'/'应用程序中的服务器错误。找不到路径的一部分 [英] Server error in '/' application. Could not find a part of the path

问题描述

我试图在按钮点击时删除xml文件，这些文件位于我网站上的xml文件夹中（在smarterasp.net托管中），使用以下代码：

I'm trying to delete xml files on button click , the files are in the xml folder on my site (in smarterasp.net hosting) using this code :

Protected Sub Button4_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button4.Click
    Dim directoryName As String = MapPath("~/xml/")
    For Each deleteFile In Directory.GetFiles(directoryName, "*.xml", SearchOption.TopDirectoryOnly)
        File.Delete(deleteFile)
    Next
    Label1.Text = "done"
End Sub

但是我收到了这个错误：

but I got this error :

推荐答案

在ASP.NET中获取文件夹的正确方法应用程序是使用MapPath



您可能需要稍微调整一下，因为这是来自控制台应用程序，只是重新声明了FolderPath。

The right way to get the folder within an ASP.NET application is to use MapPath

You may need to adjust this a bit as this was from a console app, and just had the FolderPath redeclared.

string FolderPath = Server.MapPath("\XML");
DirectoryInfo dir = new DirectoryInfo(FolderPath);

try {
	foreach (FileInfo fi in dir.GetFiles()) {
		fi.Delete();
	}
}
catch (Exception ex) {
	MessageBox.Show(ex.Message);
}
