Constructor
Properties
Columns |
Gets the array of columns that this constraint constrains. |
ConstraintName (inherited from Constraint) |
The name of this constraint within the ConstraintsCollection. An ArgumentException is thrown if setting the name to null or empty string and the column belongs to a collection. A DuplicateNameException is thrown if this column belongs to a collection and it already has a column with the same name (case insensitive). |
DataSet |
Gets the DataSet to which this constraint belongs. |
IsPrimaryKey |
Gets a value indicating whether or not the constraint is on a primary key. |
Table |
Gets the table to which this constraint belongs. |
Methods
Equals |
Compares twhis constraint to a second to determine if both are identical. |
GetHashCode (inherited from Object) |
Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. |
GetType (inherited from Object) |
Gets the Type of the Object. |

Properties
_DataSet (inherited from Constraint) |
Gets the DataSet to which this constraint belongs. |
Methods
CheckStateForProperty (inherited from Constraint) |
[To be supplied.] |
Finalize (inherited from Object) |
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by the Garbage Collector (GC). This method may be ignored by the runtime; therefore, necessary cleanup operations should be done elsewhere. |
MemberwiseClone (inherited from Object) |
Creates a shallow copy of the current Object. |
SetDataSet (inherited from Constraint) |
Sets the constraint's DataSet. |
