The reference type argument to validate as non-null. The name of the parameter with which corresponds.

Throws either an or an if the specified string is or whitespace respectively.

String to be checked for or whitespace. The name of the parameter being checked. The original value of .

Attribute used to indicate a source generator should create a function for marshalling arguments instead of relying on the runtime to generate an equivalent marshalling function at run-time.

This attribute is meaningless if the source generator associated with it is not enabled. The current built-in source generator only supports C# and only supplies an implementation when applied to static, partial, non-generic methods.

Initializes a new instance of the .

Name of the library containing the import.

Gets the name of the library containing the import.

Gets or sets the name of the entry point to be called.

Gets or sets how to marshal string arguments to the method.

If this field is set to a value other than , must not be specified.

Gets or sets the used to control how string arguments to the method are marshalled.

If this field is specified, must not be specified or must be set to .

Gets or sets whether the callee sets an error (SetLastError on Windows or errno on other platforms) before returning from the attributed method.

Specifies how strings should be marshalled for generated p/invokes

Indicates the user is suppling a specific marshaller in .

Use the platform-provided UTF-8 marshaller.

Use the platform-provided UTF-16 marshaller.

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

This allows tools to understand which members are being accessed during the execution of a program. This attribute is valid on members whose type is or . When this attribute is applied to a location of type , the assumption is that the string represents a fully qualified type name. When this attribute is applied to a class, interface, or struct, the members specified can be accessed dynamically on instances returned from calling on instances of that class, interface, or struct. If the attribute is applied to a method it's treated as a special case and it implies the attribute should be applied to the "this" parameter of the method. As such the attribute should only be used on instance methods of types assignable to System.Type (or string, but no methods will use it there).

Applied to a method that will never return under any circumstance.

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

Initializes the attribute with the specified parameter value.
