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

Indicates whether the current Value is False.

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.

Methods

And(SqlBoolean, SqlBoolean)

Computes the bitwise AND operation of two specified SqlBoolean structures.

CompareTo(Object)

Compares this SqlBoolean structure to a specified object and returns an indication of their relative values.

CompareTo(SqlBoolean)

Compares this SqlBoolean object to the supplied SqlBoolean object and returns an indication of their relative values.

Equals(Object)

Compares the supplied object parameter to the SqlBoolean.

Equals(SqlBoolean, SqlBoolean)

Compares two SqlBoolean structures to determine whether they are equal.

Equals(SqlBoolean)

Indicates whether the current instance is equal to another instance of the same type.

GetHashCode()

Returns the hash code for this instance.

GetXsdType(XmlSchemaSet)

Returns the XML Schema definition language (XSD) of the specified XmlSchemaSet.

GreaterThan(SqlBoolean, SqlBoolean)

Compares two instances of SqlBoolean to determine whether the first is greater than the second.

GreaterThanOrEquals(SqlBoolean, SqlBoolean)

LessThan(SqlBoolean, SqlBoolean)

Compares two instances of SqlBoolean to determine whether the first is less than the second.

LessThanOrEquals(SqlBoolean, SqlBoolean)

Compares two instances of SqlBoolean to determine whether the first is less than or equal to the second.

NotEquals(SqlBoolean, SqlBoolean)

Compares two instances of SqlBoolean for equality.

OnesComplement(SqlBoolean)

Performs a one's complement operation on the supplied SqlBoolean structures.

Or(SqlBoolean, SqlBoolean)

Performs a bitwise OR operation on the two specified SqlBoolean structures.

Parse(String)

Converts the specified String representation of a logical value to its SqlBoolean equivalent.
