You have to compare against the strings in the NameTable e.g.

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml( @"<?xml version=""1.0"" encoding=""UTF-8""?>
<myConfig:myCon fig xmlns:myConfig= ""http://mycomp/myConfig.xsd"">
<myConfig:title >My Title</myConfig:title>
</myConfig:myConf ig>");

XmlNamespaceMan ager namespaceManage r = new
XmlNamespaceMan ager(xmlDoc.Nam eTable);
namespaceManage r.AddNamespace( "myConfig",
"http://mycomp/myConfig.xsd");
string prefix =
namespaceManage r.LookupPrefix( xmlDoc.NameTabl e.Get("http://mycomp/myConfig.xsd")) ;
Console.WriteLi ne("Prefix is: " + prefix);
