Question

For logging purposes, I would like to call the .ToString() method of every object on an object[] array. How can I do this in the simplest way?

Say I have :

   myArray = new Object[]{"astring",1, Customer}

   Log(????);

How can I pass a string such as its value is equal to:

"astring".ToString()+1.ToString()+Customer.ToString()

Or better, with comma between each value.

Answer 1

Like this:

Log(String.Join(", ", myArray.Select(o => o.ToString()).ToArray()));

---

Update:

From framework 4 the Join method can also take an IEnumerable<string>, so you don’t need the ToArray:

Log(String.Join(", ", myArray.Select(o => o.ToString())));
