You cannot assign a TextBox object with a String.
You can only get or set its Text property TxtTrvFrm.Text
不能使用字符串分配 TextBox 对象。您只能获取或设置其 Text 属性TxtTrvFrm.Text
From your example
从你的例子
Wrong:
错误的：
TxtTrvFrm.ToString() = cdrDepart.SelectedDate
Correct:
正确的：
TxtTrvFrm.Text = cdrDepart.SelectedDate.ToString();
You could also use ToString or Text to get the current selected value of datePicker.
您还可以使用 ToString 或 Text 来获取 datePicker 的当前选定值。
//Output: 3/28/2013 12:00:00 AM
TxtTrvFrm.Text = this.datePicker1.ToString();
//Output: 3/28/2013
TxtTrvFrm.Text = this.datePicker1.Text;
//Output: 3/28/2013 12:00:00 AM
TxtTrvFrm.Text = this.datePicker1.SelectedDate.ToString();

尝试使用它的 lambda 版本
cdrDepart.SelectedDatesChanged += (a, b) =>
{
TxtTrvFrm.text = cdrDepart.SelectedDate.Value.ToString("yy'.'MM'.'dd");
};

If you are trying to put them in a variable then try it like this:
如果你想把它们放在一个变量中，那么试试这样：
string date = Convert.ToString(Calendar1.SelectedDate);
TBDate.Text = date;
字符串日期 = Convert.ToString(Calendar1.SelectedDate);
TBDate.Text = 日期；
