初始化字符串的格式不符合从索引73开始的规范

我使用sql db在c#中创建应用程序,当我在应用程序中保存数据时,在“system.argumentException”中显示错误“初始化字符串的格式不符合从索引73开始的规范”

我使用windows autentication和此代码进行连接:

   public static SqlConnection ObtenerConexion() 
   {
       SqlConnection Conn = new SqlConnection("Data source=VICTOR-PC; Initial Catalog=KAZIIM;  Integrated Security=True;");
       Conn.Open();


       return Conn;

   }
}

和保存数据的代码是:

 private void btnGuardar_Click(object sender, EventArgs e)
    {
        Cliente Cliente = new Cliente();
        Cliente.ID_C = int.Parse(txtID.Text);
        Cliente.NOMBRES = txtNombres.Text;
        Cliente.CONTACTO = txtCorreo.Text;
        Cliente.CALLE = txtCalle.Text;
        Cliente.NUMERO = int.Parse(txtNumero.Text);
        Cliente.COLONIA = txtColonia.Text;
        Cliente.FECHA_ALTA = txtFecha.Text;

        int resultado = ClienteDAL.Agregar(Cliente);

        if (resultado > 0)
        {
            MessageBox.Show("Datos guardados con exito", "Datos Guardado", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }
        else
        {
            MessageBox.Show("No se grabaron los datos", "Error al guardar", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
        }

,例外细节是:

在连接字符串的最末端,;"字符之间似乎有一个UTF-8字节顺序标记,正好在错误所在的字符位置。它是不可见的,但如果您将其复制到新的文本文件并使用UTF-8编码保存并在十六进制编辑器中检查该文件,则可以看到它。只需删除最后几个字符并再次输入即可。

"Data source=VICTOR-PC; Initial Catalog=KAZIIM; Integrated Security=True;<some invisible stuff is here>"
