SuppressMessageAttribute.SuppressMessageAttribute Constructor

Initializes a new instance of the SuppressMessageAttribute class, specifying the category of the static analysis tool and the identifier for an analysis rule.

Namespace: System.Diagnostics.CodeAnalysis
Assembly: mscorlib (in mscorlib.dll)

public SuppressMessageAttribute (
	string category,
	string checkId
)
public SuppressMessageAttribute (
	String category, 
	String checkId
)
public function SuppressMessageAttribute (
	category : String, 
	checkId : String
)
Not applicable.

Parameters

category

The category for the attribute.

checkId

The identifier of the analysis tool rule the attribute applies to.

The category parameter value is specific to the analysis tool and categorizes the rule identified by the checkId parameter. The two parameters concatenated together form a unique identifier for the rule.

NoteNote:

The preprocessor symbol "CODE_ANALYSIS" must be defined for this attribute to be effective. The absence of the preprocessor symbol results in the attribute not being applied.

The following code example shows the use of the SuppressMessageAttribute attribute to suppress warnings for the Microsoft.Performance category and the CA1801 and CA1804 check identifiers. This code example is part of a larger example provided for the SuppressMessageAttribute class.

[SuppressMessage("Microsoft.Performance", "CA1801:ReviewUnusedParameters", MessageId = "isChecked")]
[SuppressMessage("Microsoft.Performance", "CA1804:RemoveUnusedLocals", MessageId = "fileIdentifier")]
static void FileNode(string name, bool isChecked)
{
    string fileIdentifier = name;
    string fileName = name;
    string version = String.Empty;
}
