How to call a function with struct as input? - asp.net

Question

Here is my struct definition, function and the portion calling the function.
public struct NewSigningRequest
{
public string SerialNumber;
//public string Requestor;
public string Sponsor;
public string Approver;
public string BusinessJustification;
public byte[] DebugFile;
public string DebugFileName;
public string FirmwareVersion;
public string FirmwareDescription;
public byte[] SmokeTestResult;
public string ProductName;
public string SigningType;
}
static public bool CreateSigningRequest(NewSigningRequest Request)
{
Request = new NewSigningRequest();
bool succeeded = false;
string sqlcmdString = sqlQueryNewSigningRequest;
SqlConnection con = new SqlConnection(connection);
SqlCommand Insertcmd = new SqlCommand(sqlcmdString, con);
SqlParameter SerialNumber = new SqlParameter("#SerialNumber", SqlDbType.NVarChar, 50);
SerialNumber.Value = Request.SerialNumber;
Insertcmd.Parameters.Add(SerialNumber);
SqlParameter Requestor = new SqlParameter("#Requestor", SqlDbType.NVarChar, 20);
Requestor.Value = GetRequestor.GetRequestorAlias();
Insertcmd.Parameters.Add(Requestor);
SqlParameter Sponsor = new SqlParameter("#Sponsor", SqlDbType.NVarChar, 20);
Sponsor.Value = Request.Sponsor;
Insertcmd.Parameters.Add(Sponsor);
SqlParameter BusinessJustification = new SqlParameter("#BusinessJustification", SqlDbType.NVarChar, 2000);
BusinessJustification.Value = Request.BusinessJustification;
Insertcmd.Parameters.Add(BusinessJustification);
SqlParameter DebugFile = new SqlParameter("#DebugFile", SqlDbType.VarBinary, 8000);
DebugFile.Value = Request.DebugFile;
Insertcmd.Parameters.Add(DebugFile);
SqlParameter DebugFileName = new SqlParameter("#DebugFileName", SqlDbType.NVarChar, 100);
DebugFileName.Value = Request.DebugFileName;
Insertcmd.Parameters.Add(DebugFileName);
SqlParameter ProductName = new SqlParameter("#ProductName", SqlDbType.NVarChar, 20);
ProductName.Value = Request.ProductName;
Insertcmd.Parameters.Add(ProductName);
SqlParameter SigningType = new SqlParameter("#SigningType", SqlDbType.NVarChar, 10);
SigningType.Value = Request.SigningType;
Insertcmd.Parameters.Add(SigningType);
SqlParameter FirmwareVersion = new SqlParameter("#FirmwareVersion", SqlDbType.NVarChar, 50);
FirmwareVersion.Value = Request.FirmwareVersion;
Insertcmd.Parameters.Add(FirmwareVersion);
SqlParameter FirmwareDescription = new SqlParameter("#FirmwareDescription", SqlDbType.NVarChar, 250);
FirmwareDescription.Value = Request.FirmwareDescription;
Insertcmd.Parameters.Add(FirmwareDescription);
SqlParameter SmokeTestResult = new SqlParameter("#SmokeTestResult", SqlDbType.VarBinary, 8000);
SmokeTestResult.Value = Request.SmokeTestResult;
Insertcmd.Parameters.Add(SmokeTestResult);
return succeeded;
}
this is how I am trying to call it
NewSigningRequest Request;
byte[] bin;
string FileName;
if (FileUpload.HasFile)
{
bin = new byte[FileUpload.PostedFile.ContentLength];
HttpPostedFile mybin = FileUpload.PostedFile;
FileName = mybin.FileName;
mybin.InputStream.Read(bin, 0, FileUpload.PostedFile.ContentLength);
}
else
{
bin = null;
FileName = "";
}
string NameAlias = #HttpContext.Current.User.Identity.Name;
int index = NameAlias.IndexOf("\\") + 1;
string sAlias = NameAlias.Substring(index);
byte[] SmokeTest;
if (FileUploadSTR.HasFile)
{
SmokeTest = new byte[FileUploadSTR.PostedFile.ContentLength];
HttpPostedFile mySmokeTest = FileUploadSTR.PostedFile;
mySmokeTest.InputStream.Read(SmokeTest, 0, FileUploadSTR.PostedFile.ContentLength);
}
else
{
SmokeTest = null;
}
Request.SerialNumber = TextBoxSerialNumber.Text;
Request.Sponsor = TextBoxSponsor.Text;
Request.BusinessJustification = TextBoxBJ.Text;
if (bin == null)
{
Request.DebugFile = new byte[0];
}
else
{
Request.DebugFile = bin;
}
Request.DebugFileName = FileName;
Request.FirmwareVersion = TextBoxFV.Text;
Request.FirmwareDescription = TextBoxFD.Text;
if (TextBoxSigningType.Text == string.Empty)
{
Request.SigningType = drp2.SelectedValue.ToString();
}
else
{
Request.SigningType = TextBoxSigningType.Text.ToUpper();
}
if (SmokeTest == null)
{
Request.SmokeTestResult = new byte[0];
}
else
{
Request.SmokeTestResult = SmokeTest;
}
SurfaceSignDBAccess.CreateSigningRequest(Request);
upon calling this function, gives error saying that "use of unassigned local variable 'Request'."
What should be the right way to call this function?

Answer 1

NewSigningRequest Request; - is never initialized in the method, before calling
SurfaceSignDBAccess.CreateSigningRequest(Request);
try this:
var request = new NewSigningRequest();// in the first line of code of the second code snippet.
And in the static method, remove the following code.
Request = new NewSigningRequest();
