How to get selected text printer Name from selected option drop down on post method?
问题
在页面模型的OnPostPrintAdc方法中，您可以通过Request.Form来获取选择的打印机名称的文本。以下是如何在该方法中获取所选打印机名称的文本：
public void OnPostPrintAdc()
{
string selectedPrinterName = Request.Form["selectprinterid"];
// 现在，selectedPrinterName 包含了所选打印机的名称文本
// 您可以在这里执行您希望的操作
}
这样，您就可以在OnPostPrintAdc方法中获取所选打印机名称的文本。不需要使用数据库来获取它，只需从表单中获取它即可。
