Ignore code analysis rules in Visual Studio

Question

How do I ignore a specific VS code analysis rule (say CA1305 : Microsoft.Globalization) within a:

• Method?
• Class?
• Namespace?

(Assuming these options are all possible.)

Answer 1

You can use the SupressMessage attribute like this:-

[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2233:OperationsShouldNotOverflow", MessageId = "newValue+1", Justification = "The reason I think its acceptable in this case")]
void SomeMethod()
{
   // Some code that would normal cause this Code Analysis message
}

On a method, property, type etc.

Answer 2

Use #pragma warning(suppress: Cxxxx)

You can put the pragma at the appropriate scope in the source file (i.e. class, method)
