例外狀況

範例

以下程式碼範例示範如何使用 GetFileName、 GetExtension和 GetDirectory 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())

備註

若 virtualPath 非根音;即不等於根運算子（波浪號[~]）、不以波浪號（~）開頭，如波浪號與斜線（~/）或波浪與雙反斜線（~//），或不以斜線（/）開頭， ArgumentException 則會拋出例外。

若傳遞到 GetDirectory 方法的虛擬路徑為 "/images/image1.gif"，則回傳的目錄為 "/images"。
