Initializes a new instance of the RuleExpressionInfo class.

NameDescription
System_CAPS_pubpropertyExpressionType

Gets the type of the expression.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

The ExpressionType property on RuleExpressionInfo provides the return type of the expression. For example, a binary expression, when evaluated, has a return type of Boolean; or, an expression that accesses a property might return an integer type.

The information in the RuleExpressionInfo can be used to validate the use of the expression. For example, a greater-than test cannot be used to compare two expressions if either returns a Boolean.
