我已经被困在这个问题上一天左右,需要一些帮助。在我的应用程序中,我在listview中有一些数据,这是
public void OnHostPing(HostPinger host)
{
if (InvokeRequired)
{
Invoke(new OnPingDelegate(OnHostPing), new object[] { host });
return;
}
lock (_table)
{
ListViewItem item = (ListViewItem)_table[host.ID];
if (item != null)
{
item.SubItems[0].Text = host.HostIP.ToString();
item.SubItems[1].Text = host.HostName;
item.SubItems[2].Text = host.HostDescription;
item.SubItems[3].Text = host.StatusName;
item.SubItems[4].Text = host.SentPackets.ToString();
item.SubItems[5].Text = host.ReceivedPackets.ToString();
item.SubItems[6].Text = PercentToString(host.ReceivedPacketsPercent);
item.SubItems[7].Text = host.LostPackets.ToString();
item.SubItems[8].Text = PercentToString(host.LostPacketsPercent);
item.SubItems[9].Text = host.LastPacketLost ? "Yes" : "No";
item.SubItems[10].Text = host.ConsecutivePacketsLost.ToString();
item.SubItems[11].Text = host.MaxConsecutivePacketsLost.ToString();
item.SubItems[12].Text = host.RecentlyReceivedPackets.ToString();
item.SubItems[13].Text = PercentToString(host.RecentlyReceivedPacketsPercent);
item.SubItems[14].Text = host.RecentlyLostPackets.ToString();
item.SubItems[15].Text = PercentToString(host.RecentlyLostPacketsPercent);
item.SubItems[16].Text = host.CurrentResponseTime.ToString();
item.SubItems[17].Text = host.AverageResponseTime.ToString("F");
item.SubItems[18].Text = host.MinResponseTime.ToString();
item.SubItems[19].Text = host.MaxResponseTime.ToString();
item.SubItems[20].Text = DurationToString(host.CurrentStatusDuration);
item.SubItems[21].Text = DurationToString(host.GetStatusDuration(HostStatus.Alive));
item.SubItems[22].Text = DurationToString(host.GetStatusDuration(HostStatus.Dead));
item.SubItems[23].Text = DurationToString(host.GetStatusDuration(HostStatus.DnsError));
item.SubItems[24].Text = DurationToString(host.GetStatusDuration(HostStatus.Unknown));
item.SubItems[25].Text = PercentToString(host.HostAvailability);
item.SubItems[26].Text = DurationToString(host.TotalTestDuration);
item.SubItems[27].Text = DurationToString(host.CurrentTestDuration);
}
else
{
item = new ListViewItem(new string[]
{
host.HostIP.ToString(), host.HostName, host.HostDescription,
host.StatusName,
host.SentPackets.ToString(),
host.ReceivedPackets.ToString(), PercentToString(host.ReceivedPacketsPercent),
host.LostPackets.ToString(), PercentToString(host.LostPacketsPercent),
host.LastPacketLost ? "Yes" : "No",
host.ConsecutivePacketsLost.ToString(), host.MaxConsecutivePacketsLost.ToString(),
host.RecentlyReceivedPackets.ToString(), PercentToString(host.RecentlyReceivedPacketsPercent),
host.RecentlyLostPackets.ToString(), PercentToString(host.RecentlyLostPacketsPercent),
host.CurrentResponseTime.ToString(), host.AverageResponseTime.ToString("F"),
host.MinResponseTime.ToString(), host.MaxResponseTime.ToString(),
DurationToString(host.CurrentStatusDuration),
DurationToString(host.GetStatusDuration(HostStatus.Alive)),
DurationToString(host.GetStatusDuration(HostStatus.Dead)),
DurationToString(host.GetStatusDuration(HostStatus.DnsError)),
DurationToString(host.GetStatusDuration(HostStatus.Unknown)),
PercentToString(host.HostAvailability),
DurationToString(host.TotalTestDuration),
DurationToString(host.CurrentTestDuration)
});
我似乎无法弄清楚的是,如何将数据导出到Excel?我可以使用此代码将静态数据导出到Excel
public static string RunSample1(DirectoryInfo outputDir)
{
if (!outputDir.Exists) throw new Exception("outputDir does not exist!");
FileInfo newFile = new FileInfo(outputDir.FullName + @"\sample1.xlsx");
if (newFile.Exists)
{
newFile.Delete(); // ensures we create a new workbook
newFile = new FileInfo(outputDir.FullName + @"\sample1.xlsx");
}
using (ExcelPackage package = new ExcelPackage(newFile))
{
// add a new worksheet to the empty workbook
ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Current Devices");
//Add the headers
//worksheet.Cells[1, 1].Value = "ID";
worksheet.Cells[1, 1].Value = "";
worksheet.Cells[1, 2].Value = "Product";
worksheet.Cells[1, 3].Value = "Quantity";
worksheet.Cells[1, 4].Value = "Price";
worksheet.Cells[1, 5].Value = "Value";
//Add some items...
worksheet.Cells["A2"].Value = 12001;
worksheet.Cells["B2"].Value = "Nails";
worksheet.Cells["C2"].Value = 37;
worksheet.Cells["D2"].Value = 3.99;
我无法弄清楚如何将这些listview项目放入电子表格单元格而不是静态数据。 ListViewItems似乎没有产生我期望的属性。有人可以帮我一点吗?
