What do you mean by compare each string to each other? What is it you're trying to achieve?

As F-ES Sitecore said: What do you mean by "compare"?
Check for equality?
Check for some kind of similarity?
??

I would go for two for loops instead of one foreach:

C#

List<String> listA = new List<string> { "ramesh", "rammi", "ramu", "ramarao", "raja", "rajesh" };
 
for (int i = 0; i < listA.Count - 1; i++)
{
   for (int j = i + 1; j < listA.Count; j++)
   {
      // Here you can compare listA[i] and listA[j]
   }
}
