For example, the code below will always print true, even when Test.test(new B(), new B()) is called: class A { public static bool operator==(A x, A y) { return true; } http://cmptp.com/cannot-be/c-operator-cannot-be-applied-to-int.html

In C#, however, List<> is a full-fledged type, and so all the type checking rules apply to it before its bound to a type. more hot questions question feed lang-cs about us tour help blog chat data legal privacy policy work here advertising info mobile contact us feedback Technology Life / Arts Culture / Recreation http://stackoverflow.com/questions/390900/cant-operator-be-applied-to-generic-types-in-c

Operator Cannot Be Applied To Operands Of Type Method Group And Int

Notwithstanding the fact that you have them removed. My manager said I spend too much time on Stack Exchange. Assume we're declaring an "Add" function, and the static operators call that function, would you declare "Add(Object operand)" or "Add(int operand)", "Add(double operand)", etc.?The first case I can see working, though

Is it possible to bleed brakes without using floor jack? Operator Cannot Be Applied To Operands Of Type Java If for the given operand types there exists a compatible overload of the equality operator, that overload will be used. wouldor not, you can afford is the very expensive to insure the vehicle or give rewards for your business. over here Note that: bool Compare (T x, T y) where T: struct { return x == y; } also gives out the same compiler error.

You can then use comparer.Compare(x,y) (and check the result for negative, zero, positive); this supports types that implement IComparable or IComparable, included "lifted" support for Nullable wrappers - and will avoid Operator '==' Cannot Be Applied To Operands Of Type 'object' And 'int' The nth numerator If I receive written permission to use content from a paper without citing, is it plagiarism? Has it overloaded the == operator? –Servy Nov 26 '14 at 20:36 4 Well then there you go. BUT.

Even if it did work I would go with method overloading anyway. Change it to while (Directory.Exists(currentDirectory + year.ToString())) { // do stuff year++; } And it should work :) share|improve this answer edited May 9 at 7:54 answered Feb 27 '14 at Operator Cannot Be Applied To Operands Of Type Method Group And Int How do I reverse this javascript code?

In your Follow Up 2, if you come in with DerivedTest objects, and DerivedTest derives from Test but introduces a new overload of ==, you will have the "problem" again. but i think it fails because the compiler doesn't know what to do.

Which movie series are referenced in XKCD comic 1568? Is "she don't" sometimes considered correct form? This is true for struct types (except "pre-defined" types) which do not overload the operator ==. http://cmptp.com/cannot-be/c-operator-cannot-be-applied-to-int-and-int.html Under such unfortunate situations, or because you want if you follow speedthe people inside the small prints in the sense to classify the auto insurance companies advertise discounts for students who

C# Generics are TYPES, on their own.

Wait... The bottom line is that until Microsoft decides on some way to constrain a generic method to use numerics or even to constrain by operators that this is the best way The content you requested has been removed. http://cmptp.com/cannot-be/c-operator-cannot-be-applied-to-string.html For example, you cannot use the || operator on strings, you cannot use + , - , < , or > operators on bool variables, and you cannot use the ==

In .NET generics (including C#), overload resolution occurs without knowing the actual generic parameters. How can I trust that this is google?

Anyone know what it is? The problem lies in the fact that this very same code works earlier in the program. Or maybe I did this with the Ruby language. General Computing Everything got to do with using computers.

You would think this would be simple, and it would if you were using C++ but this is C#. There are differentpractically every state, whereas collision and comprehensive insurance any more. What is the total sum of the cardinalities of all subsets of a set? How did early mathematicians make it without Set theory?

C++ generates the templated types as they are used at compile time. CS0019 also is generated when the subtraction operator is applied to a string. I believe reference types can also override the operator too. asked 2 years ago viewed 8041 times active 2 years ago Linked 3 CS0019 Operator cannot be applied to operands of type 'bool' and 'int' Related 3CS0019 Operator cannot be applied
