How do I use the delete statement in a basic CRUD application in C#?

So I'm writing a basic CRUD application for practice as I haven't done it in a while. I came across the delete part of the CRUD application and I came across a problem. I have denoted the error line by the text "error here". Here is my code

string query = "DELETE FROM Books WHERE Title=@" + deletetitletxtbox.Text;

    using (SqlConnection conn = new SqlConnection(connString))
    using (SqlCommand command = new SqlCommand(query, conn))
        {
            conn.Open();

            command.Parameters.AddWithValue("@title", deletetitletxtbox.Text);

            command.ExecuteScalar();//error here

            conn.Close();
        }
clear();

The error I am getting is "System.Data.SqlClient.SqlException: 'Must declare the scalar variable "@The".'" So say I want to delete an column with the title of "The Main Book". That error shows up. I have been going at it for a while and have been quite annoyed at it. I apologise in advance if this is a stupid question.

What I have tried:

I have tried looking on other websites to no luck. All of the examples to me seem like they don't fit the issue that I am having. Or maybe I am looking at it wrong. At this stage it is hard to figure it out as my judgement is clouded.
