Method overloads

I have a method which I want overload (I hope that is the right term to use here).

However I want to overload the method with the same number of parameters.

For example

public bool AEvalidation(string PNo, DateTime DatePatJoined)

public bool AEvalidation(string PNo, int HouseNo)

This returned an error because I had the same number of overloads in my method.

Therefore I had no choice but to use

public bool AEvalidation(string PNo, DateTime DatePatJoined, bool CheckDigit)

This work around solved the porblem. But is there a better approach which I should have taken?

There must be something else with your code. Perhaps the error was about calling the method? Because your overloads are valid: when the signature of the parameters is different, it is good. As an example, consider:

public void testMe(bool value) {}
public void testMe(string value) {}
public void testMe(Uri value) {}

etc. The shown lines of your code seem correct. Can you show the exact error message your got with the exact line?

What about this

public bool AEvalidation(string PNo, DateTime DatePatJoined){}

public bool AEvalidation(string PNo, DateTime DatePatLeft){}

How would one get arround the above code

You cannot get around that code, because both are equal. There's no way the compiler can choose between the two based on the signature. How would you?
