Public Function MinAsync(Of TSource, TResult) (source As IQueryable(Of TSource), selector As Expression(Of Func(Of TSource, TResult))) As Task(Of TResult)Type Parameters
- TSource
The type of the elements of source.
- TResult
The type of the value returned by the function represented by selector .
Parameters
- source
- IQueryable<TSource>
An IQueryable<T> that contains the elements to determine the minimum of.
- selector
- Expression<Func<TSource,TResult>>
A projection function to apply to each element.
Returns
A task that represents the asynchronous operation. The task result contains the minimum value in the sequence.

Exceptions

.
source
doesn't implement
IDbAsyncQueryProvider
.
Remarks
Multiple active operations on the same context instance are not supported. Use 'await' to ensure that any asynchronous operations have completed before calling another method on this context.
Applies to
MinAsync<TSource,TResult>(IQueryable<TSource>, Expression<Func<TSource,TResult>>, CancellationToken)
Asynchronously invokes a projection function on each element of a sequence and returns the minimum resulting value.
