Definition

Overloads

ExistsAsync()

Initiates an asynchronous operation to determine whether a table exists.

ExistsAsync(CancellationToken)

Initiates an asynchronous operation to determine whether a table exists.

ExistsAsync(TableRequestOptions, OperationContext)

Initiates an asynchronous operation to determine whether a table exists.

ExistsAsync(TableRequestOptions, OperationContext, CancellationToken)

Initiates an asynchronous operation to determine whether a table exists.

ExistsAsync()

Initiates an asynchronous operation to determine whether a table exists.

public virtual System.Threading.Tasks.Task<bool> ExistsAsync ();
abstract member ExistsAsync : unit -> System.Threading.Tasks.Task<bool>
override this.ExistsAsync : unit -> System.Threading.Tasks.Task<bool>
Public Overridable Function ExistsAsync () As Task(Of Boolean)

Returns

A Task<TResult> object of type bool that represents the asynchronous operation.

Applies to

ExistsAsync(CancellationToken)

Initiates an asynchronous operation to determine whether a table exists.

public virtual System.Threading.Tasks.Task<bool> ExistsAsync (System.Threading.CancellationToken cancellationToken);
abstract member ExistsAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task<bool>
override this.ExistsAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task<bool>
Public Overridable Function ExistsAsync (cancellationToken As CancellationToken) As Task(Of Boolean)

Parameters

cancellationToken
CancellationToken

A CancellationToken to observe while waiting for a task to complete.

Returns

A Task<TResult> object of type bool that represents the asynchronous operation.

Applies to

ExistsAsync(TableRequestOptions, OperationContext)

Initiates an asynchronous operation to determine whether a table exists.

public virtual System.Threading.Tasks.Task<bool> ExistsAsync (Microsoft.Azure.Cosmos.Table.TableRequestOptions requestOptions, Microsoft.Azure.Cosmos.Table.OperationContext operationContext);
abstract member ExistsAsync : Microsoft.Azure.Cosmos.Table.TableRequestOptions * Microsoft.Azure.Cosmos.Table.OperationContext -> System.Threading.Tasks.Task<bool>
override this.ExistsAsync : Microsoft.Azure.Cosmos.Table.TableRequestOptions * Microsoft.Azure.Cosmos.Table.OperationContext -> System.Threading.Tasks.Task<bool>
