QueryableAsyncExtensions

AnyAsyncEx``1

public static ValueTask<bool> AnyAsyncEx<T>(IQueryable<T> source, CancellationToken cancellationToken)

result = QueryableAsyncExtensions.AnyAsyncEx(source, cancellationToken)

Asynchronously determines whether a queryable sequence contains any elements.

source

The queryable source.

cancellationToken

Cancellation token.

戻り値: if the sequence contains any elements; otherwise, .

CountAsyncEx``1

public static ValueTask<long> CountAsyncEx<T>(IQueryable<T> source, CancellationToken cancellationToken)

result = QueryableAsyncExtensions.CountAsyncEx(source, cancellationToken)

Asynchronously counts the elements in a queryable sequence, using bulk-load when available.

source

The queryable source.

cancellationToken

Cancellation token.

戻り値: The number of elements.

FirstOrDefaultAsyncEx``1

public static ValueTask<T> FirstOrDefaultAsyncEx<T>(IQueryable<T> source, CancellationToken cancellationToken)

result = QueryableAsyncExtensions.FirstOrDefaultAsyncEx(source, cancellationToken)

Asynchronously returns the first element of a sequence, or a default value, using bulk-load when available.

source

The queryable source.

cancellationToken

Cancellation token.

戻り値: The first element, or the default value if the sequence is empty.

ToArrayAsyncEx``1

public static ValueTask<T[]> ToArrayAsyncEx<T>(IQueryable<T> source, CancellationToken cancellationToken)

result = QueryableAsyncExtensions.ToArrayAsyncEx(source, cancellationToken)

Asynchronously converts a queryable sequence to an array.

source

The queryable source.

cancellationToken

Cancellation token.

戻り値: An array containing the elements.

ToAsync``1

public static IAsyncEnumerable<T> ToAsync<T>(IQueryable<T> q)

result = QueryableAsyncExtensions.ToAsync(q)

Converts a queryable to an async enumerable, returning the existing one if already async.

q

The queryable source.

戻り値: An async enumerable over the elements.
