You're trying to unit test a service reference which is not a valid unit test.  The unit test should test the logic that handles the service response by using a mock object.  Or test the WCF service implementation.

ok before doing unit test I want to read inner element in xml  "netoutcome==block" then I can do the unit test.I wrote below code  but not able read the values

public void ValidateTestFail()

{

var o = new Program();

var n = o.NewOrderRequest();

//using (var reader = XmlReader.Create(new StringReader(n.ToString())))

//{

// while (reader.Read())

// {

// if (reader.IsStartElement())

// {

// var attr = reader["OPIForEW"];

// if (attr == "OPIForEW" )

// {

// if (reader.ReadToDescendant("_NetOutcome"))

// {

// reader.Read();

// result = reader.Value;

// break;

// }

// }

// //if (attr == "_NetOutcome" && attr == "Block")

// //{

// // if (reader.ReadToDescendant("_NetOutcome"))

// // {

// // reader.Read();

// // result = reader.Value;

// // break;

// // }

// //}

// }

// }

//}

var reader = XmlReader.Create(new StringReader(n.ToString()));

while (reader.Read())

{

}

//Assert.AreEqual(n, s);

}

You are showing what looks like a service reference.  Generally the service reference deserializes XML (SOAP) and returns a strong type.  The mock should be a type not XML.  As written you are testing XML deserialization and/or XPath which has already been tested by Microsoft.
