[英]Not able to access the Assigned To field of a Azure DevOps Work Item
I am creating a console application in visual studio to get the work item details from a Azure DevOps project. 我正在Visual Studio中创建一个控制台应用程序,以从Azure DevOps项目获取工作项详细信息。 I am not able to access the
AssignedTo
field of a Work item. 我无法访问工作项的
AssignedTo
字段。
I tried using the code in Microsoft page to query work items with some changes and Its showing a exception when I try to access the AssignedTo
field. 我尝试使用Microsoft页面中的代码来查询具有一些更改的工作项,并且当我尝试访问
AssignedTo
字段时显示异常。
static void Main(string[] args)
{
string _uri = "https://dev.azure.com/xyz";
string _personalAccessToken =
"xpdrix7nyspotj3l4gotvvk4cpp2z6l65g5r";
string _project = "FirstProject";
Uri uri = new Uri(_uri);
string personalAccessToken = _personalAccessToken;
string project = _project;
VssBasicCredential credentials = new VssBasicCredential("",
_personalAccessToken);
//create a wiql object and build our query
Wiql wiql = new Wiql()
{
Query = "Select *" +
"From WorkItems " +
"Where [System.TeamProject] = '" + project + "' " +
"Order By [State] Asc, [Changed Date] Desc"
};
//create instance of work item tracking http client
sing (WorkItemTrackingHttpClient workItemTrackingHttpClient =
new WorkItemTrackingHttpClient(uri, credentials))
{
//execute the query to get the list of work items in the results
WorkItemQueryResult workItemQueryResult =
workItemTrackingHttpClient.QueryByWiqlAsync(wiql).Result;
//some error handling
if (workItemQueryResult.WorkItems.Count() != 0)
{
//need to get the list of our work item id's and put them
//into an array
List<int> list = new List<int>();
foreach (var item in workItemQueryResult.WorkItems)
{
list.Add(item.Id);
}
int[] arr = list.ToArray();
//build a list of the fields we want to see
string[] fields = new string[3];
fields[0] = "System.Id";
fields[1] = "System.Title";
fields[2] = "System.AssignedTo";
WorkItemExpand workItemExpand = WorkItemExpand.All;
//get work items for the id's found in query
var workItems =
workItemTrackingHttpClient.GetWorkItemsAsync(arr, fields=null, workItemQueryResult.AsOf,workItemExpand).Result;
Console.WriteLine("Query Results: {0} items found", workItems.Count);
//loop though work items and write to console
foreach (var workItem in workItems)
{
Console.WriteLine("{0}{1}{2}", workItem.Id, workItem.Fields["System.Title"], workItem.Fields["System.AssignedTo"]);
}
}
}
}
}
The error is: 错误是:
System.Collections.Generic.KeyNotFoundException HResult=0x80131577 Message=The given key was not present in the dictionary.
System.Collections.Generic.KeyNotFoundException HResult = 0x80131577 Message =字典中不存在给定的键。 Source=mscorlib StackTrace: at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at ScrumBoard.Program.Main(String[] args) in C:\\Users\\Naresh\\source\\repos\\ScrumBoard\\ScrumBoard\\Program.cs:line 84
Source = mscorlib StackTrace:位于System.Collections.Generic.Dictionary`2.get_Item(TKey键)位于ScrumBoard.Program.Main(String [] args)在C:\\ Users \\ Naresh \\ source \\ repos \\ ScrumBoard \\ ScrumBoard \\ Program .cs:第84行
It's because when you get the work items you specify fields = null
. 这是因为当您获得工作项时,您指定了
fields = null
。
You need just to give the id's without any additional parameters: 您只需要提供ID,而无需任何其他参数:
var workItems = workItemTrackingHttpClient.GetWorkItemsAsync(arr).Result;
Now you will get all the fields including System.AssignedTo
. 现在,您将获得所有字段,包括
System.AssignedTo
。
This was the new code: 这是新的代码:

}
}
}
Console.ReadLine();
}
System.Collections.Generic.KeyNotFoundException
exception will be thrown out if the assigned to
field is Unassigned. 如果
assigned to
字段为Unassigned,将抛出System.Collections.Generic.KeyNotFoundException
异常。
Please check if the assigned to
field is assigned in your queried work item. 请检查
assigned to
字段是否已在您查询的工作项目中分配。
You code is Ok, Except i cannot compile workItemQueryResult.WorkItems.Count()
, I casted it to IList<> instead. 您的代码还可以,除非我无法编译
workItemQueryResult.WorkItems.Count()
,但我将其workItemQueryResult.WorkItems.Count()
为IList <>。 ((IList<WorkItemReference>)workItemQueryResult.WorkItems).Count()
