WinCE下的C#开发，备忘录

• 类型转换：

字符串转整型：System.Int32.Parse(字符串)字符串转日期：日期字符串.ToString("yyyy-MM-dd hh:mm:ss")

• 下拉框赋值

ArrayList list = new ArrayList();list.Add(new DictionaryEntry(1, "进入"));list.Add(new DictionaryEntry(2, "离开"));   comboBox1.DataSource = list;comboBox1.DisplayMember = "Value";comboBox1.ValueMember = "Key";     

• 获取下拉框的值

string crlb = this.comboBox1.SelectedValue.ToString() +"," + this.comboBox1.Text;

• ListView获取CheckBox为选中状态的Item，以及删除Item

for (int i = 0; i < this.listView2.Items.Count; i++){    if (listView2.Items[i].Checked == true)// 如果为选中状态    {        ckvalue += this.listView2.Items[i].SubItems[3].Text + ",";// 取值        this.listView2.Items.Remove(this.listView2.Items[i]);// 删除选中行    }}

• List转为数组

List<ryBean> rys = new List<ryBean>();ryBean[] rysArr = rys.ToArray();
