Delete items in a list based on its value in ASP.NET

I have a list of string:

List<string> productsAll = new List<string>();
productsAll.Add("CMT_40");
productsAll.Add("CMT_50");
productsAll.Add("Mortar");

How do I remove the items at productsAll without using productsAll.RemoveAt?

I can't delete the value based on index, as productsAll will be heavily modified with each interactions in the page.

Remove is a nice option to remove a specific item from the list, if you want to remove more than one elements means you can try RemoveAll as well. you can try the following code:

List<string> productsAll = new List<string>();
productsAll.Add("CMT_40");
productsAll.Add("CMT_50");
productsAll.Add("Mortar");
productsAll.Add("Mortar");
productsAll.Add("Mortar");
string itemToRemove = "Mortar";

productsAll.RemoveAll(x=>x==itemToRemove);

Check this Example for working demo. You can also try removing items that contains specific text by using .Contains() by using the following code:

 productsAll.RemoveAll(x=>x.Contains(itemToRemove));

You can just remove item from the list if you know the item you would like to delete

Use 

productsAll.Remove("item123");
