Session Kill on Page Refresh OR On Page/Browser refresh session kill in asp.net with c#
Create a Global Variable
bool IsPageRefresh = false;
Write Below Code on Page Load
#region To Maintain Refresh event //Section of code checks if the page postback is due to genuine submit by user //or by pressing "refresh" or F5 if (!IsPostBack) { //Session.Abandon(); Session.Clear(); ViewState["ViewStateId"] = System.Guid.NewGuid().ToString(); Session["SessionId"] = ViewState["ViewStateId"].ToString(); } else { if (ViewState["ViewStateId"] != null && Session["SessionId"] != null) { if (ViewState["ViewStateId"].ToString() != Session["SessionId"].ToString()) { IsPageRefresh = true; } } Session["SessionId"] = System.Guid.NewGuid().ToString(); ViewState["ViewStateId"] = Session["SessionId"].ToString(); } #endregion
Check Global variable where you made the condition like on events
#region To Maintain Refresh event if (IsPageRefresh) { Session.Abandon(); Session.Clear(); } #endregion if (Session["MyFlag"] == null) Response.Redirect("invalid.aspx?msg=Session expired. ", true);

Received an invalid column length from the bcp client for colid Error while Bulk Upload in aspx c#
I have created sample code to know the route cause of this issue.
So we can write code like this.
Sample code:-
#region bulkCopy
if (MyConnection.State == ConnectionState.Closed) MyConnection.Open();
DataTable dataTableName = GetDataTabletFromCSVFile(filenamestr1);
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(MyConnection))
{
bulkCopy.DestinationTableName = "Destination_TBL_My_Name_Temp";
try
{
bulkCopy.WriteToServer(dataTableName);
}
catch (Exception ex)
{
WriteErrorLog_Debug("My_FileExtractService " + ex.Message.ToString() + " " + ex.StackTrace.ToString() + " / " + RefNo, "testTimer_Elapsed1");
string message = "";
if (ex.Message.Contains("Received an invalid column length from the bcp client for colid"))
{
string pattern = @"\d+";
Match match = Regex.Match(ex.Message.ToString(), pattern);
var index = Convert.ToInt32(match.Value) - 1;
FieldInfo fi = typeof(SqlBulkCopy).GetField("_sortedColumnMappings", BindingFlags.NonPublic | BindingFlags.Instance);
var sortedColumns = fi.GetValue(bulkCopy);
var items = (Object[])sortedColumns.GetType().GetField("_items", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(sortedColumns);
FieldInfo itemdata = items[index].GetType().GetField("_metadata", BindingFlags.NonPublic | BindingFlags.Instance);
var metadata = itemdata.GetValue(items[index]);
var column = metadata.GetType().GetField("column", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance).GetValue(metadata);
var length = metadata.GetType().GetField("length", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance).GetValue(metadata);
message = (String.Format("Column: {0} contains data with a length greater than: {1}", column, length));
}
string aa = message;
WriteErrorLog_Debug("My_FileExtractService Detailed Exception " + message.ToString() + " " + ex.StackTrace.ToString() + " / " + RefNo, "testTimer_Elapsed1");
}
}

Get Web Request Error 500,400 Exception details in c#
WebException is a good approch to get the Real cause of 500 error,
catch (WebException ex)
{
using (var stream = ex.Response.GetResponseStream())
using (var reader = new StreamReader(stream))
{
Console.WriteLine(reader.ReadToEnd());
}
}
catch (Exception ex)
{
// Something more serious happened
// like for example you don't have network access
// we cannot talk about a server exception here as
// the server probably was never reached
}
