DBBool Struct Reference Represents Null, False, and True. More... List of all members. Public Member Functions   DBBool (int value)   Private instance constructor. The value parameter must be –1, 0, or 1. override bool  Equals (object o)   Determines whether two DBBool instances are equal. override int  GetHashCode ()   Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. override string  ToString ()   Returns a string representation of the current Object. Static Public Member Functions static implicit  operator DBBool (bool x)   Implicit conversion from bool to DBBool. Maps true to DBBool.True and false to DBBool.False. static  operator bool (DBBool x)   Explicit conversion from DBBool to bool. static DBBool  operator== (DBBool x, DBBool y)   Equality operator. static DBBool  operator!= (DBBool x, DBBool y)   Inequality operator. static DBBool  operator! (DBBool x)   Logical negation operator. static DBBool  operator & (DBBool x, DBBool y)   Logical AND operator. static DBBool  operator| (DBBool x, DBBool y)   Logical OR operator. static bool  operator true (DBBool x)   Definitely true operator. static bool  operator false (DBBool x)   Definitely false operator. Public Attributes sbyte  value   Private field that stores –1, 0, 1 for False, Null, True. Static Public Attributes static readonly DBBool  Null = new DBBool(0)   A DBBool containing 'Null'. static readonly DBBool  False = new DBBool(-1)   A DBBool containing 'False'. static readonly DBBool  True = new DBBool(1)   A DBBool containing 'True'. Properties bool  IsNull   Properties to examine the value of a DBBool. bool  IsFalse   Properties to examine the value of a DBBool. bool  IsTrue   Properties to examine the value of a DBBool. Detailed Description Represents Null, False, and True. Source: Microsoft c# example Member Function Documentation override bool Equals (  object  o  )    Determines whether two DBBool instances are equal. Parameters: o  The object to check. Returns: True if the two DBBools are equal. override int GetHashCode (   )    Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. Returns: A hash code for the current DBBool. static DBBool operator & (  DBBool  x, DBBool  y )  [static]   Logical AND operator. Parameters: x  a DBBool y  a DBBool Returns: Returns False if either operand is False, otherwise Null if either operand is Null, otherwise True. static operator bool (  DBBool  x  )  [explicit, static]   Explicit conversion from DBBool to bool. Exceptions: InvalidOperationException  The given DBBool is Null Parameters: x  a DBBool Returns: true or false static implicit operator DBBool (  bool  x  )  [static]   Implicit conversion from bool to DBBool. Maps true to DBBool.True and false to DBBool.False. Parameters: x  a DBBool static bool operator false (  DBBool  x  )  [static]   Definitely false operator. Parameters: x  a DBBool Returns: Returns true if the operand is False, false otherwise. static bool operator true (  DBBool  x  )  [static]   Definitely true operator. Parameters: x  a DBBool Returns: Returns true if the operand is True, false otherwise. static DBBool operator! (  DBBool  x  )  [static]   Logical negation operator. Parameters: x  a DBBool Returns: Returns True if the operand is False, Null if the operand is Null, or False if the operand is True. static DBBool operator!= (  DBBool  x, DBBool  y )  [static]   Inequality operator. Parameters: x  a DBBool y  a DBBool Returns: Returns Null if either operand is Null, otherwise returns True or False. static DBBool operator== (  DBBool  x, DBBool  y )  [static]   Equality operator. Parameters: x  a DBBool y  a DBBool Returns: Returns Null if either operand is Null, otherwise returns True or False. static DBBool operator| (  DBBool  x, DBBool  y )  [static]   Logical OR operator. Parameters: x  a DBBool y  a DBBool Returns: Returns True if either operand is True, otherwise Null if either operand is Null, otherwise False. override string ToString (   )    Returns a string representation of the current Object. Exceptions: InvalidOperationException  Object has not been initialized. Returns: A string containing DBBool.False, DBBool.Null, or DBBool.True Member Data Documentation readonly DBBool False = new DBBool(-1) [static]   A DBBool containing 'False'. One of three possible DBBool values. readonly DBBool Null = new DBBool(0) [static]   A DBBool containing 'Null'. One of three possible DBBool values. readonly DBBool True = new DBBool(1) [static]   A DBBool containing 'True'. One of three possible DBBool values. Property Documentation bool IsFalse [get]   Properties to examine the value of a DBBool. Return true if this DBBool has the given value, false otherwise. bool IsNull [get]   Properties to examine the value of a DBBool. Return true if this DBBool has the given value, false otherwise. bool IsTrue [get]   Properties to examine the value of a DBBool. Return true if this DBBool has the given value, false otherwise.
