.NET 实现Azure DevOps中通过API对工作项的ID列表获取

　　前言：最近在做对接Azure DevOps的API的工作，最开始也做了很多调研，官方给的API也是很丰富与完整，但是在对接工作项（WorkItems）时发现，官方并没有给WorkItems的列表或者分页的API，具体原因并不清楚，不过也可以通过id的list去获取工作项的list，id的list就需要通过wiql去获取。

　　这里对Azure DevOps的wiql进行分享，用作示例的是对工作项（WorkItems）的id的list进行获取，获取其他的id列表也可以类似使用。

 WorkItemSearch workItemSearch = new WorkItemSearch();

            IDictionary<string, object> SearchDic = new Dictionary<string, object>();
            SearchDic.Add(searchField, quaryItem);

            workItemSearch.SearchDic = SearchDic;

            QueryWiql queryWiql = new QueryWiql();

            var sql = $"SELECT [System.Id] FROM WorkItems WHERE [System.TeamProject] = '{ConfigManagerHelper.DevOpsProject()}'";

            if (workItemSearch != null)
            {
                if (workItemSearch.Id == 0)
                    sql += " AND [System.Id] > 0";
                else
                    sql += $" AND [System.Id] > {workItemSearch.Id}";

                foreach (var searchDic in workItemSearch.SearchDic)
                {
                    sql += $" AND [{searchDic.Key}] = '{searchDic.Value}'";
                }
            }

            sql += " order by [System.Id]";

            queryWiql.Query = sql;

            var httpContent = HttpJsonHelper.ObjectToByteArrayContent(queryWiql);

            var result = HttpJsonHelper.HttpPost(m_httpClientFactory,
                m_devOpsUrl,
                $"_apis/wit/wiql?$top={top}&api-version={ConfigManagerHelper.ApiVersion()}",
                httpContent,
                ConfigManagerHelper.BasicToken());
