I have a Web API controller method...
[HttpGet]
[Route("~/Api/Tag/GetTagTaskMappings")]
public IHttpActionResult GetTagTaskMappings()
{
try
{
var tagTaskMappings = _tagRepository.GetTagTaskMappings();
if (tagTaskMappings == null)
{
return NotFound();
}
return Ok(tagTaskMappings);
}
catch (Exception ex)
{
return InternalServerError(ex.InnerException);
}
}
I am using Postman to debug the method.
I am testing the Web API in 2 scenarios...
Running in Visual Studio (IIS Express)
Running on IIS Manager on a remote server
Using Postman I get the desired results from scenario 1 test...
{
"Message": "An error has occurred.",
"ExceptionMessage": "No Tag/Task Relationship found",
"ExceptionType": "System.Data.SqlClient.SqlException",

}
However, for scenario 2 test, I only get this back from Postman...
{
"Message": "An error has occurred."
}
Any idea why I am not getting the ExceptionMessage? Am I error handling correctly?
The only difference I see in Postman is scenario 1 has one extra header...

I have a SQL Server stored procedure that is used for uploading a document and returns an ID upon success.
I am storing the parameter file_data into a byte[] type in the Customer_Document_ADD class.
public byte[] file_data { get; set; }
The following is my repository code.
public async Task<int> InsertCustomer_Document_ADDResult(Customer_Document_ADD customer_Document_ADDED)
{
await using(SqlConnection connection = new SqlConnection(_connectionString))
{
connection.Open();
// define SqlParameters for the other two params to be passed
var company_idParam = new SqlParameter("#company_id", customer_Document_ADDED.company_id);
var customer_idParam = new SqlParameter("#customer_id", customer_Document_ADDED.customer_id);
var customer_site_idParam = new SqlParameter("#customer_site_id", customer_Document_ADDED.customer_site_id);
var customer_system_idParam = new SqlParameter("#customer_system_id", customer_Document_ADDED.customer_system_id);
var job_idParam = new SqlParameter("#job_id", customer_Document_ADDED.job_id);
var security_levelParam = new SqlParameter("#security_level", customer_Document_ADDED.security_level);
var file_nameParam = new SqlParameter("#file_name", customer_Document_ADDED.file_name);
var file_sizeParam = new SqlParameter("#file_size", customer_Document_ADDED.file_size);
var upload_dateParam = new SqlParameter("#upload_date", customer_Document_ADDED.upload_date);
var document_extParam = new SqlParameter("#document_ext", customer_Document_ADDED.document_ext);
var user_codeParam = new SqlParameter("#user_code", customer_Document_ADDED.user_code);
var user_descriptionParam = new SqlParameter("#user_description", customer_Document_ADDED.user_description);
var reference1Param = new SqlParameter("#reference1", customer_Document_ADDED.reference1);
var reference2Param = new SqlParameter("#reference2", customer_Document_ADDED.reference2);
var reference3Param = new SqlParameter("#reference3", customer_Document_ADDED.reference3);
var reference4Param = new SqlParameter("#reference4", customer_Document_ADDED.reference4);
var file_dataParam = new SqlParameter("#file_data", customer_Document_ADDED.file_data);
//if (file_dataParam.Value == null)
//{
// file_dataParam.Value = "";
//}
file_dataParam.SqlDbType = SqlDbType.Image;
// define the output parameter that needs to be retained
// for the Id created when the Stored Procedure executes
// the INSERT command
var document_idParam = new SqlParameter("#document_id", SqlDbType.Int);
// the direction defines what kind of parameter we're passing
// it can be one of:
// Input
// Output
// InputOutput -- which does pass a value to Stored Procedure and retains a new state
document_idParam.Direction = ParameterDirection.Output;
// we can also use context.Database.ExecuteSqlCommand() or awaitable ExecuteSqlCommandAsync()
// which also produces the same result - but the method is now marked obselete
// so we use ExecuteSqlRawAsync() instead
// we're using the awaitable version since GetOrCreateUserAsync() method is marked async
await context.Database.ExecuteSqlRawAsync(

}
}
I'm getting the following error in Postman.

All other values are captured except the file. I am getting a null value in the debugger. Why am I unable to upload a file into the database? Thanks in advance.
Firstly,default model binding system cannot bind file to byte[] properties.If you want to bind file to btye[],you can use ByteArrayModelBinder,here is an official link.
Also,if you don't mind to change the type of file_data,you can use
public IFormFile file_data { get; set; }
and then you can convert it to byte[] type with MemoryStream.Here is an official link about upload files in .net core.
I'm creating a web application for the parish in angular.
It is a CRUD web application in which I use SQL Server.
I have the product-list.component page where I created the OnDelete method to be able to delete the single product.
The method is correct, but I have a problem that in the table there are relations to the "CommandRighe" table that inhibit deletion.
I modified the OnDelete method with try catch to be able to intercept the error code and send an error message to the user.
It does not work and I would like to know how to handle the problem in order to send the user an error message telling him that the record cannot be deleted.
How can I do ?
thank you

NOTE: I started brand new project in ASP Core 2 framework so no migration from 1.x to 2.0 was needed.
What am i doing wrong?
To run an Entity Framework migration you need to disable the InitialiseDatabase call.
Once the migration has been created you can enable it again.
I know it's not your answer but if anyone else runs into this I found another cause. I was adding the ConfigurationDbContext to the DI container before adding it to IdentityServer and that caused the migration to not get added via IdentityServer.
Startup:
var migrationsAssembly = typeof(Startup).GetTypeInfo().Assembly.GetName().Name;
var optionsContextBuilder = new Action<DbContextOptionsBuilder>(options => options.UseSqlServer(authConnectionString, sql => sql.MigrationsAssembly(migrationsAssembly)));
// This caused my migration to not get run
services.AddDbContext<ConfigurationDbContext>(options => options.UseSqlServer(authConnectionString));
services.AddSingleton(sp => new ConfigurationStoreOptions { ConfigureDbContext = optionsContextBuilder });
// The above two lines needed to be moved below these lines
identityServerBuilder
.AddSigningCredential(certificate)
.AddConfigurationStore(options => options.ConfigureDbContext = optionsContextBuilder)
.AddOperationalStore(options => options.ConfigureDbContext = optionsContextBuilder)
Hope this helps someone else!

I think i need to convert the text in the txtPaginas.text to an int right?

I am getting this error while trying to execute the attached code. Please help. I am getting values as list array in controller method successfully but when I try to read data from sql database I am getting error.

string dogCsv = string.Join(",", firstField.ToArray());
Console.WriteLine(dogCsv);

Since you are using inline SQL, every value within dogCSV string that's comma separated needs a single quote around it. For instance, if dogCSV has "account2,someotheraccount", this won't work it needs to be "'account2','someotheraccount'".
If you don't that definitely would be the issue.
EDIT: Build dogCSV like this:
string dogCsv = string.Join(",", firstField.Select(i => "'" + i + "'"));
The way it's built now will not put quotes around it.
