TextWriter.WriteLineAsync Method

Definition

Asynchronously writes data to the text stream, followed by a line terminator.

Overloads

WriteLineAsync(ReadOnlyMemory<Char>, CancellationToken)

Asynchronously writes the text representation of a character memory region to the text stream, followed by a line terminator.

WriteLineAsync(String)

Asynchronously writes a string to the text stream, followed by a line terminator.

WriteLineAsync(Char[])

Asynchronously writes an array of characters to the text stream, followed by a line terminator.

WriteLineAsync(StringBuilder, CancellationToken)

Asynchronously writes the text representation of a string builder to the text stream, followed by a line terminator.

WriteLineAsync()

Asynchronously writes a line terminator to the text stream.

WriteLineAsync(Char)

Asynchronously writes a character to the text stream, followed by a line terminator.

WriteLineAsync(Char[], Int32, Int32)

Asynchronously writes a subarray of characters to the text stream, followed by a line terminator.

Remarks

The TextWriter class is an abstract class. Therefore, you do not instantiate it in your code. For an example of using the WriteLineAsync method, see the StreamWriter.WriteLineAsync method.

WriteLineAsync(ReadOnlyMemory<Char>, CancellationToken)

Asynchronously writes the text representation of a character memory region to the text stream, followed by a line terminator.

public virtual System.Threading.Tasks.Task WriteLineAsync (ReadOnlyMemory<char> buffer, System.Threading.CancellationToken cancellationToken = null);
abstract member WriteLineAsync : ReadOnlyMemory<char> * System.Threading.CancellationToken -> System.Threading.Tasks.Task
override this.WriteLineAsync : ReadOnlyMemory<char> * System.Threading.CancellationToken -> System.Threading.Tasks.Task

Parameters

buffer
ReadOnlyMemory<Char>

The character memory region to write to the text stream.

cancellationToken
CancellationToken

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

Returns

A task that represents the asynchronous write operation.

Remarks

The line terminator is defined by the CoreNewLine field.

WriteLineAsync(String)

Asynchronously writes a string to the text stream, followed by a line terminator.

public:
 virtual System::Threading::Tasks::Task ^ WriteLineAsync(System::String ^ value);
[System.Runtime.InteropServices.ComVisible(false)]
public virtual System.Threading.Tasks.Task WriteLineAsync (string value);
abstract member WriteLineAsync : string -> System.Threading.Tasks.Task
override this.WriteLineAsync : string -> System.Threading.Tasks.Task
Public Overridable Function WriteLineAsync (value As String) As Task

Parameters

value
String

The string to write. If the value is null, only a line terminator is written.

Returns

A task that represents the asynchronous write operation.

Attributes

Exceptions

The text writer is disposed.

The text writer is currently in use by a previous write operation.

Remarks

The line terminator is defined by the CoreNewLine field.

The TextWriter class is an abstract class. Therefore, you do not instantiate it in your code. For an example of using the WriteLineAsync method, see the StreamWriter.WriteLineAsync method.
