How to accommodate specflow step definition to accept deferent number of parameters from specflow feature file with one method

Hi I have below Specflow feature files

First scenario

 Scenario outline:
    Given Add two numbers <num1> <num2> <num3>
    Then divide by <num4>
    Examples:
    |TestCase|num1|num2|num3|num4|
    |Add     |1   |2   |3   |4   |

Second Scenario:

 Scenario outline:
    Given Add two numbers <num1> <num2>
    Then divide by <num4>
    Examples:
    |TestCase|num1|num2|num4|
    |Add     |1   |2   |4   |

below is the code which I want in Step definition method

[Given(@"Add two numbers (.*) (.*) (.*)")]

[Given(@"Add two numbers (.*) (.*)")] 

public void Testtheconditionwith(string a, string b, string c = null)

{

}

this is not working. I don't want to write different methods with different parameters. Is there any way to achieve this?

Thanks.

SpecFlow doesn't support optional parameters in the step definition methods. You have to write two methods, but you can simply call one from the other.

[Given(@"Add two numbers (.*) (.*) (.*)")]
public void Testtheconditionwith(string a, string b, string c)
{

}

[Given(@"Add two numbers (.*) (.*)")] 
public void Testtheconditionwith(string a, string b)
{
    Testtheconditionwith(a,b,null)
}

Better would be to use the Driver pattern. More about it at: https://docs.specflow.org/projects/specflow/en/latest/Guides/DriverPattern.html
