Code inspection: Redundant 'string.ToCharArray()' call

This inspection reports a call to ToCharArray() inside a foreach when the code can iterate over the string directly. The extra array allocation does not change the result and only adds unnecessary work.

Example

                foreach (char c in text.ToCharArray())
                {
                    Consume(c);
                }
            

                foreach (char c in text)
                {
                    Consume(c);
                }
            

Quick-fix

The quick-fix removes the ToCharArray() call and iterate over the string directly.
