Entry is throwing errors

This question already has an answer here:

Error message: Cannot convert type 'string' to 'string[]' 4 answers

The other answers are correct (the compiler does not let you pass a string as an argument to a method expecting a string array), but an alternative approach is to change the method signature of your Main method like so:

static void Main(params string[] arg)

The params keyword allows arguments to be passed in separately instead of an array. Thus, the following calls would be equivalent:

Main("month");
Main(new string[] {"month"});

Incidentally -- while it is legal, it is not common to call the Main method (your program's entry point) from your own program. Depending on your requirements, you may want to consider a new method that has only a single string as an argument, eg:

public static void MyMethod(string s)
{
      // your code
}

// in your Main method
MyMethod("month");

String is one String. String[] is an array of Strings.

Try this:

String[] parameters = new String[] {"month"};
Main(parameters);
