C# Error CS1501 – No overload for method ‘{0}’ takes {1} arguments

C# Error

CS1501 – No overload for method ‘{0}’ takes {1} arguments

Reason for the Error & Solution

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();  
            // 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.");
