Get Property Name via Lambda Expression

To use it do something like this.PropertyName(()=>this.Property);

using System;
using System.Linq.Expressions;
using System.Reflection;
private string PropertyName<T>(Expression<Func<T>> property)
{
    var propertyInfo = (property.Body as MemberExpression).Member as PropertyInfo;
    if (propertyInfo == null)
    {
      throw new ArgumentException("The lambda expression 'property' should point to a valid Property");
    }
    var propertyName = propertyInfo.Name;
    return propertyName;
}
