AreAllDistinct(IEnumerable, String, String)

Source:: Assert.AreAllDistinct.cs

Tests whether all items in the specified collection are distinct (no two elements are equal) and throws an exception if any two elements in the collection are equal.

public static void AreAllDistinct(System.Collections.IEnumerable? collection, string? message = "", string collectionExpression = "");

static member AreAllDistinct : System.Collections.IEnumerable * string * string -> unit

Public Shared Sub AreAllDistinct (collection As IEnumerable, Optional message As String = "", Optional collectionExpression As String = "")

Parameters

collection: IEnumerable

message: String

The message to include in the exception when collection contains at least one duplicate element. The message is shown in test results.

collectionExpression: String

The syntactic expression of collection as given by the compiler via caller argument expression. Users shouldn't pass a value for this parameter.
