How to remove an item in a list that equals a specific string

I have a list that contains this data: "start it", "start it now", "don't start it".

I need to find and remove items that are equal to "start it". Is there a simple way to do that?

This might do the trick for you

List<string> items = new List<string>() { "start it now", "start it", "don't start it" };
items.RemoveAll(x => x.Equals("start it"));
//or
items.RemoveAll(x => x == "start it");

Both, Contains and Equals are using string comparison. Since your comparison is of type string, Contains will check if the passed parameter is part of the string, whereas Equals compares the complete string for equality.

try this:

 string   mystring = "start it,start it now,don't start it";
 ArrayList strings = new ArrayList(mystring.Split(new char[] { ',' }));

 for (int i = 0; i <strings.Count; i++)
 {
     if (strings[i].ToString()=="start it")
     {
         strings.RemoveAt(i);
     }
 }

and dont forget: using System.Collections;

Try this:

It removes all the string thatis equal to "start it".

list.RemoveAll(x => x.Equals("start it"));

It removes all the string that contains the sentence"start it".

list.RemoveAll(x => x.Contains("start it"));

If you want to delete all items that contain that substring "start it" you have to do

List<string> items = new List<string>() { "start it", "start it now", "don't start it" };
items.RemoveAll(x => x.Contains("start it"));

if you want to remove all items that equal "start it" you have to

items.RemoveAll(x => x == "start it");

Here is what you can do:
