[英]how to Show progress Bar In Display While Executing Method in c#
在我的应用程序中,我想在用户单击“特定按钮”时显示“进度条”,
我实现了以下代码
private bool ImportData()
{
bool result = false;
//Thread oThread = new Thread(new ThreadStart(frmWaitShow));
try
{
Thread backgroundThread = new Thread(
new ThreadStart(() =>
{
//oThread.Start();
for (int n = 0; n < 100; n++)
{
Thread.Sleep(50);
progressBar1.BeginInvoke(new Action(() => progressBar1.Value = n));
}
}
));
backgroundThread.Start();
// Progress Bar Should Start From here
intdevid = int.Parse(cmbDeviceName.SelectedValue.ToString());
FetchDevicedata(intdevid); // Fetch Remove Device Info from SQL database
//FTPTCompletedBatchTransfer();
FetchMaxReportId();
GetFTPFile(strDeviceIP, strDeviceUsername, strDevicePwd, strDevicePath + "//RunningBatch//RunningBatch.db", "RunningBatch.db"); // Copy RunningBatch.db to Debug Folder from Remote
LoadRunningData(); // Get Running Data in dataset from running.db
DecodeBatchData_R(); // save in batch master and row data table
GetFTPFile(strDeviceIP, strDeviceUsername, strDevicePwd, strDevicePath + "//CompletedBatch//CompletedBatch.db", "CompletedBatch.db");
LoadCompletedData();
DecodeBatchData();
result = true;
// Progress Bar Should Stop here
}
catch (Exception ex)
{
clsLogs.LogError("Error: " + ex.Message + this.Name + " || ImportData");
result = false;
}
//oThread.Abort();
return result;
}
但是它不能正确显示..要花费很多时间才能启动此进度条,请在我的这些功能刚刚结束之前开始并在2秒内关闭
您可以使用BackgroundWorker
,它支持进度指示。
