AreAllNotNull(IEnumerable, String, String)
- Source:
- Assert.AreAllNotNull.cs
Tests whether all items in the specified collection are non-null and throws an exception if any element is null.
public static void AreAllNotNull(System.Collections.IEnumerable? collection, string? message = "", string collectionExpression = "");static member AreAllNotNull : System.Collections.IEnumerable * string * string -> unitPublic Shared Sub AreAllNotNull (collection As IEnumerable, Optional message As String = "", Optional collectionExpression As String = "")Parameters
- collection
- IEnumerable
The collection in which to search for null elements.
- message
- String
The message to include in the exception when collection contains
a null element. The message is shown in test results.
