嗨，代码错误！！！ [英] hi, error in code!!!!

问题描述

System.IO.DirectoryInfo di = new System.IO.DirectoryInfo("E:\\Testing");
System.IO.FileSystemInfo[] files = di.GetDirectories();
checkedListBox1.Items.AddRange(files);

Options opt = new Options();
XmlDocument document = new XmlDocument();
XmlElement rootElement = document.CreateElement("Items");
foreach (var itemObj in opt.checkedListBox1.CheckedItems)
{
XmlElement newItem = document.CreateElement("Item");
newItem.InnerText =itemObj.ToString();
rootElement.AppendChild(newItem);
}
document.AppendChild(rootElement);
document.Save("test.xml");

代码出错?！ 选项opt = new Options();"

error at code?! " Options opt = new Options();"

Options opt = new Options();

错误！未定义

代码错误:
Error 1 The type or namespace name ''Options'' could not be found (are you missing a using directive or an assembly reference?)

推荐答案

我认为您是从Internet复制代码并尝试对其进行编译.

I think you are copied code from internet and try to compile it.

http://bytes.com/topic/c-sharp/answers/923938-create-xml-file-using-folder-path[^]

able to find same code from that link.

that is not a complete solution, it is small part of a windows form project. you can''t copy past and run it.

There will be compile errors since you don''t have defined Options in your project. It may be a windows form in that given link.
