MakeArrayType Method (VarType)



OpcLabs.BaseLib Assembly > OpcLabs.BaseLib.ComInterop Namespace > VarType Class : MakeArrayType Method
Returns a VarType object representing an array of the current type.
Syntax
'Declaration
 
Public Function MakeArrayType() As VarType
'Usage
 
Dim instance As VarType
Dim value As VarType
 
value = instance.MakeArrayType()
public VarType MakeArrayType()
public:
VarType^ MakeArrayType(); 

Return Value

A VarType object representing an array of the current type.

Because there is an implicit conversion from VarType to System.Int32 and VarTypes, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the return value in place of an integer (System.Int32) (representing the numerical value of the COM VARTYPE), or in place a VarTypes enumeration value. When the implicit conversion operators are not supported (such as with Python.NET), you can use the ToInt32 or ToVarTypes static method instead.

This method never returns null (Nothing in Visual Basic).

Exceptions
ExceptionDescription

A method call was invalid for the object's current state.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.
