If you're using .NET Core or .NET 5+, there's a helpful ToXmlString() method on the RSA class.

var privateKey = await File.ReadAllTextAsync("mypemfile.pem");
var rsa = RSA.Create();
rsa.ImportFromPem(privateKey.ToCharArray());
var d = new XmlDocument();
d.LoadXml(rsa.ToXmlString(true));
d.Save("mypemfile.xml");
