ArgumentException

No property named propertyName is defined in expression.Type or its base types.

The Type property of the resulting MemberExpression is equal to the PropertyType property of the PropertyInfo that represents the property denoted by propertyName.

This method searches expression.Type and its base types for a property that has the name propertyName. Public properties are given preference over non-public properties. If a matching property is found, this method passes expression and the PropertyInfo that represents that property to Property.
