.Net framework using reflection to invoke a private member

• Example from the .Net framework of using reflection to invoke a private member from another class

in : System.Data, Version=2.0.0.0

in System.Data.SqlClient.SqlCachedBuffer.ToXmlReader() : XmlReader

internal XmlReader ToXmlReader() {

     XmlReader reader1;
     SqlCachedStream stream1 = new SqlCachedStream(this);
     XmlReaderSettings settings1 = new XmlReaderSettings();
     settings1.ConformanceLevel = ConformanceLevel.Fragment;
     MethodInfo info1 = typeof(XmlReader).GetMethod("CreateSqlReader", BindingFlags.NonPublic | BindingFlags.Static);
     object[] objArray1 = new object[3];
     objArray1[0] = stream1;
     objArray1[1] = settings1;
     object[] objArray2 = objArray1;
     new ReflectionPermission(ReflectionPermissionFlag.MemberAccess).Assert();
     try
     {
           reader1 = (XmlReader) info1.Invoke(null, objArray2);
     }
     finally
     {
           CodeAccessPermission.RevertAssert();
     }
     return reader1;

}

to see other similar example of this use the Analyzer on System.Security.Permissions.ReflectionPermissionFlag
