I have a string in one class, I would like to get the string in my web api for the get request and add the value to my query. This is my code to get data from my Mysql database:
Web api
// GET: api/Blog
[HttpGet]
public List<BlogViews> Get()
{
string sqlstring = "server=; port= ; user id =;Password=;Database=;";
MySqlConnection conn = new MySqlConnection(sqlstring);
try
{
conn.Open();
}
catch (MySqlException ex)
{
throw ex;
}
string Query = "SELECT * FROM test.blogtable where `Category` =" +;
MySqlCommand cmd = new MySqlCommand(Query, conn);
MySqlDataReader MSQLRD = cmd.ExecuteReader();
List<BlogViews> GetBlogList = new List<BlogViews>();
if (MSQLRD.HasRows)
{
while (MSQLRD.Read())
{
BlogViews BV = new BlogViews();
BV.id = (MSQLRD["id"].ToString());
BV.DisplayTopic = (MSQLRD["Topic"].ToString());
BV.DisplayMain = (MSQLRD["Summary"].ToString());
GetBlogList.Add(BV);
}
}
conn.Close();
return GetBlogList;
}
My Class
public class ItemsClass
{
public string id { get; set; }
public Entry IdEntry = new Entry{};
public Button DoneButton = new Button{};
public ItemsClass()
{
Content = new StackLayout
{
BackgroundColor = Color.FromHex("35ddcf"),
Padding = new Thickness(0, 50, 0, 10),
Children = { IdEntry,DoneButton }
};
}
private void DoneButton_Clicked(object sender, EventArgs e)
{
IdEntry.Text = id;
BlogContentsRestClient<BlogContentItemClass> restClient = new
BlogContentsRestClient<BlogContentItemClass>();
await restClient.GetAsync();
}
}
HttpRequest Class
public class BlogContentsRestClient<T>
{
private const string WebServiceUrl = "http://localhost:57645/api/BlogContents/";
public async Task<List<T>> GetAsync()
{
var httpClient = new HttpClient();
var json = await httpClient.GetStringAsync(WebServiceUrl);
var taskModels = JsonConvert.DeserializeObject<List<T>>(json);
return taskModels;
}
}
Question
In my Web api Querystring Query = "SELECT * FROM test.blogtable where 'Category' =" +;. I would like to add the value of string id in ItemsClass, so that I can get data from my Mysql database.
I don't quite get what you mean by add the value of a class to your API method. ItemsClass is an object definition and not an instance of it. However you can provide your API method a parameter so that you have:
[HttpGet]
public List<BlogViews> Get(string id)
You can now call your API passing that parameter: /api/?id={insert here the id}
Alternatively you can call it in your request's body.
[HttpGet]
public List<BlogViews> Get([FromQuery, BindRequired] string id)
EDIT:
Check if this solution fits:
1) Use the method I posted before replacing this:
public List<BlogViews> Get()
with this:
public List<BlogViews> Get(string id)
2) Edit the GetAsync() method as follow:
// Added string id as parameter
public async Task<List<T>> GetAsync(string id)
{
// webUrl now become the same as WebServiceUrl but with parameter added
string webUrl = "http://localhost:57645/api/BlogContents/?id=" + id;
var httpClient = new HttpClient();
var json = await httpClient.GetStringAsync(webUrl);
var taskModels = JsonConvert.DeserializeObject<List<T>>(json);
return taskModels;
}
3) Edit the DoneButton_Clicked this way:
private void DoneButton_Clicked(object sender, EventArgs e)
{
IdEntry.Text = id;
BlogContentsRestClient<BlogContentItemClass> restClient = new
BlogContentsRestClient<BlogContentItemClass>();
await restClient.GetAsync(id); // Here you call the Get API with the id as parameter
}
4) Finally you can edit the query inside your Get(string id) method adding the id to the end:
string Query = "SELECT * FROM test.blogtable where `Category` =" + id;

I am using the following Code
public class GetTabelRealizari : ControllerBase
{
public class Realizare
{
String user;
String denumire;
String incasari;
public Realizare(String user, String denumire, String incasari)
{
this.user = user;
this.denumire = denumire;
this.incasari = incasari;
}
public String getUser()
{
return user;
}
public void setUser(String user)
{
this.user = user;
}
public String getDenumire()
{
return denumire;
}
public void setDenumire(String denumire)
{
this.denumire = denumire;
}
public String getIncasari()
{
return incasari;
}
public void setIncasari(String incasari)
{
this.incasari = incasari;
}
}
[HttpPost]
public string Post([FromBody] string[] value)
{
//SSMS connection
string connectionString = "Data Source=DESKTOP-QKC0G7V;Initial Catalog=Restaurant_gest;Integrated Security=True";
SqlConnection connection = new SqlConnection(connectionString);
connection.Open();
List<Realizare> realizari = new List<Realizare>();
double incasari;
String incasariString;
SqlCommand command = new SqlCommand("SELECT Users.Username," +
" Tip_Nota_Plata.Denumire," +
" sum(Nota_plata.Suma) as Incasari" +
" from Users" +
" INNER JOIN Nota_plata" +
" INNER JOIN Comandas" +
" ON Nota_plata.Id_comanda = Comandas.Id" +
" ON Comandas.User_Id = Users.Id" +
" INNER JOIN Tip_Nota_Plata" +
" ON Tip_Nota_Plata.Id = Nota_plata.Id_tip_nota" +
" Group by Username, Tip_Nota_Plata.Denumire", connection);
using (SqlDataReader reader = command.ExecuteReader())
{
while (reader.Read())
{
incasari = (double)reader["Incasari"];
incasariString = incasari.ToString("#.##");
realizari.Add(new Realizare(reader["Username"].ToString(), reader["Denumire"].ToString(), incasariString));
}
}
return JsonConvert.SerializeObject(realizari);
//return "salut";
}
}
And I am receiving an empty JsonObject. Why?
[{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{}]
I keep trying to make it work and I cannot. The list has the objects, i can test it with Console.Writeline(realizari[0].getDenumire()) and it works. I can also serialize a list of strings, it just doesn`t work for objects.
Because the object has no serializable properties.
I'm going to guess you are a Java developer based on this:
String user;
public String getUser()
{
return user;
}
public void setUser(String user)
{
this.user = user;
}
C# has "properties" which, while they compile down to methods very similar to this, the syntax in C# is a bit different. All of the above code can be simplified to a property:
public String User { get; set; }
The usage then becomes simpler as well, allowing for assignments instead of calling a method:
someObject.User = someUser;
In cases where you want to add logic to your getter/setter, you can expand the "auto implemented property" above into a manual one:
private string user;
public string User
{
get { return user; }
set { user = value; }
}
The get and set syntax still tells the compiler that this is a property, but within those blocks you can write any method logic you like. (In the setter value is a keyword for the value being assigned to the property.)
I’m getting an error in VS trying to check the Return Code of a method that builds and post data via an API.
The line that is generating the error is:
if (BuildApi(MyGlobals.data5, MyGlobals.data1, FQAN, MyGlobals.data4) == MyGlobals.ReturnCode)
The error is:
Operator '==' cannot be applied to operands of type 'Task<string'>' and 'string'
My goal is to pass those parameters (data1, data5, etc) to the BuildApi() method and then post that data via an API call.
When the data is successfully posted, I should get a Return Code of 200 or a Return Code of 400 if an error occurred (according to the API developer).
The BuildApi() method should return either a 200 or 400 back to the condition statement.
Is the BuildApi() method formatted correctly to return the Return Code and if so, what’s wrong with that “if” statement?
Thanks in advance for your help!

Your BuildApi function is async so you need to await it in your code:
if (await BuildApi(MyGlobals.data5, MyGlobals.data1, FQAN, MyGlobals.data4) == MyGlobals.ReturnCode)
UPDATE:
If you can't run it async then you need the result:
if (BuildApi(MyGlobals.data5, MyGlobals.data1, FQAN, MyGlobals.data4).Result == MyGlobals.ReturnCode)
However, I would try in the first instance to make your calling method async
I am relatively new to c# and have only been a developer for a couple years. I followed this really great tutorial on how to make a library with data models and interfaces to handle retrieving and inserting data into my database. I am working on a Blazor server side application. I utilize my data access library by injecting its interface onto the razor page via a service created in the startup.cs. All of this works fantastically.
However, Now I am making class that reads delimited files and inserts the data into the database table. I would like to use the same interfaces in my data access library that I use to connect my razor pages to the back end.
Here is my class where I want to use the InsertPermit method from IpermitData to insert a record to my database table but _db is null and will give me a null reference exception when I run it. How can I get a handle on this interface so I can use it to insert data?

welcome to the community! The nice thing about .Net core is it makes the dependency injection system work very smoothly. So in your constructor for your parser, you just need to inject what you need from your data access layer. An example with your PermitData class would look like this:
public class TextFileParser
{
private IPermitData _permitData;
public TextFileParser(IPermitData permitData)
{
this._permitData= permitData;
}
// code that uses your injected service
_permitData.MethodToDoWorkEtc();
}
Notice that in the constructor you call for the interface you need as I have it written, but you can also call for a concrete class if that is how your dependency injection is set up. It then populates a backing field in your class with the injected service, and you use the backing field as the start point to do the work that needs done.
The DI framework will pick this all up when you build your app and assemble it for you, so as long as the service is registered in the Startup.cs file, you shouldn't need anything else. This method will also allow you to compose simple services together into larger more advanced services while keeping the simple parts separated for better testing and portability.
Hope this helps!
I have created the class at the bottom in c#. This class is referenced by webservices to determine user accesses, like this:
[WebMethod]
public List<FAFSA> getFAFSA(string pageID)
{
formValues fv = new formValues();
string personID = fv.personID;
List<FAFSA> lf = new List<FAFSA>();
if (fv.secBlur == "no_secBlur")
{
FAFSA f = new FAFSA();
f.fafsaCheck = "0";
lf.Add(f);
}
...
}
I'm trying to add the two variables fafsa and staff. The method getSecBlur() is returning all three values from my database for secBlur, fafsa, and staff. So how do I set up this class, so that the SecBlur method is only called once but populates all three of my variables so that they can be used in webservice calls? It will not work the way it is now because it says fafsa and staff need to be static, but if I make them static, then in the webservices it says that the members must be accessed with an instance reference.
Sorry if this isn't worded to well, but I'm new to this and still trying to learn...
public class formValues : System.Web.Services.WebService
{
public string userName = getUserName();
public string firstName = getFirstName();
public string personID = getPersonID();
public int fafsa = 0;
public int staff = 0;
public string secBlur = getSecBlur();
private static string getUserDataString(int ix)
{
string retValue = "";
if (HttpContext.Current.Request.IsAuthenticated)
{
HttpCookie authCookie = HttpContext.Current.Request.Cookies[FormsAuthentication.FormsCookieName];
if (authCookie != null)
{
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(authCookie.Value);
if (ticket != null)
{
string[] userData = { "" };
char[] delimiterChar = { '|' };
userData = ticket.UserData.Split(delimiterChar);
if (userData.Length > 1)
retValue = userData[ix];
else
{
FormsAuthentication.SignOut();
string redirUrl = "/DMC/loginNotFound.html";
HttpContext.Current.Response.Redirect(redirUrl, false);
}
}
}
}
return retValue;
}
private static string getUserName()
{
//This retrieves the person logged into windows/active directory
WindowsPrincipal wp = new WindowsPrincipal(WindowsIdentity.GetCurrent());
//string[] fullUsername = wp.Identity.Name.Split('\\');
string fullUsername = wp.Identity.Name;
return fullUsername;
}
private static string getFirstName()
{
string firstName = getUserDataString(1);
return firstName;
}
private static string getPersonID()
{
string personID = getUserDataString(0);
return personID;
}
private static string getSecBlur()
{
string secBlur = "no_secBlur";
string mySQL = "exec get_UserAdminStatus #personID";
string cf = System.Configuration.ConfigurationManager.ConnectionStrings["DistrictAssessmentDWConnectionString"].ConnectionString;
SqlConnection connection = new SqlConnection(cf);
SqlCommand command = new SqlCommand(mySQL, connection);
command.Parameters.AddWithValue("#personID", getUserDataString(0));
connection.Open();
SqlDataReader dr = command.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(dr);
connection.Close();
if (dt.Rows.Count > 0)
{
if (dt.Rows[0]["secBlur"].ToString() == "1")
secBlur = "secBlur";
fafsa = Convert.ToInt32(dt.Rows[0]["fafsa"]);
staff = Convert.ToInt32(dt.Rows[0]["staff"]);
}
return secBlur;
}
}
If you give any class static, public values the so called "Static" (or type) Constructor will be called to do the initialization work before any access is done: https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/static-constructors
Another common way to do initlizsation or define default values, is to use the Factory Pattern. Afaik the Graphics Class in XNA has to adapt depending if you run ona X-Box or PC, so it uses the Factory Pattern.
Of coruse with Web(anything) there is the whole issue with variable Scope, even for Statics. Much less local variables.

From the code you posted I can suggest you forgot to create an instance of CommanCall. Field Comman is reference type which is by default initialized with null. So NullReferenceException thrown when you trying to call member of null. Create an instance for Comman, for example:
public static EmpSystem.Domain.CommanCall Comman = new EmpSystem.Domain.CommanCall();
If field Comman initialized somewhere else, please, show stack trace of exception you caught.
