    <p>If it helps, our code base uses the following:</p> <pre><code>public class TypeHelper { private static PropertyInfo GetPropertyInternal(LambdaExpression p) { MemberExpression memberExpression; if (p.Body is UnaryExpression) { UnaryExpression ue = (UnaryExpression)p.Body; memberExpression = (MemberExpression)ue.Operand; } else { memberExpression = (MemberExpression)p.Body; } return (PropertyInfo)(memberExpression).Member; } public static string GetPropertyName&lt;TObject&gt;(Expression&lt;Func&lt;TObject, object&gt;&gt; p) { return GetPropertyNameInternal(p); } public static string GetPropertyName&lt;TObject, T&gt;(Expression&lt;Func&lt;TObject, T&gt;&gt; p) { return GetPropertyNameInternal(p); } public static string GetPropertyName&lt;T&gt;(Expression&lt;Func&lt;T&gt;&gt; p) { return GetPropertyNameInternal(p); } public static string GetPropertyName(Expression p) { return GetPropertyNameInternal((LambdaExpression) p); } private static string GetPropertyNameInternal(LambdaExpression p) { return GetPropertyInternal(p).Name; } public static PropertyInfo GetProperty&lt;TObject&gt;(Expression&lt;Func&lt;TObject, object&gt;&gt; p) { return GetPropertyInternal(p); } public static PropertyInfo GetProperty&lt;TObject, T&gt;(Expression&lt;Func&lt;TObject, T&gt;&gt; p) { return GetPropertyInternal(p); } public static PropertyInfo GetProperty&lt;T&gt;(Expression&lt;Func&lt;T&gt;&gt; p) { return GetPropertyInternal(p); } } </code></pre> <p>That gives you the ability to do:</p> <pre><code>var propertyName = TypeHelper.GetPropertyName&lt;Customer&gt;(c =&gt; c.Id); </code></pre> <p>Or</p> <pre><code>var propertyName = TypeHelper.GetPropertyName(() =&gt; this.Id); // If inside Customer class </code></pre>
