 ## Remarks 
  The <xref:System.Linq.Expressions.Expression.Type%2A> property of the resulting <xref:System.Linq.Expressions.MemberExpression> is equal to the <xref:System.Reflection.PropertyInfo.PropertyType%2A> or <xref:System.Reflection.FieldInfo.FieldType%2A> properties of the <xref:System.Reflection.PropertyInfo> or <xref:System.Reflection.FieldInfo>, respectively, that represents the property or field denoted by `propertyOrFieldName`. 
 
- This method searches `expression`.Type and its base types for a property or field that has the name `propertyOrFieldName`. Public properties and fields are given preference over non-public properties and fields. Also, properties are given preference over fields. If a matching property or field is found, this method passes `expression` and the <xref:System.Reflection.PropertyInfo> or <xref:System.Reflection.FieldInfo> that represents that property or field to <xref:System.Linq.Expressions.Expression.Property%2A> or <xref:System.Linq.Expressions.Expression.Field%2A>, respectively.
