) As DAQuality
'Usage
 
Dim internalValue As DAQualities

Parameters

internalValue
Enumerated value to be converted.

Return Value

Returns a DAQuality converted from the input argument.

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

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

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.

Requirements
