case.This rule has no associated code-style options.
enum E
{

}
class C
{
// Code with violations
int M(E e)
{
// IDE0010: Add missing cases
switch (e)
{
case E.A:
return 0;
}
return -1;
}
// Fixed code
int M(E e)
{
switch (e)
{
case E.A:
return 0;
case E.B:
return 1;
default:
return -1;
}
}
}
If you want to suppress only a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.
#pragma warning disable IDE0010
// The code that's violating the rule is on this line.
#pragma warning restore IDE0010

in the configuration file.
