Remarks
Any non-zero value is interpreted as 1.
The key difference between a SqlBoolean structure and a standard Boolean value is that, where a standard Boolean has two possible values, true and false, a SqlBoolean structure has three possible values, True, False, or Null.
Constructors
| SqlBoolean(Boolean) |
Initializes a new instance of the SqlBoolean structure using the supplied Boolean value. |
| SqlBoolean(Int32) |
Initializes a new instance of the SqlBoolean structure using the specified integer value. |
Fields
| False |
Represents a false value that can be assigned to the Value property of an instance of the SqlBoolean structure. |
| Null |
Represents DBNull that can be assigned to this instance of the SqlBoolean structure. |
| One |
Represents a one value that can be assigned to the ByteValue property of an instance of the SqlBoolean structure. |
| True |
Represents a true value that can be assigned to the Value property of an instance of the SqlBoolean structure. |
| Zero |
Represents a zero value that can be assigned to the ByteValue property of an instance of the SqlBoolean structure. |
Properties
| ByteValue |
Gets the value of the SqlBoolean structure as a byte. |
| IsFalse | |
| IsNull |
Indicates whether this SqlBoolean structure is null. |
| IsTrue |
Gets a value that indicates whether the current Value is True. |
| Value |
Gets the SqlBoolean structure's value. This property is read-only. |
