The value of this property cannot be null (Nothing in Visual Basic).
| Exception | Description |
|---|---|
| System.ArgumentNullException |
A 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. |
Because there are implicit conversions to DAQuality from System.Int32 or DAQualities, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the internal value of the quality), or an element of the DAQualities enumeration in place of DAQuality value when setting this property, and the corresponding quality specification will be constructed automatically. Conversely, 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 DAQuality Constructor(Int32) or DAQuality Constructor(DAQualities) constructor, or the ToInt32 or ToDAQualities static method instead.
