GetDataCommand Constructor

GetDataCommand()

Initializes a new instance of the GetDataCommand class.

C#

public GetDataCommand()

Remarks

This constructor is provided for those developers who want to use the object initializer pattern. For example:

var getDataCommand = new GetDataCommand()
{
    DataTag = (int)PivDataTag.Authentication,
};

There is no default data tag, hence, for this command to be valid, the tag must be specified. So if you create an object using this constructor, you must set the DataTag property at some time before using it. Otherwise you will get an exception when you do use it.

The valid data tags are numbers from 0x005F0000 to 0x005FFFFF inclusive, along with 0x0000007E and 0x00007F61.
