Answer:

IndexOf method is same as String IndexOf method in DotNet.As we know that,IndexOf method is used for searching particular value or text from within string.So it performs same thing with the generic List.It searches List collections and determines the item index of a certain value in the List collection.By using the IndexOf method,we can search for the first position of the value specified in a List collection.
It returns 1 if it finds particular elements in a List otherwise -1 will be returned.

Syntax:-

lst.IndexOf("search any text");
