| FromJsonStreamAsync(Stream, CancellationToken) |
Asynchronously deserializes a JSON stream into a CoreActivity object. |
| FromJsonStreamAsync<T>(Stream, CancellationToken) |
Asynchronously deserializes a JSON value from the specified stream into an instance of type T. |

FromJsonStreamAsync(Stream, CancellationToken)
Asynchronously deserializes a JSON stream into a CoreActivity object.
public static System.Threading.Tasks.ValueTask<Microsoft.Teams.Core.Schema.CoreActivity?> FromJsonStreamAsync(System.IO.Stream stream, System.Threading.CancellationToken cancellationToken = default);static member FromJsonStreamAsync : System.IO.Stream * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<Microsoft.Teams.Core.Schema.CoreActivity>Public Shared Function FromJsonStreamAsync (stream As Stream, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of CoreActivity)Parameters
- stream
- Stream
The stream containing JSON data to deserialize.
- cancellationToken
- CancellationToken
A cancellation token to cancel the operation.
Returns
A task that represents the asynchronous operation. The task result contains the deserialized CoreActivity instance, or null if deserialization fails.
Applies to
FromJsonStreamAsync<T>(Stream, CancellationToken)
Asynchronously deserializes a JSON value from the specified stream into an instance of type T.
public static System.Threading.Tasks.ValueTask<T?> FromJsonStreamAsync<T>(System.IO.Stream stream, System.Threading.CancellationToken cancellationToken = default) where T : Microsoft.Teams.Core.Schema.CoreActivity;static member FromJsonStreamAsync : System.IO.Stream * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<'T (requires 'T :> Microsoft.Teams.Core.Schema.CoreActivity)> (requires 'T :> Microsoft.Teams.Core.Schema.CoreActivity)Public Shared Function FromJsonStreamAsync(Of T As CoreActivity) (stream As Stream, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of T)Type Parameters
- T
The type of the object to deserialize. Must derive from CoreActivity.
Parameters
- stream
- Stream
The stream containing the JSON data to deserialize. The stream must be readable and positioned at the start of the JSON content.
- cancellationToken
- CancellationToken
A cancellation token that can be used to cancel the asynchronous operation.
Returns
A ValueTask that represents the asynchronous operation. The result contains an instance of type T if deserialization is successful; otherwise, null.
Remarks
The caller is responsible for managing the lifetime of the provided stream. The method uses default JSON serialization options.
Applies to
FromJsonStreamAsync<T>(Stream, JsonTypeInfo<T>, CancellationToken)
Asynchronously deserializes a JSON stream into an instance of type T using the specified JsonTypeInfo<T> for source-generated serialization.
public static System.Threading.Tasks.ValueTask<T?> FromJsonStreamAsync<T>(System.IO.Stream stream, System.Text.Json.Serialization.Metadata.JsonTypeInfo<T> jsonTypeInfo, System.Threading.CancellationToken cancellationToken = default) where T : Microsoft.Teams.Core.Schema.CoreActivity;static member FromJsonStreamAsync : System.IO.Stream * System.Text.Json.Serialization.Metadata.JsonTypeInfo<'T (requires 'T :> Microsoft.Teams.Core.Schema.CoreActivity)> * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<'T (requires 'T :> Microsoft.Teams.Core.Schema.CoreActivity)> (requires 'T :> Microsoft.Teams.Core.Schema.CoreActivity)Public Shared Function FromJsonStreamAsync(Of T As CoreActivity) (stream As Stream, jsonTypeInfo As JsonTypeInfo(Of T), Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of T)Type Parameters
- T
The type of the activity to deserialize. Must inherit from CoreActivity.
Parameters
- stream
- Stream
The stream containing JSON data to deserialize.
- jsonTypeInfo
- JsonTypeInfo<T>
The JSON type info that provides deserialization metadata for type T.
- cancellationToken
- CancellationToken
A cancellation token to cancel the operation.
Returns
A ValueTask<TResult> representing the asynchronous operation. The result contains the deserialized activity, or null if deserialization fails.
