Question

No C# eu tenho um TextBox com a propriedade Multiline como true

Neste TextBox eu coloco um texto com 4 linhas e gostaria de remover a 2ª linha.

Estou tentando assim mas não funciona:

        private void button1_Click(object sender, EventArgs e)
        {
            textbox1.Lines[1].Remove(0);
        }

Alguém sabe como fazer isso?

Você pode fazer isso assim:

            String[] linhas = textBox1.Lines;

            System.Collections.ArrayList lista = new System.Collections.ArrayList(linhas);

            lista.RemoveAt(1);

            linhas = (System.String[])lista.ToArray(Type.GetType("System.String"));

            textBox1.Lines = linhas;

Certo? ;)
