== .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;
}
