c# - Web API method with parameters not working in MVC4 -

-

मेरे पास निम्न API विधि है: 

  [HttpGet] सार्वजनिक सूची & lt; ListOfUsersModel & gt; GetRegisteredUsers (int courseId) {सूची & lt; अकाउंट कॉरस & gt; GetUsers = नया AdminBL ()। GetAccountIdByCourseId (पाठ्यक्रम आईडी); Var ListOfUsers = नई सूची & lt; ListOfUsersModel & gt; (); विदेशी मुद्रा (गेटयूसर्स में खाताकॉर्स्) {ListOfUsersModel lum = नया ListOfUsersModel (); Lum.user = a.AccountId.ToString (); ListOfUsers.Add (Lum); } लौटें सूचीऑफयूजर; }

यदि मैं इसके बजाय "GetRegisteredUsers ()" विधि को संशोधित करता हूं, तो यह बिल्कुल ठीक काम करता है। हालांकि, अगर मैं एक पैरामीटर निर्दिष्ट करना चाहता हूं मुझे निम्न संदेश मिलता है: नियंत्रक 'तीसरे पक्ष' पर कोई कार्रवाई नहीं मिली जो अनुरोध से मेल खाती है। "}

वैश्विक रूप में, मेरे पास यह है:

<पूर्व> मार्गों। MapHttpRoute (नाम: "DefaultApi", मार्गटैम्प्लेट: "एपीआई / {नियंत्रक} / {action} / {courseId}", डिफ़ॉल्ट: नया {courseId = RouteParameter.Optional});

मुझे नहीं पता कि मैं यहाँ क्या गलत कर रहा हूं, कोई मदद? धन्यवाद

Powerbuilder 12.1 and DataWindow in Design vs Debug and Executable/Runtime -

-
I have a very strange situation with Powerbuilder 12.1. I have two issues that can be related - mainly because this is the exact same data window report. Problem # 1: You can not see the contents of Detavindo any and went nowhere, lost the ability to debug and display content Detavindo at runtime during the debug and runtime. But when you go into the data window in design mode, it prompts for the values ​​of those parameters, the content is only displayed, it is okay. Edit: Solve. This is due to a powerbiller that uses an integer rather than a long variable. The identity identifier in the database exceeds the upper limit of a PowerBuilder 16-bit integer (32767). I updated the logic for longer use, and resolved this problem # 1. ISSUE # 2: When I run the report code using the same data window mentioned in issue # 1 above, in debug mode, to create a new report file, this work Done - only in DEBUG mode Runtime failure - I got an error -1 during the runtime for the exact same...
