Microsoft.JSInterop Namespace
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Contains infrastructure for making method calls between .NET and JavaScript in Blazor applications.
Classes
| DotNetObjectReference |
Provides convenience methods to produce a DotNetObjectReference<TValue>. |
| DotNetObjectReference<TValue> |
Wraps a JS interop argument, indicating that the value should not be serialized as JSON but instead should be passed as a reference. To avoid leaking memory, the reference must later be disposed by JS code or by .NET code. |
| DotNetStreamReference |
Represents the reference to a .NET stream sent to JavaScript. |
| JSDisconnectedException |
Represents errors that occur during an interop call from .NET to JavaScript when the JavaScript runtime becomes disconnected. |
| JSException |
Represents errors that occur during an interop call from .NET to JavaScript. |
| JSInProcessObjectReferenceExtensions |
Extension methods for IJSInProcessObjectReference. |
| JSInProcessRuntime |
Abstract base class for an in-process JavaScript runtime. |
| JSInProcessRuntimeExtensions |
Extensions for IJSInProcessRuntime. |
| JSInvokableAttribute |
Identifies a .NET method as allowing invocation from JavaScript code. Any method marked with this attribute may receive arbitrary parameter values from untrusted callers. All inputs should be validated carefully. |
| JSObjectReferenceExtensions |
Extensions for IJSObjectReference. |
| JSRuntime |
Abstract base class for a JavaScript runtime. |
| JSRuntimeExtensions |
Extensions for IJSRuntime. |
Interfaces
| IJSInProcessObjectReference |
Represents a reference to a JavaScript object whose functions can be invoked synchronously. |
| IJSInProcessRuntime |
Represents an instance of a JavaScript runtime to which calls may be dispatched. |
| IJSObjectReference |
Represents a reference to a JavaScript object. |
| IJSRuntime |
Represents an instance of a JavaScript runtime to which calls may be dispatched. |
| IJSStreamReference |
Represents a reference to JavaScript data to be consumed through a Stream. |
| IJSUnmarshalledObjectReference |
Represents a reference to a JavaScript object whose functions can be invoked synchronously without JSON marshalling. |
| IJSUnmarshalledRuntime |
Represents an instance of a JavaScript runtime to which calls may be dispatched without JSON marshalling. Not all JavaScript runtimes support this capability. Currently it is only supported on WebAssembly and for security reasons, will never be supported for .NET code that runs on the server. This is an advanced mechanism that should only be used in performance-critical scenarios. |
Enums
| JSCallResultType |
Describes the type of result expected from a JS interop call. |
