"I tried writing more than one code but it didn't work for me"
And you think maybe we can guess what you did and provide a solution to code that we cannot see?

Please think before you post a question:
What actual code are you using - we need to see it, we have no way of guessing.
What happened when you compiled it - did you get any error messages - we need to see them.
What happened when you ran it - give full details, do not say "it didn't work".

Add your button.
Add a Click handler to your button.
Then in the click handler, read the text from the TextBox.
Then all you have to do is an SQL INSERT to add it to your DB.

Exactly how you INSERT will depend on what DB system you are using, but this will save a string and a DateTime value to SQL Server:

C#

using (SqlConnection con = new SqlConnection(strConnect))
    {
    con.Open();
    using (SqlCommand cmd = new SqlCommand("INSERT INTO myTable (myColumn1Name, myColumn2Name) VALUES (@STR, @DT)", con))
        {
        cmd.Parameters.AddWithValue("@STR", strReadFromTextBox);
        cmd.Parameters.AddWithValue("@DT", DateTime.Now);
        cmd.ExecuteNonQuery();
        }
    }
