public:
static System::Object ^ Null(System::String ^ _clrTypeName);public static object Null (string _clrTypeName);static member Null : string -> objPublic Shared Function Null (_clrTypeName As String) As ObjectParameters
- _clrTypeName
- String
The CLR data type to set to nullNothingnullptrunita null reference (Nothing in Visual Basic).
Returns
A CLRObject instance of the specified CLR data type.
Remarks
If you directly set CLR data types to nullNothingnullptrunita null reference (Nothing in Visual Basic) in X++, you only set the kernel reference to nullNothingnullptrunita null reference (Nothing in Visual Basic). This will make it impossible to use the type as a CLR data type. If you assign the CLR data type to CLRInterop:null("yourType"),, the type can be parsed at run time as a parameter of a static method invocation.
The following example sets the CLR string type to nullNothingnullptrunita null reference (Nothing in Visual Basic) and assigns the type value to a CLR object.
static void Job5(Args _args)
{
System.String nullStr;
nullStr = CLRInterop::Null("System.String");
print CLRInterop::isInitialized(nullStr);
print CLRInterop::isNull(nullStr);
}
