示例

下面的代码示例演示如何使用GetFileName和GetExtensionGetDirectory方法。

StringBuilder sb = new StringBuilder();
String pathstring = Context.Request.FilePath.ToString();
sb.Append("Current file path = " + pathstring + "<br />");
sb.Append("File name = " + VirtualPathUtility.GetFileName(pathstring).ToString() + "<br />");
sb.Append("File extension = " + VirtualPathUtility.GetExtension(pathstring).ToString() + "<br />");
sb.Append("Directory = " + VirtualPathUtility.GetDirectory(pathstring).ToString() + "<br />");
Response.Write(sb.ToString());

Dim sb As New StringBuilder()
Dim pathstring As String = Context.Request.FilePath.ToString()
sb.Append("Current file path = " & pathstring & "<br />")
sb.Append("File name = " & VirtualPathUtility.GetFileName(pathstring).ToString() & "<br />")
sb.Append("File extension = " & VirtualPathUtility.GetExtension(pathstring).ToString() & "<br />")
sb.Append("Directory = " & VirtualPathUtility.GetDirectory(pathstring).ToString() & "<br />")
Response.Write(sb.ToString())

注解

如果未 virtualPath 建立 root;也就是说，它不等于根运算符（波形符 [~]），不以波形符（~）开头，如波形符和斜杠（~/）或平铺和双反斜杠（~/），或者不以斜杠标记（/）开头， ArgumentException 将引发异常。

如果传入方法的 GetDirectory 虚拟路径为 "/images/image1.gif"，则返回的目录为 "/images"。
