使用通用返回类型不工作的重载静态方法

Question

I have the following 2 overloaded staic methods defined in my static Class:

private static Dictionary<int, PartitionDefinition> GetNewPartitionDefinitions (string  measureGroup, int rangeThreshold)
    {
         do something;
}
private static Dictionary<int, PartitionDefinition> GetNewPartitionDefinitions(DateRange startDateRange)
{
do something else;
}

The behavior I'm getting is which ever method is listed first in the code is the one that is recognized during design-time. The subsequent method name in the chain gets greyed out and I if I hover over it I receive the message 'Method is never used'.

I have also noted that if I attempt to call the method, intellisense only detects the first one appearing in the code, like the other doesn't exist.

Researching the problem I "believe" I can eliminate the condition of Type Erasure as being the issue but I'm not 100% absolutely certain of this.

I do know that the following code would constitute valid for Type Erasure using Generics:

public class A {
 public static MethodOne  (List<String> param) {}
 public static MethodOne  (Dictionary<String,String> param) {}
}

But in this case, the generics are being passed as parameters so I can see how this would cause a problem. In my instance, only the return types are identical Generic types but one would think that having the same method name and clearly having different non-generic parameter types and number should work.

Could someone please shed a bit of light on this? I have looked at similar article postings here, but none of them seem to describe the precise problem I am seeing.

I am not new to programming but I don't claim to know everything and this one is a first for me.

Answer 1

The Message you receive might be because you are not using the methode in your code, the issue to overload static methods is actually allowed and shouldnt be a problem or cause any compiler error, you may want to check your configuration for the warnings and hints in VS.

I just tested it using this code:

public static class TestClass
    {
        public static string stat(string measureGroup, int rangeThreshold)
        {
            return "st1";
        }

        public static string stat(int startDateRange)
        {
            return "st2";
        }

        private testmethode()
        {
           // string h = TestClass.stat(.... at this point i get both variants offered)
        }

    }
