SequenceEqual in C# List

Hi,

I have 2 List<string>: list_A and list_B.
it has 3 items inside each.

I got the values from api call and they are:
Iist_A[0] : "Hello"
list_A[1]: "I am <br><br> Isabell"
list_A[2]: "Sincerely, <br><br>Isabell"

I retrieved the values from DB and stored those to list_B.
I added and deleted items on list_B since I had to manipulate the data and string.
So when I finally added items, the previously stored items were overwritten by the new ones.
However, at the end, this is what I got for list_B.
Iist_B[0] : "Hello"
list_B[1]: "I am <br><br> Isabell"
list_B[2]: "Sincerely, <br><br>Isabell"

When I checked the values using Locals window in Visual Studio, I verified that all the values were matched. I even used 'Text Visualizer', but the results were exactly matched.
However I am getting "false" on the following statement.

list_A.SequenceEqual(list_B);

How could this happen and how to fix this issue?

it should be equals and returned true if you compare to 2 same Lists

try check the 1st and 2nd results below
List<string> list_A = new List<string> { "Hello", "I am <br><br> Isabell", "Sincerely, <br><br>Isabell" };
            List<string> list_B = new List<string> { "Hello", "I am <br><br> Isabell", "Sincerely, <br><br>Isabell" };

            Boolean b = list_A.SequenceEqual(list_B);
            Response.Write("B = " + b.ToString() + "<br>");

            list_B.Add("test");
            b = list_A.SequenceEqual(list_B);
            Response.Write("B = " + b.ToString() + "<br>");

I have copied your values to my code (below) - and it shows that lists are identical...:

            List<string> list_A = new List<string>();
            list_A.Add("Hello");
            list_A.Add("I am <br><br> Isabell");
            list_A.Add("Sincerely, <br><br>Isabell");
            List<string> list_B = new List<string>();
            list_B.Add("Hello");
            list_B.Add("I am <br><br> Isabell");
            list_B.Add("Sincerely, <br><br>Isabell");

            MessageBox.Show((list_A.SequenceEqual(list_B)).ToString());
