switch
statement that's missing cases for one or more enum members. - A
switch
statement with a missingdefault
case.
Options
This rule has no associated code-style options.
Example
enum E
{
A,
B
}
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;
}
}
}
Suppress a warning
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
To disable the rule for a file, folder, or project, set its severity to none
in the configuration file.
[*.{cs,vb}]
dotnet_diagnostic.IDE0010.severity = none
To disable all of the code-style rules, set the severity for the category Style
to none
in the configuration file.
[*.{cs,vb}]
dotnet_analyzer_diagnostic.category-Style.severity = none
