好，winforms或webforms，您所需要做的就是在dropdownlist selectionchange事件中编写代码.在这种情况下(当您在下拉列表中选择其他值时会出现此情况)，找到所选值并使用它来获取适当的正文，并将其分配给文本框.
试试吧！
Well, winforms or webforms, all you need is to write the code in the dropdownlist selectionchange event. In the event (which would be raised when you select a different value in your dropdowlist), find the selected value and use it to to get the appropriate body text and assign it to the textbox.
Try!
