Describe the bug
CA1861 code fix creates a new field that can have the same name as a local variable
Steps To Reproduce
Original code:
class Sample
{
void A(char separator)
{
"".Split(new char[] { 'a', 'b' });
}
}After code fix:
class Sample
{
internal static readonly char[] separator = new char[] { 'a', 'b' };
void A(char separator)
{
// "separator" is the local parameter instead of the static field
"".Split(separator);
}
}Expected behavior
Generate a unique name
