我有一个打开文件对话框，我试图设置默认文件夹。起初，我不得不将其设置为 Environment.GetFolderPath（Environment.SpecialFolder.Personal）+ @\\ new_folder1和运作良好。但是我把它改为 Environment.GetFolderPath（Environment.SpecialFolder.Personal）+ @\\ new_folder2，它仍然弹出的new_folder1。当我调试它，该对话框的 InitialDirectory 是new_folder2。我删除new_folder1，但是对话仍在寻找它时，它启动。现在有没有引用任何地方在我的code到new_folder1。

任何想法可能发生的事？

编辑：这是code，我建立了我最初的打开文件对话框：

 打开文件对话框DLG =新的OpenFileDialog（）;
 dlg.Filter =XML文件（*的.xml）| *的.xml;
 字符串pathDefault = Environment.GetFolderPath（Environment.SpecialFolder.Personal）+ @\\ new_folder2;
 dlg.InitialDirectory = pathDefault;
 

解决方案

您使用的是 @\\ ......。无论是摆脱@或修改 \\ 到 \ 。

或者，尝试：

I have a OpenFileDialog and I am trying to set the default folder. Initially I had it set to Environment.GetFolderPath(Environment.SpecialFolder.Personal) + @"\\new_folder1" and that worked well. However I changed it to Environment.GetFolderPath(Environment.SpecialFolder.Personal) + @"\\new_folder2" and it still pops up in new_folder1. When I debug it, the dialog's InitialDirectory is new_folder2. I deleted new_folder1, but the dialog still looks for it when it starts up. There are now no references anywhere in my code to new_folder1.

Any ideas as to what might be happening?

Edit: Here is the code where I set up my initial OpenFileDialog:

 OpenFileDialog dlg = new OpenFileDialog();
 dlg.Filter = "XML files (*.xml)|*.xml";
 String pathDefault = Environment.GetFolderPath(Environment.SpecialFolder.Personal) + @"\\new_folder2";
 dlg.InitialDirectory = pathDefault;

You're using @"\\....". Either get rid of the @ or change the \\ to \.

Or, try:

Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal),"new_folder2")
