string address = "https://api-3t.sandbox.paypal.com/nvp?USER=user&COUNTRYCODE=US&ZIP=95131&STATE=CA&CITY=San Jose&FIRSTNAME=John&LASTNAME=Smith&STREET=1asfasdfSt&CVV2=123&ACCT=4683075410516684&IPADDRESS=192.168.0.62&PWD=1357635822&EXPDATE=042011&VERSION=58.0&SIGNATURE=signature&METHOD=DoDirectPayment&CREDITCARDTYPE=Visa&AMT=10.00&PAYMENTACTION=Sale&RETURNURL=http://returnurl&CANCELURL=http://cancnelurl";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);
HttpWebResponse response2 = (HttpWebResponse)request.GetResponse();
Stream stream = response2.GetResponseStream();
StreamReader rdr = new StreamReader(stream);
string req = rdr.ReadToEnd();
But the req contains the failure message. 但是req包含失败消息。 I don't know what credentials i am missing. 我不知道我缺少什么凭证。 Any help is appreciated. 任何帮助表示赞赏。

The error message states that its the expiry date thats the problem. 该错误消息指出其有效期限就是问题所在。
You are passing EXPDATE=042011 which looks to me like a date in the past. 您正在传递EXPDATE = 042011，在我看来，这就像过去的日期。
Edit: 编辑：
10500 Invalid Configuration This transaction cannot be processed due to an invalid merchant configuration. 10500无效的配置由于无效的商家配置，无法处理此交易。 Occurs when you have not agreed to the billing agreement. 在您尚未同意结算协议时发生。
10501 Invalid Configuration This transaction cannot be processed due to an invalid merchant configuration. 10501无效的配置由于无效的商家配置，无法处理此交易。
Occurs when the billing agreement is disabled or inactive. 在记帐协议被禁用或无效时发生。

As it was already mentioned, the error that you are getting is because pro is not enabled on the account you are using the credentials for. 如前所述，您收到的错误是因为您使用凭据的帐户未启用pro。 Express Checkout does not require any special billing agreement, this is why your Express Checkout calls were working. Express Checkout不需要任何特殊的计费协议，这就是为什么您的Express Checkout通话正常的原因。
I have enabled to pro service on your test sandbox account, and you should be able to test with it now. 我已经为您的测试沙箱帐户启用了Pro服务，您现在应该可以对其进行测试。
