Get the array element in between a string in c#

Question

I have the String Array.The array contains following.

String [] Array= {"Age18" ,"Ram","Raj" ,"Sonu","Mano","Age20","Ana","Einstein","Somu"};

Now here I want to separate the String between Age 18 and Age 20.

foreach (string line in Array)
{
if (line.Contains("Age18"))
{
//Want to print the Elements of an array before Age20.
//result [] array={"Age18" ,"Ram","Raj" ,"Sonu","Mano"};
}

Help me to solve this.
