Reflection: Get MethodInfo for string.StartsWith [duplicate]

This question already has an answer here:

• Problem with LINQ to Entities and String.StartsWith 1 answer

I need to build Expression Tree for query:

con.Flats.Where(q => q.Street.Title.StartsWith(val, true, new CultureInfo("ru-RU")));

I try getting to StartsWith method using this:

MethodInfo startsMethod = typeof(string).GetMethod("StartsWith", new Type[] { typeof(string), typeof(bool), typeof(CultureInfo) });

I get error:

LINQ to Entities does not recognize the method 'Boolean StartsWith(System.String, Boolean, System.Globalization.CultureInfo)' method, and this method cannot be translated into a store expression.

How do I do it properly?
