guyz我知道如何從我的列表中添加數據,但問題是如何檢索它...?如何從我的列表中獲取數據<T>
ID delcared我在GlobalVar.cs名單:
public static List<string> ViolationRefNumToPrint = new List<string>();
這裏的代碼後面添加數據到我的清單.....
GlobalVar.ViolationRefNumToPrint.Clear();
for (int i = 0; i < lvviolations.Items.Count; i++)
{
GlobalVar.ViolationRefNumToPrint.Add(((EmpViolationObject)lvviolations.Items[i]).VioRefNum);
}
我的問題是我怎麼能檢索我的列表... :(

guyz我已經使用下面的代碼。這是由@evanmcdonnal給出的。其實我要去使用這個對我的報告...我已經使用的DocumentViewer
這裏是我的代碼....
ReportDocument reportDocument = new ReportDocument();
string ats = new DirectoryInfo(Environment.CurrentDirectory).Parent.Parent.FullName;
StreamReader reader = new StreamReader(new FileStream(ats.ToString() + @"\Template\ReportViolation.xaml", FileMode.Open, FileAccess.Read));
reportDocument.XamlData = reader.ReadToEnd();
reportDocument.XamlImagePath = Path.Combine(ats.ToString(), @"Template\");
reader.Close();
DateTime dateTimeStart = DateTime.Now; // start time measure here
List<ReportData> listData = new List<ReportData>();
int i = 0;
foreach (string item in GlobalVar.ViolationRefNumToPrint)
{
ReportData data = new ReportData();
data.ReportDocumentValues.Add("PrintDate", DateTime.Now);
data.ReportDocumentValues.Add("EmpIDNum", NewIDNumber.ToString());
data.ReportDocumentValues.Add("EmpName", NewEmpName.ToString());
data.ReportDocumentValues.Add("EmpPosition", NewPosition.ToString());
data.ReportDocumentValues.Add("PageNumber",(i + 1));
data.ReportDocumentValues.Add("PageCount", GlobalVar.ViolationRefNumToPrint.Count.ToString());
listData.Add(data);
i++;
}
XpsDocument xps = reportDocument.CreateXpsDocument(listData);
documentViewer.Document = xps.GetFixedDocumentSequence();
// show the elapsed time in window title
Title += " - generated in " + (DateTime.Now - dateTimeStart).TotalMilliseconds + "ms";
這裏的問題是,它給的我的錯誤是這樣....
找回什麼到你的列表。如果你的意思是訪問的項目?在你的列表中,只需遍歷它 – Bernard
檢索它做什麼?顯示值? – fsimonazzi
'ViolationRefNumToPrint [listIndex];'或迭代它:'foreach(var vioRefNum in ViolationRefNumToPrint){/ }' –
