Take a look at this method taken from:

https://github.com/okhosting/OKHOSTING.Data/blob/master/src/PCL/OKHOSTING.Data/Validation/MemberExpression.cs

public static string GetMemberString(System.Linq.Expressions.Expression> member)
    {
        if (member == null)
        {
            throw new ArgumentNullException("member");
        }

        var propertyRefExpr = member.Body;
        var memberExpr = propertyRefExpr as System.Linq.Expressions.MemberExpression;

        if (memberExpr == null)
        {
            var unaryExpr = propertyRefExpr as System.Linq.Expressions.UnaryExpression;

            if (unaryExpr != null && unaryExpr.NodeType == System.Linq.Expressions.ExpressionType.Convert)
            {
                memberExpr = unaryExpr.Operand as System.Linq.Expressions.MemberExpression;

                if(memberExpr != null)
                {
                    return memberExpr.Member.Name;
                }
            }
        }
        else
        {
            //gets something line "m.Field1.Field2.Field3", from here we just remove the prefix "m."
            string body = member.Body.ToString();
            return body.Substring(body.IndexOf('.') + 1);
        }

        throw new ArgumentException("No property reference expression was found.", "member");
    }
