System.Data Namespace ConstraintCollection Class
Returns the index of the specified Constraint.
Returns the index of the specified Constraint.
Returns the index of the Constraint, specified by name.
The following example uses the IndexOf method to return the index of a Constraint. The index is passed to the Contains method to determine if the collection contains the constraint, before removing it.
NOTE: This example uses one of the overloaded versions of IndexOf. For other examples that may be available, see the individual overload topics.
private void RemoveConstraint ( ConstraintCollection myConstraints,
Constraint myConstraint ) {
try {
if ( myConstraints.Contains ( myConstraint.ConstraintName ) ) {
if ( myConstraints.CanRemove ( myConstraint ) ) {
myConstraints.RemoveAt (
myConstraints.IndexOf ( myConstraint.ConstraintName ) );
}
}
}
catch ( Exception myException ) {
Response.Write ( myException.Message );
}
}
Private Sub RemoveConstraint ( myConstraints As ConstraintCollection, _
myConstraint As Constraint )
Try
If myConstraints.Contains ( myConstraint.ConstraintName ) Then
If myConstraints.CanRemove ( myConstraint ) Then
myConstraints.RemoveAt _
( myConstraints.IndexOf ( myConstraint.ConstraintName ) )
End If
End If
Catch myException As Exception
Response.Write ( myException.Message )
