查詢XML [SAML 2.0響應]

下面的xml讓我很困難。我需要用c＃從XML中檢索以下內容，可以請幫忙嗎？還有一種更好的閱讀/解析c＃中的SAML 2.0響應的方式？查詢XML [SAML 2.0響應]

狀態碼從<samlp:StatusCode value="urn:oasis:names:tc:SAML:2.0:status:**Success**"/>
FIRSTNAME值
LASTNAME值
MAIL值
發行人從<saml:Issuer>**sso.localhost.dev**</saml:Issuer>
觀衆從<saml:Audience>**Application-Test**</saml:Audience>

XML

如果你只是想解析XML，你可以加載到一個XElement。

您還可以使用Kentor.AuthServices包的Saml2Response類來解析和驗證響應。
