NotNullOrEmpty(IEnumerable, String)

Throws an exception if the specified parameter's value is null, has no elements.

public:
 static void NotNullOrEmpty(System::Collections::IEnumerable ^ values, System::String ^ parameterName);
[System.Diagnostics.DebuggerStepThrough]
public static void NotNullOrEmpty (System.Collections.IEnumerable values, string? parameterName);
[System.Diagnostics.DebuggerStepThrough]
public static void NotNullOrEmpty (System.Collections.IEnumerable values, string? parameterName = default);
[<System.Diagnostics.DebuggerStepThrough>]
static member NotNullOrEmpty : System.Collections.IEnumerable * string -> unit
Public Shared Sub NotNullOrEmpty (values As IEnumerable, parameterName As String)
Public Shared Sub NotNullOrEmpty (values As IEnumerable, Optional parameterName As String = Nothing)

Parameters

values
IEnumerable

The value of the argument.

parameterName
String

The name of the parameter to include in any thrown exception. If this argument is omitted (explicitly writing null does not qualify), the expression used in the first argument will be used as the parameter name.

Attributes

Exceptions

ArgumentException

Thrown if the tested condition is false.

Applies to
