XML

I am trying to deserialize the XML data but due to & it is getting exception but i need to insert xml with the same data.

Below is my sample xml data
string xml=@"
<customer>
<companyname>
Testing & Testing Pvtltd

<customer>";

I am using the below code

public static T Deserialize<T>(string xml)
    {
XmlSerializer ser =new XmlSerializer(typeof(T));
        T obj;
        using (MemoryStream memStream = new MemoryStream(new UTF8Encoding()).GetBytes(xml)))
        {
            
            obj = (T)ser.Deserialize(memStream);
        }
        return obj;
    }

What I have tried:

string xml=@"
<customer>
 <CompanyName>
    Testing & Testing Pvtltd
 </CompanyName>
<customer>";

I am using the below code



<pre>public static T Deserialize<T>(string xml)
    {
XmlSerializer ser =new XmlSerializer(typeof(T));
        T obj;
        using (MemoryStream memStream = new MemoryStream(new UTF8Encoding()).GetBytes(xml)))
        {
            
            obj = (T)ser.Deserialize(memStream);
        }
        return obj;
    }
