Read XMl File data With namespace and without namespace

 

Suppose xml files is avaialble like this with namespace
<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns="http://abcd.org/onmags/schema">
  <AuthReq>
    <MyData>
      Hi How are you
    </MyData>
  </AuthReq>
</Document>

 
 .Net Sample Code looks like this 

  #region With Namespace
   XmlDocument doc = new XmlDocument();
   doc.Load(Server.MapPath("/Sample/request.xml"));

   var nms = new XmlNamespaceManager(doc.NameTable);
   nms.AddNamespace("nm", "http://abcd.org/onmags/schema");
   XmlNode node = doc.DocumentElement.SelectSingleNode("/nm:Document/nm:AuthReq", nms);

   //XmlNode node = doc.DocumentElement.SelectSingleNode("/Document/AuthReq");
   string request = node.InnerText.ToString();
  #endregion

Get Validation Error Message, Page.Isvaild False Section

if you wanted to know the route cause of error message then we can write below code in aso.net 

 foreach (BaseValidator validator in Page.Validators)

            {

                if (validator.Enabled && !validator.IsValid)

                {

                    // Put a breakpoint here

                    string clientID = validator.ClientID;

                    string aa = validator.ErrorMessage;

                }

            }

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);

SecurityProtocol Setting in .Net, SSL/TLS Error Fixes

 #region SecurityProtocol Setting

                try

                { //try TLS 1.3

                    ServicePointManager.SecurityProtocol = (SecurityProtocolType)12288

                                                         | (SecurityProtocolType)3072

                                                         | (SecurityProtocolType)768

                                                         | SecurityProtocolType.Tls;

                }

                catch (NotSupportedException)

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");

}

}
