(code modified from <a href="https://stackoverflow.com/questions/671968/retrieving-property-name-from-lambda-expression">Retrieving Property name from lambda expression</a>)</p> <pre><code>public PropertyInfo GetPropertyInfo<TProperty>( Expression<Func<TProperty>> propertyLambda) { MemberExpression member = propertyLambda.Body as MemberExpression; if (member == null) throw new ArgumentException(string.Format( "Expression '{0}' refers to a method, not a property.", propertyLambda.ToString())); PropertyInfo propInfo = member.Member as PropertyInfo; if (propInfo == null) throw new ArgumentException(string.Format( "Expression '{0}' refers to a field, not a property.", propertyLambda.ToString())); return propInfo; } </code></pre> <p>You don't need to use it as an extension method (though if you want to adapt it you <em>can</em>, but having a source object instance is not necessary except to write the line)</p> <pre><code>public class Test { public string Prop { get; set; } } Test t = new Test(); PropertyInfo propInfo = GetPropertyInfo(() => t.Prop); Console.WriteLine(propInfo.Name + " -> " + propInfo.PropertyType); //Prop -> System.String </code></pre> <p>EDIT: If you want to have some nice syntax and have to avoid having an existing reference to an object of the type, you can do something like:</p> <pre><code>public static class TypedReflection<TSource> { public static PropertyInfo GetPropertyInfo<TProperty>( Expression<Func<TSource, TProperty>> propertyLambda) { MemberExpression member = propertyLambda.Body as MemberExpression; if (member == null) throw new ArgumentException(string.Format( "Expression '{0}' refers to a method, not a property.", propertyLambda.ToString())); PropertyInfo propInfo = member.Member as PropertyInfo; if (propInfo == null) throw new ArgumentException(string.Format( "Expression '{0}' refers to a field, not a property.", propertyLambda.ToString())); return propInfo; } } </code></pre> <p>And call it like:</p> <pre><code>PropertyInfo propInfo = TypedReflection<Test>.GetPropertyInfo(o => o.Prop); </code></pre> <p>At this point, it's pretty easy to add additional typed reflection methods (get methods, fields, etc.)</p> <p>EDIT: It's still sorta two generic types dependent, but it's hidden away through type inference. I prefer the second example; at the very minimum you need to specify the declaring class type (because you want type safety), but you don't need an object instance. It also has the benefit (which I suspect you're after) that if you rename the property, it's propagated to this code obtaining the <code>PropertyInfo</code>.</p>
