Syntax
'Declaration
 
Public Property DataType As SparkplugDataType
'Usage
 
Dim instance As SparkplugMetadata
Dim value As SparkplugDataType
 
instance.DataType = value
 
value = instance.DataType
public SparkplugDataType DataType {get; set;}
public:
property SparkplugDataType DataType {
   SparkplugDataType get();
   void set (    SparkplugDataType value);
}

Property Value

The default value of this property is Unknown (SparkplugDataType.Unknown).

Exceptions
ExceptionDescription

An invalid enumeration value was used.

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.

Remarks

The data type is not part of Sparkplug metadata in the protocol; it is part of the Sparkplug metric itself, and can be found in the DataType property. However, it logically belongs to the metadata too, and that's why it is included in SparkplugMetadata object.
