Retrieving Property name from lambda expression

Question

Is there a better way to get the Property name when passed in via a lambda expression? Here is what i currently have.

eg.

GetSortingInfo         


        

Answer 1

This might be optimal

public static string GetPropertyName(Expression> expr)
{
    var memberAccess = expr.Body as MemberExpression;
    var propertyInfo = memberAccess?.Member as PropertyInfo;
    var propertyName = propertyInfo?.Name;

    return propertyName;
}
