Queryable.AsQueryable Method (IEnumerable)
.NET Framework (current version)
Converts an IEnumerable to an IQueryable.
Assembly: System.Core (in System.Core.dll)
Parameters
- source
-
Type:
System.Collections.IEnumerable
A sequence to convert.
| Exception | Condition |
|---|---|
| ArgumentException | source does not implement IEnumerable<T> for some T. |
| ArgumentNullException | source is null. |
If the type of source implements IQueryable<T>, AsQueryable(IEnumerable) returns it directly. Otherwise, it returns an IQueryable<T> that executes queries by calling the equivalent query operator methods in Enumerable instead of those in Queryable.
This method assumes that source implements IEnumerable<T> for some T. At runtime, the result is of type IQueryable<T> for the same T. This method is useful in dynamic scenarios when you do not statically know the type of T.
