XmlRoot(Namespace = "www.contoso.com", 
  ElementName = "MyGroupName")]
 public class Group ...
