System.Diagnostics.CodeAnalysis Namespace

Contains classes for interaction with code analysis tools. These tools are used to analyze code for conformance to coding conventions such as naming or security rules.

Classes

AllowNullAttribute

Specifies that null is allowed as an input even if the corresponding type disallows it.

ConstantExpectedAttribute

Indicates that the specified method parameter expects a constant.

DisallowNullAttribute

Specifies that null is disallowed as an input even if the corresponding type allows it.

DoesNotReturnAttribute

Specifies that a method will never return under any circumstance.

DoesNotReturnIfAttribute

Specifies that the method will not return if the associated Boolean parameter is passed the specified value.

DynamicallyAccessedMembersAttribute

Indicates that certain members on a specified Type are accessed dynamically, for example, through System.Reflection.

DynamicDependencyAttribute

States a dependency that one member has on another.

ExcludeFromCodeCoverageAttribute

Specifies that the attributed code should be excluded from code coverage information.

ExperimentalAttribute

Indicates that an API is experimental and it may change in the future.

FeatureGuardAttribute

Indicates that the specified public static Boolean read-only property guards access to the specified feature.

FeatureSwitchDefinitionAttribute

Indicates that the specified public static Boolean read-only property corresponds to the feature switch specified by name.

MaybeNullAttribute

Specifies that an output may be null even if the corresponding type disallows it.

MaybeNullWhenAttribute

Specifies that when a method returns ReturnValue, the parameter may be null even if the corresponding type disallows it.

MemberNotNullAttribute

Specifies that the method or property will ensure that the listed field and property members have values that aren't null.

MemberNotNullWhenAttribute

Specifies that the method or property will ensure that the listed field and property members have non-null values when returning with the specified return value condition.

NotNullAttribute

Specifies that an output is not null even if the corresponding type allows it. Specifies that an input argument was not null when the call returns.

NotNullIfNotNullAttribute

Specifies that the output will be non-null if the named parameter is non-null.

NotNullWhenAttribute

Specifies that when a method returns ReturnValue, the parameter will not be null even if the corresponding type allows it.

RequiresAssemblyFilesAttribute

Indicates that the specified member requires assembly files to be on disk.

RequiresDynamicCodeAttribute

Indicates that the specified method requires the ability to generate new code at runtime, for example through System.Reflection.

RequiresUnreferencedCodeAttribute

Indicates that the specified method requires dynamic access to code that is not referenced statically, for example, through System.Reflection.

SetsRequiredMembersAttribute

Specifies that this constructor sets all required members for the current type, and callers do not need to set any required members themselves.

StringSyntaxAttribute

Specifies the syntax used in a string.

SuppressMessageAttribute

Suppresses reporting of a specific code analysis rule violation, allowing multiple suppressions on a single code artifact. Does not apply to compiler diagnostics.

UnconditionalSuppressMessageAttribute

Suppresses reporting of a specific rule violation, allowing multiple suppressions on a single code artifact.

UnscopedRefAttribute

Used to indicate a byref escapes and is not scoped.

Enums

DynamicallyAccessedMemberTypes

Specifies the types of members that are dynamically accessed. This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.
