VB.NET to English - What is this line of code supposed to do?

Hi please could some interpret the following line of code into English?

"foo".TrimEnd(New Char(0  - 1) {})

I know what TrimEnd will do but not the Char bit.

I think this is a NOOP because TrimEnd() is passed an empty array. This code will check if "o" (last character of "foo") is in the empty array, which it is not, and return "foo".

The code you posted is quite meaningless in the context posted so was this manipulated from some code you found or a made up example?

To answer your question:

  • TrimEnd removes characters from the end of a string
  • New Char(x) creates an array of characters to be removed, x specifies the size of the array
  • 0-1 specifies the upper bound of the array is -1 - this doesn't make much sense as the array starts at 0 and ends at -1
  • {} initialises the character array
