Compiler Error CS1501
Visual Studio 2012
No overload for method 'method' takes 'number' arguments
A call was made to a class method, but no definition of the method takes the specified number of arguments.
The following sample generates CS1501.
using System; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { ExampleClass ec = new ExampleClass(); ec.ExampleMethod(); ec.ExampleMethod(10); // The following line causes compiler error CS1501 because // ExampleClass does not contain an ExampleMethod that takes // two arguments. ec.ExampleMethod(10, 20); } } // ExampleClass contains two overloads for ExampleMethod. One of them // has no parameters and one has a single parameter. class ExampleClass { public void ExampleMethod() { Console.WriteLine("Zero parameters"); } public void ExampleMethod(int i) { Console.WriteLine("One integer parameter."); } //// To fix the error, you must add a method that takes two arguments. //public void ExampleMethod (int i, int j) //{ // Console.WriteLine("Two integer parameters."); //} } }
