| Overload | Description |
|---|---|
| Single(IEntityScalarQuery) | Returns the only element of a sequence, and throws an exception if there is not exactly one element in the sequence. |
| Single(IEntityScalarQuery,CancellationToken) | Returns the only element of a sequence, and throws an exception if there is not exactly one element in the sequence. Pass in a System.Threading.CancellationToken to cancel operation. |
| Single<TSource>(IEntityScalarQuery<TSource>) | Returns the only element of a sequence, and throws an exception if there is not exactly one element in the sequence. |
| Single<TSource>(IEntityScalarQuery<TSource>,CancellationToken) | Returns the only element of a sequence, and throws an exception if there is not exactly one element in the sequence. Pass in a System.Threading.CancellationToken to cancel operation. |
| Single(IEntityScalarQuery,IPredicateDescription) | Returns the only element of a sequence that satisfies a specified condition, and throws an exception if more than one such element exists. |
| Single(IEntityScalarQuery,IPredicateDescription,CancellationToken) | Returns the only element of a sequence that satisfies a specified condition, and throws an exception if more than one such element exists. Pass in a System.Threading.CancellationToken to cancel operation. |
| Single<TSource>(IEntityScalarQuery<TSource>,Expression<Func<TSource,Boolean>>) | Returns the only element of a sequence that satisfies a specified condition, and throws an exception if more than one such element exists. |
| Single<TSource>(IEntityScalarQuery<TSource>,Expression<Func<TSource,Boolean>>,CancellationToken) | Returns the only element of a sequence that satisfies a specified condition, and throws an exception if more than one such element exists. Pass in a System.Threading.CancellationToken to cancel operation. |
