XML Encode & Decode

Whenever we use XML in your application, we might be required to encode and decode the data which we are passing in the XML since the data may contain some special charecters like XML tags. The charecters '<', '>', '&' and '"' may have to be replaced. I use these methods to encode and decode XML strings.

public string XMLEncode(string Value)
{
     return Value.Replace ("&", "&amp;").Replace("'", "&apos;").Replace ("\"", "&quot;").Replace ("<", "&lt;").Replace(">", "&gt;");
} 
        
public string XMLDecode(string Value)
{
    return Value.Replace ("&amp;", "&").Replace("&apos;", "'").Replace("&quot;", "\"").Replace ("&lt;", "<").Replace ("&gt;", ">");
}
