C#: how to get first char of a string?

Can the first `char` of a string be retrieved by doing the following?

MyString.ToCharArray[0]

Just `MyString[0]`. This uses the [String.Chars][1] indexer.

`Mystring[0]` should be enough

I think you are looking for this `MyString.ToCharArray()[0]`

:)

But you can use `MyString[0]` too.

The difference between `MyString[0]` and `MyString.ToCharArray()[0]` is that the former treats the string as a read-only array, while `ToCharArray()` creates a new array. The former will be quicker (along with easier) for almost anything where it will work, but `ToCharArray` can be necessary if you have a method that needs to accept an array, or if you want to change the array.

If the string isn't known to be non-null and non-empty you could do:

string.IsNullOrEmpty(MyString) ? (char?)null : MyString[0]

which returns a `char?` of either null or the first character in the string, as appropriate.

Or you can do this:

MyString[0];
