How to break from the Catch block after throwing BadRequestException using C#

I have a method which needs to break after the BadRequestException() is thrown.
Currently after BadRequestException() is thrown, frontend shows loading bar buffering infinitely.
Please find my code below
public FeSite GetSiteBySiteId(string envCode, string siteId)
{
try
{
envCode.ThrowIfNull();
siteId.ThrowIfNull();
var watch = new Stopwatch();
watch.Start();
FeSite result = this.ExecuteAndParseWebRequestForEnv<FeSite>(envCode, $"sites/{siteId}", HttpMethod.Get);
this.LogService.Info($"FeeDataAcccess - GetSitebySiteId - {watch.ElapsedMilliseconds}ms");
return result;
}
catch (Exception e)
{
this.LogService.Error($"GetSiteBySiteId - {e.Message}");
throw new BadRequestException("Invalid siteId!");
}
}
Below method calls GetSiteBySiteId() method:
public string GetDevicesSerialNumberBySiteId(string envCode, string siteId)
{
var siteSerialNumber = "";
if (siteId != null)
{
var result = this.feeDataAccess.GetSiteBySiteId(envCode, siteId);
List<string> gatewaySiteSNlist = result.Gateways.Select(x => x.SerialNumber).ToList();
foreach (var item in gatewaySiteSNlist)
{
var siteSN = item;
siteSerialNumber += $";{siteSN};";
}
}
return siteSerialNumber;
}
I have tried this code below :
public FeSite GetSiteBySiteId(string envCode, string siteId)
{
do
{
try
{
envCode.ThrowIfNull();
siteId.ThrowIfNull();
var watch = new Stopwatch();
watch.Start();
FeSite result = this.ExecuteAndParseWebRequestForEnv<FeSite>(envCode, $"sites/{siteId}", HttpMethod.Get);
this.LogService.Info($"FeeDataAcccess - GetSitebySiteId - {watch.ElapsedMilliseconds}ms");
return result;
}
catch (Exception e)
{
this.LogService.Error($"GetSiteBySiteId - {e.Message}");
throw new BadRequestException("Invalid siteId!");
}
}
while (false);
{
break;
}
}
But I get error "No enclosing loop out of which to break or continue"
How to fix this? Thanks in advance.

public string GetDevicesSerialNumberBySiteId(string envCode, string siteId)
{
var siteSerialNumber = "";
if (siteId != null)
{
try{
var result = this.feeDataAccess.GetSiteBySiteId(envCode, siteId);
List<string> gatewaySiteSNlist = result.Gateways.Select(x => x.SerialNumber).ToList();
foreach (var item in gatewaySiteSNlist)
{
var siteSN = item;
siteSerialNumber += $";{siteSN};";
}
}catch{
//BadRequestException catch and error handling goes here
}
}
return siteSerialNumber;
}

You are confronted to the classic issue of external and internal values in SAP.
Your screenshot shows the ABAP Function Module Test screen in SAP system. When you enter a value in the screen, it may be transformed internally before calling the function module.
These are called the external and internal formats. "External" is what is shown in the User Interface (typed or displayed), "internal" is the value written to the database.
For instance, imagine a database object whose primary key is a GUID, this is the object key in internal format, but in the user interface this object is always referred or shown by its name (candidate key).
In your precise case, when a Production Order is a number, the internal format always contains leading zeroes on 12 digits, and the external format does not display them. In the Function Module Test screen, if you enter this external value:
1000262
it's converted to the following internal value and the BAPI is called with it:
000001000262
Generally speaking, when you call any function module from another program, you must indicate the internal value, because there's no user interface implied between the two.
i.e., use this XML in your method testConnection:
string rfcRequest = "<bapi_prodord_get_detail><number>000001000262</number><struct>"
+ "<order_objects><header>X</header><operations>X</operations><components>X"
+ "</components></order_objects></struct></bapi_prodord_get_detail>";
See also this answer about external and internal formats: Converting MATNR via conversion exit fails for custom table

If you would like to do the required field conversions programmatically, which are explained in Sandra Rossi's answer, you may use the RFMs BAPI_CONVERSION_EXT2INT, BAPI_CONVERSION_EXT2INT1, BAPI_CONVERSION_INT2EXT and BAPI_CONVERSION_INT2EXT1 for doing so.
However, every additional RFC call has of course a negative impact on the performance.
Besides, SAP Note 206068 is a good resource for an explanation of some RFC BAPI pitfalls which you also stepped in.

SSRS wont publish report but it returns successful as if it did

public static void ListFolders()
{
HomeFolderListing = new List<string>();
ReportingServiceSoapClient rs = new ReportingServiceSoapClient();
rs.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation;
CatalogItem[] HomeFolders = null;
string reportPath = "/";
rs.ListChildren(reportPath, true, out HomeFolders);
foreach (var homeF in HomeFolders)
{
if (homeF.Name.ToString().ToLower().Contains("base"))
{
if (homeF.Path.ToString().ToLower().Contains("/data sources/"))
{
}
else
{
Console.WriteLine("Adding reporting folder: " + homeF.Name.ToString());
HomeFolderListing.Add(homeF.Path.ToString());
}
}
}
}
public static void PublishReport()
{
foreach (string HomeFold in HomeFolderListing)
{
ReportingServiceSoapClient rs = new ReportingServiceSoapClient();
rs.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation;
BatchHeader bh = new BatchHeader();
string batchID = null;
rs.CreateBatch(out batchID);
bh.BatchID = batchID;
Byte[] definition = null;
Warning[] warnings = null;
try
{
FileStream stream = File.OpenRead(ReportInformation.Report2Deploy);
definition = new Byte[stream.Length];
stream.Read(definition, 0, (int)stream.Length);
stream.Close();
}
catch (Exception ex)
{
}
try
{
string filename = ReportInformation.ReportDeployNameOnly;
Console.WriteLine("Deploying Report: " + filename + " to: " + HomeFold);
rs.CreateReport(bh, filename, HomeFold, true, definition, null, out warnings);
if (warnings != null)
{
foreach (Warning warning in warnings)
{
Console.WriteLine(warning.Message);
}
}
else
Console.WriteLine("Report: {0} created successfully with no warnings", filename);
}
catch (Exception ex)
{
}
}
}
when i execute rs.CreateReport() it comes back as if it was successful with no warning, however, when i view the server it just isn't there. And yes I've looking in all the folders.

Are you sure there is no error? There's an empty catch block. The documenation says to catch a SoapException. Try this in the catch:
catch (SoapException e)
{
//Do something with the error, sample code write to console
Console.WriteLine(e.Detail.InnerXml.ToString());
}

This IfxTransaction has completed; it is no longer usable

Q:
When I use the transactions ,I'll get the following error on about 1 out of every 100 record.
This IfxTransaction has completed; it
is no longer usable
I can't expect when the error happen or what is the reason of this error.
I try to insert about 607 record in the same transaction.
My code:
public static int InsertGroups(List<Group> groups)

try

foreach (Group a in groups)
{
groupsParameter.Add("id", a.GroupId.ToString());
groupsParameter.Add("name", a.Name);

}
}
return return_val;
}

You seem to be handling errors and rolling back the transaction in two places (in Execute_NonQueryWithTransaction and in InsertGroups.
And the return from Execute_NonQueryWithTransaction is used both to return error codes and to return rows affected. But in InsertGroups it is checked purely as a rows affected.
Could you have an error code from Execute_NonQueryWithTransaction (so transaction rolled back) being treated as success (rows inserted) in InsertGroups and the commit then fails?
Overall the code needs significant cleanup:
A catch block to only throw is pointless and just adds noise.
Just use exceptions for error handling, all normal returns should indicate success.

Why do I get the error DTD is not allowed on this document?

I don't think you gave us the actual XML document that you are reading. It probably has a "DOCTYPE" at the top which specifies a .DTD file.
Either edit the document to not have the DOCTYPE, or programatically ignore the DOCTYPE. Here is how you can do that: Ignore DOCTYPE .dtd, but .dtd file must still exist
