Assigning string[] array into a function with params string[] [closed]

Question

I have a function void Test(int id, params string[] strs).

How would I pass an array of strings as the strs argument? When I call:

Test(1, "a, b, c"); 

It takes "strs" as a single string (not an array).

Answer 1

Actually, the params is just a syntactic sugar handled by the C# compiler, so that

this:

void Method(params string[] args) { /**/ } Method("one", "two", "three"); 

becomes this:

void Method(params string[] args) { /**/ } Method(new string[] { "one", "two", "three" }) 

Answer 2

I tested this and it works:

    private void CallTestMethod()     {         string [] strings = new string [] {"1", "2", "3"};         Test(1, strings);      }      private void Test(int id, params string[] test)     {         //Do some action with input     } 

You can call it just like this Test(1, <Some string[]>);

Edit

From MSDN website on params:

The params keyword lets you specify a method parameter that takes a variable number of arguments. You can send a comma-separated list of arguments of the type specified in the parameter declaration, or an array of arguments of the specified type. You also can send no arguments. No additional parameters are permitted after the params keyword in a method declaration, and only one params keyword is permitted in a method declaration.

So you could also call the Test method like this Test(1); without compiler errors.
