Inequality Operator (VarType)



OpcLabs.BaseLib Assembly > OpcLabs.BaseLib.ComInterop Namespace > VarType Class : Inequality Operator
First object to be compared.

Because the VarType has an implicit conversion from System.Int32 and VarTypes, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the numerical value of the COM VARTYPE), or an element of the VarTypes enumeration (or an allowed combination of VarTypes flags) in place of this parameter, and the corresponding data type specification will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the VarType Constructor(Int32) or VarType Constructor(VarTypes) constructor instead.

The value of this parameter can be null (Nothing in Visual Basic).
