System.Runtime.InteropServices.JavaScript Namespace

Contains JSImportAttribute and JSExportAttribute, which can be used to interop with JavaScript when running in the browser or other WASM architectures.

Classes

JSException	Represents an exception initiated from the JavaScript interop code.
JSExportAttribute	Indicates that a source generator should export the attributed method to JavaScript and create thunks necessary to marshal its arguments and any return value or thrown exception.
JSFunctionBinding	Represents a bound imported or exported JavaScript function and contains information necessary to invoke it. This API supports JSImport infrastructure and is not intended to be used directly from your code.
JSHost	Represents the JavaScript host environment where the .NET runtime is currently operating.
JSImportAttribute	Indicates that the JSImport source generator should create a managed wrapper to invoke a specific imported JavaScript function and marshal its arguments, return values, and exceptions.
JSMarshalAsAttribute<T>	Specifies the JavaScript type associated with a managed argument or return value. The JSImport generator will use this information to marshal data between the JavaScript and managed environments.
JSMarshalerType	Represents type metadata about the marshaller that are necessary for marshalling function arguments. This API is used by the JSImport code generator and should not be used by developers in source code.
JSObject	Represents a reference to an object in the JavaScript host environment and enables interaction with it as a proxy.
JSType	Used as the generic argument for JSMarshalAsAttribute<T> to express the expected JavaScript type, which should be the source or result of argument marshalling.
JSType.Any	Dynamically selects the most appropriate JavaScript or managed type for each argument value at run time.
JSType.Array<T>	Marshals as a copy of the JavaScript Array or TypedArray type.
JSType.BigInt	Marshal as JavaScript BigInt type.
JSType.Boolean	Marshal as JavaScript Boolean type.
JSType.Date	Marshal as JavaScript Date type.
JSType.Discard	Suppresses marshalling of the JavaScript function's return value and discards it.
JSType.Error	Marshals as the JavaScript Error type.
JSType.Function	Marshals as the JavaScript Function type.
JSType.Function<T>	Marshals as the JavaScript Function type.
JSType.Function<T1,T2>	Marshals as the JavaScript Function type.
JSType.Function<T1,T2,T3>	Marshals as the JavaScript Function type.
JSType.Function<T1,T2,T3,T4>	Marshals as the JavaScript Function type.
JSType.MemoryView	Marshals a managed Span or ArraySegment as a JavaScript wrapper object that provides access to the managed memory.
JSType.Number	Marshal as JavaScript Number type.
JSType.Object	Marshal as JavaScript Object type.
JSType.Promise<T>	Marshal as JavaScript Promise type.
JSType.String	Marshal as JavaScript String type.
JSType.Void	Asserts that a JavaScript function should have no return value.

Structs

JSMarshalerArgument

Contains the storage and type information for an argument or return value on the native stack. This API supports JSImport infrastructure and is not intended to be used directly from your code.

Delegates

JSMarshalerArgument.ArgumentToJSCallback<T>	Assists in marshalling of Task results and Function arguments. This API is used by JSImport code generator and should not be used by developers in source code.
JSMarshalerArgument.ArgumentToManagedCallback<T>	Assists in marshalling of Task results and Function arguments. This API is used by JSImport code generator and should not be used by developers in source code.
