In web Api 2 RDLC report controller why can't i return to FILE?

what i am trying to do is to generate a PDF/Excel report in mvc web API 2 and view in a new tab in a browser.
My error says 'Non-invocable member 'File' cannot be used like a method'.
did i miss a namespace or a assembly?
any help is much appreciated.
Here is My code:
'''

{
var fromDate = "01/01/2000";
var toDate = DateTime.Now.ToShortDateString();
var id = "PDF";
var result = new ApiResult();
var lr = new LocalReport();
var path = Path.Combine(HttpContext.Current.Server.MapPath("~/Reports"), "Test.rdlc");
if (System.IO.File.Exists(path))
{
lr.ReportPath = path;
}
else
{
result.Status = ApiResult.ApiStatus.Error;
result.Message = "Report Error";
return Ok(result);
}
if (fromDate == "" && toDate == "")
{
fromDate = "01/01/2000";

return File(renderedBytes, mimeType);
} '''

FileContentResult is MVC Action Result. You don't File (FileContentResult) in WebAPI.
Please modify your last return statement(return File(renderedBytes, mimeType)) as follows:
var result = new HttpResponseMessage(HttpStatusCode.OK)
{
Content = new ByteArrayContent(renderedBytes)
};
result.Content.Headers.ContentType = new MediaTypeHeaderValue(mimeType); //"application/pdf"
var input = $"inline; filename={fileNameExtension}"; //where fileNameExtension something with file name and extension for e.g., myfilename.txt
ContentDispositionHeaderValue contentDisposition;
if (ContentDispositionHeaderValue.TryParse(input, out contentDisposition))
{
result.Content.Headers.ContentDisposition = contentDisposition;
}
return this.ResponseMessage(result);

c# - How to call/link a workflow on a web application from a c# program?

I have a C# (WinForms) application that can scan documents via a printer. After scanning, I will be able to enter document details on it and have a button to finalize the documents. The documents details and info will be stored in my database ABC in certain tables.
Now, I have another web application written in Java(IntelliJ) that has some button functionality to upload documents and then start a workflow and route it to another user to approve the document. I won't go into detail on the specifics. This application also connects to the same database ABC.
So now comes the tougher part, I need to link these two applications in a way that when I finalize my document
on the C# application, it has to auto trigger the workflow on the web application side. Rather than manually starting the workflow on the web application, it would just call or trigger the workflow, so I do not need to access the web application at all for the process to start.

Is there a way I could call this from the C# application?

You can send your file directly from your C# app with use of Http client. Here is code sample:
private async Task<bool> Upload(string filePath)
{
const string actionUrl = #"http://126.32.3.178:8111/process/taskmanager/start/start.jsp";
var fileName = Path.GetFileName(filePath);
var fileBytes = File.ReadAllBytes(filePath);
var fileContent = new ByteArrayContent(fileBytes);
using (var client = new HttpClient())
using (var formData = new MultipartFormDataContent())
{
formData.Add(fileContent, fileName);
var response = await client.PostAsync(actionUrl, formData);
return response.IsSuccessStatusCode;
}
}
Also, note that there maybe some sort of authentication should be performed before you can post a request.

LinQtoExcel using asp fileupload

im having problems with this function. so basically a user will upload an excel file .xls (2003 version) then once the import button is clicked it will read the excel file and import it into the sql database.
here is my code
protected void btnImport_Click(object sender, EventArgs e)
{
Business.Student student = new Business.Student();
int errorCount = 0;
int successCount = 0;
string successTotal;
int missinglastname = 0;
int missingfirstname = 0;
int missingmiddlename = 0;
if (filebiometrics.HasFile == false)
{
}
else
{
string pathToExcelFile = filebiometrics.FileName;
var excelFile = new ExcelQueryFactory(pathToExcelFile);
IEnumerable<string> worksheetnames = excelFile.GetWorksheetNames();
string worksheetName = excelFile.GetWorksheetNames().ToArray()[0];
var import = from a in excelFile.Worksheet<Business.Student.StudentList>(worksheetName) select a;
//var emptyfield = excelFile.Worksheet<Business.Employees.EmployeeImport>().Where(x => x.Surname != null).ToList();
excelFile.AddMapping<Business.Student.StudentList>(x => x.studentnumber, "Student Number");
excelFile.AddMapping<Business.Student.StudentList>(x => x.firstname, "Firstname");
excelFile.AddMapping<Business.Student.StudentList>(x => x.lastname, "Lastname");
excelFile.AddMapping<Business.Student.StudentList>(x => x.middlename, "Middlename");
string missing = "Missing!";
foreach (var a in import)
{
if (a.studentnumber == 0)
{
}
if (a.lastname == null)
{
a.lastname = missing;
missinglastname = missinglastname + 1;
}
if (a.firstname == "")
{
a.firstname = missing;
missingfirstname = missingfirstname + 1;
}
if (a.middlename == null)
{
missingmiddlename = missingmiddlename + 1;
}
else if (student.CheckExistingStudentNumber(a.studentnumber))
{
errorCount = errorCount + 1;
}
else
{
student.Create(a.studentnumber, a.firstname, a.lastname, a.middlename);
successCount = successCount + 1;
successTotal = "Total imported record: " + successCount.ToString();
}
}
txtLog.InnerText = "Total duplicate record: " + errorCount.ToString() +
Environment.NewLine +
"Total missing data on Firstname column: " + missingfirstname.ToString() +
Environment.NewLine +
"Total missing data on Lastname column: " + missinglastname.ToString() +
Environment.NewLine +
"Total missing data on middlename column: " + missingmiddlename.ToString() +
Environment.NewLine +
Environment.NewLine +
"Total imported record: " + successCount.ToString();
filebiometrics.Attributes.Clear();
}
}
im always getting this error
the error is in this line 'IEnumerable worksheetnames = excelFile.GetWorksheetNames();'
can somebody help me with this?

Your error message is self explanatory. Error is at this line:-
var excelFile = new ExcelQueryFactory(pathToExcelFile);
ExcelQueryFactory expects the full file path but you are just passing the excel file name using string pathToExcelFile = filebiometrics.FileName; and obviously it is not able to read the file.
You need to read the excel file which user is uploading and save it to the server and then read it like this:-
string filename = Path.GetFileName(filebiometrics.FileName);
filebiometrics.SaveAs(Server.MapPath("~/") + filename);
var excelFile = new ExcelQueryFactory(Server.MapPath("~/") + filename);

set multiple parameter in recursive c#

when I make 2 parameters. when the cursor on highlight ahref not getting value, as the first parameter? but always get the value of its parent.
What should I do with my code below:
please help correct the errors / shortcomings of my code.
private string LoadNavigasi(string kodeJabatan, ref int countLoop)
{
if (kodeJabatan == null)
kodeJabatan = "001";
DataSet ds = RunQuery("Select KodePosition,NamaPosition,Parent from Position where KodePosition = '" + kodeJabatan + "'");
string temp = string.Empty;
string tempP = string.Empty;
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
var kode = ds.Tables[0].Rows[i][0].ToString();
var nama = ds.Tables[0].Rows[i][1].ToString();
var parent = ds.Tables[0].Rows[i][2].ToString();
if (parent == "")
parent = null;
temp = string.Format("{0}", nama);
tempP = string.Empty;
countLoop++;
if (parent != null)
{
tempP = string.Format("{0}", LoadNavigasi(parent, ref countLoop));
temp = string.Format("{1}<ul><li>{0}", temp, tempP);
}
else
{
temp = string.Format("{0}", temp);
}
return temp;
}
return temp;
}

I'm not sure if it helps but I simplify your code to what it's actually doing.
private string LoadNavigasi(string kodeJabatan)
{
if (kodeJabatan == null)
kodeJabatan = "001";
DataSet ds = RunQuery("Select KodePosition,NamaPosition,Parent from Position where KodePosition = '" + kodeJabatan + "'");
var kode = ds.Tables[0].Rows[0][0].ToString();
var nama = ds.Tables[0].Rows[0][1].ToString();
var parent = ds.Tables[0].Rows[0][2].ToString();
string temp = string.Format("<a href=?Kode={0}&Name={1}>{1}</a>", kode, nama);
if (string.IsNullOrEmpty(parent))
{
string tempP = LoadNavigasi(parent);
temp = string.Format("{1}<ul><li>{0}", temp, tempP);
}
return temp;
}
You mention something about your second parameter in the line
temp = string.Format("{0}", nama);
The second parameter is nama but I don't understand what's wrong with it.
