ToInt64 Method (DAAccessRight)



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.DataAccess Namespace > DAAccessRight Class : ToInt64 Method
The value to be converted.

Because the DAAccessRight has an implicit conversion from System.Int64 and DAAccessRights, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the numerical value of the access rights), or an element of the DAAccessRights enumeration (or a combination of DAAccessRights flags) in place of this parameter, and the corresponding access rights specification will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the DAAccessRight Constructor(Int64) or DAAccessRight Constructor(DAAccessRights) constructor instead.

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

Converts the access rights object to a long integer value of access rights bits.
Syntax

'Usage
 
Dim accessRights As DAAccessRight

Parameters

accessRights
The value to be converted.

Because the DAAccessRight has an implicit conversion from System.Int64 and DAAccessRights, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the numerical value of the access rights), or an element of the DAAccessRights enumeration (or a combination of DAAccessRights flags) in place of this parameter, and the corresponding access rights specification will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the DAAccessRight Constructor(Int64) or DAAccessRight Constructor(DAAccessRights) constructor instead.

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

Return Value

Returns the value of access rights bits.
Remarks

In languages that support implicit conversions (such as C# or VB.NET), in many cases you do not have call this method explicitly. When indicated, a call to an available equivalent implicit conversion operator will be created by the compiler automatically.
