How to clear the object reference is required error?
the script which i am using is coming up with the error that an object reference is required though i am trying to eliminating it by making it static but it isn't working out. can anyone please help me out?
do anyswer quickly because i have to finish up this project and move on.
the image shows my script which is having the error object reference is required. can anyone help me clear that error please?
As indicated error message, UDPCom.sendLTDimples is non static function. So you will have to create a new object of class UDPCom and then using that object call the function.
UDPCom obj = new UDPCom();
Obj.sendLTDimples();

I 've a doubt that researching I couldn't solve.
I want to pass a parameter using a var type to this method:
public static List<T[]> sortRequests<T>(List<T> _requests)
{
return null;
}
And I am calliinf the method here:
//Note: Thats code corresponds from an HttpRest service.
var _requests = await _requestService.Search(new SearchRequestSpecificationMapper().Map(searchRequestsViewModel));
var requests = sortRequests(_requests);
So VS 2015 is reporting about an error when I call the sortRequest() method.
Can anybody help me please?
Thank you very much in advance.
_requests is (presumably) not a List<T>.
You might be able to make it into a List<T> by caling ToList:
var requests = sortRequests(_requests.ToList());
However, I can't be certain without knowing more about your code, especially what the Search and Map functions do.
NOTE
Please be aware that there is no such thing as a var type in C#. var is just a bit of syntactic sugar that means "This variable has the type of whatever I assign to it when I declare it" - it's no different to just declaring it as the correct type.

I have a database field called "PIECE" which datatype is NUMERIC(11,0),
I must convert this field to a long-datatype.
This without any luck or succes, I'll keep getting the same error:
Wrong conversion...
I tried the next things:
(long)PIECE
long.Parse(PIECE.ToString().Trim())
But I'm still having the wrong conversion message,
is here someone who can help me?
This will do it:
var result = Convert.ToInt64(PIECE);

When I tries to insert data to sqlite in window store app it gives unexpected exception in SQLite.cs file. My code looks like:-
SQLiteConnection con = new SQLiteConnection(Path.Combine(ApplicationData.Current.LocalFolder.Path, "Fav.db"));
favorities addData = new favorities();
addData.Name = Title.Text;
addData.desciption = desciption.Text;
con.Insert(addData);`
and when I click on button on which these operation are being performed run time exception arises which looks like:-
in fact this SQLite.cs file is an API which I downloaded from "Manage Nuget Package" please help me out.
Thanks & Regards,
The table doesn't exist in the database.
Use this after you create the extension:
con.CreateTable<favorities>();
The creation of the connection would be better in a using statement too.

Found this csv parser: https://github.com/bytefish/TinyCsvParser
Following his example but I even added one int property.
By setting a negative value to that int, it gave me one unvalid row.
Couldn't find any solution for this simple? problem.
The type converter was using the wrong NumberStyle as default. I have fixed the problem and added a Test case to the project: https://github.com/bytefish/TinyCsvParser/issues/2.
You could also instantiate a custom converter with the right NumberStyle (see WithCustomConverter, Example), but I suggest simply updating to the latest version (0.6), which is also updated in NuGet.

//
string productName;
byte& local1 = (byte&) productName;
//
What is this byte&?
I really don't understand. I got code from my friend but I don't understand what this line wants to tell? Because it gives error or redline in my VS2012. Can anyone explain?
It's making local1 a reference byte type, but that's probably coming from some IL decompilation and not valid C# syntax. That result code will more likely happen if you decompile a IL function with a ref string parameter.
You can't compile that code using a C# compiler. There are many things that are legal in IL but there's no C# equivalent syntax, and that's usually the way it's decompiled back (which doesn't make it compilable) in a best-effort to make it look like C#
It is invalid. The closest syntax is byte? - which adds null support to byte.
