[liangming2003]

Below is code for creating a work item.

The "\r\n" in the string description is not recognized, so the description text of newly created item is on one line.

How to create a work item with multi-line description with code, thanks.

 public static WorkItem CreateWorkItem(VssConnection connection, string title, string type, string description, string tags)
        {

            string project = "xxx";

            // Construct the object containing field values required for the new work item
            JsonPatchDocument patchDocument = new JsonPatchDocument();

            patchDocument.Add(
                new JsonPatchOperation()
                {
                    Operation = Operation.Add,
                    Path = "/fields/System.Title",
                    Value = title
                }
            );

            patchDocument.Add(
                new JsonPatchOperation()
                {
                    Operation = Operation.Add,
                    Path = "/fields/System.Description",
                    Value = description
                }
            );

            // Get a client        
            WorkItemTrackingHttpClient workItemTrackingClient = connection.GetClient<WorkItemTrackingHttpClient>();

            // Create the new work item
            WorkItem newWorkItem = workItemTrackingClient.CreateWorkItemAsync(patchDocument, project, type).Result;

            Console.WriteLine("Created work item ID {0} {1}", newWorkItem.Id, newWorkItem.Fields["System.Title"]);

            return newWorkItem;
        }
