Counting substring occurrences in string[]

Question

Given a String array such as this:

string[]={"bmw"," ","1bmw"," "};

I need to count how often the substring bmw occurs in that array. In this example it occurs 2 times.

How do I write that in C#?

also i want to ignore the capital character,

sting[]={"bmw", "", "BMw","1bmw"}

then the count result is 3.

what should i do?

Thanks for everyone's answer.

Try:

var str = new string[] { "bmw", " ", "1bmw", " " };
var count = str.Count(s => s.Contains("bmw"));

the next code will return the count of case insensitive occurrences (as author mentioned in comments):

var count = str.Count(s =>
    s.IndexOf("bmw", StringComparison.OrdinalIgnoreCase) > -1
);
