Asynchronously creates a new file, writes the specified lines to the file, and then closes the file.

public static System.Threading.Tasks.Task WriteAllLinesAsync (string path, System.Collections.Generic.IEnumerable<string> contents, System.Threading.CancellationToken cancellationToken = default);
static member WriteAllLinesAsync : string * seq<string> * System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Shared Function WriteAllLinesAsync (path As String, contents As IEnumerable(Of String), Optional cancellationToken As CancellationToken = Nothing) As Task

Parameters

path
String

The file to write to.

contents
IEnumerable<String>

The lines to write to the file.

cancellationToken
CancellationToken

The token to monitor for cancellation requests. The default value is None.

Returns

A task that represents the asynchronous write operation.

Exceptions

The cancellation token was canceled. This exception is stored into the returned task.

Remarks

This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by WriteAllLines(String, IEnumerable<String>).
