I have a label and on this label I have a field that is very large.

I need to break the line, to go to the bottom line when it reaches a certain number of characters.

etqfracpic1.Add("Cas: " + reader[10].ToString()); 
// como estou passando o comando

How can I do this?

I'm sorry to follow the complete code.

List<string> etqfracpic = new List<string>();
    List<string> etqfracpic1 = new List<string>();

    public frmEtqFracPic(string guiapic)
    {
        InitializeComponent();
        txt_guia.Text = guiapic;
    }
    private void etqfrac()
    {
        conex.Open();
        SqlCommand comando;

        StringBuilder Query = new StringBuilder();
        Query.Append("   SELECT                                                                                     ");
        Query.Append("   CAST(0 AS bit) AS SELECIONAR                                                               ");
        Query.Append("   ,SC.C2_NUM                                                                                  ");
        Query.Append("   ,SB.B1_DESC                                                                                ");

The @Rovann Linhalis gave the answer to the question. You can use a method to wrap the string

public static string WrapString(string text, int len)
{
    int x =len;
    while (x < text.Length)
    {
        text = text.Insert(x,"\r\n");
        x += len+2;
    }

    return text;
}
